In particular, the invention relates to such a device making it possible to reproduce certain beneficial effects of the presence of a reference person, such as a parent, in the immediate vicinity of a child, particularly of a newborn child, and more particularly of a premature newborn.
[003] L'invention concerne également un procédé pouvant être mis en oeuvre par un tel dispositif, pour procurer à un enfant, particulièrement à un enfant nouveau-né, certains des effets bénéfiques liés à la proximité d'une personne. The invention also relates to a method that can be implemented by such a device, to provide a child, particularly a newborn child, some of the beneficial effects associated with the proximity of a person.
Art antérieur Prior art
[004] Selon la présente invention, on désigne par enfant nouveau-né ou « nouveau- né » un enfant qui a moins de 28 jours. Un nouveau-né prématuré, ou prématuré est un enfant qui naît avant 8 mois et demi de grossesse (37 semaines d'aménorrhée). La présente invention s'applique en particulier à de tels enfants nouveau-nés, et plus particulièrement à des nouveau-nés prématurés. Elle peut cependant s'appliquer plus généralement à de jeunes enfants, et en particulier à de jeunes enfants malades ou souffrant de handicap, devant séjourner dans un milieu hospitalier ou dans des structures d'accueil médicalisé ou encore à des plus âgés présentant des troubles cognitifs. [004] According to the present invention, the term “newborn child” or “newborn” denotes a child who is less than 28 days old. A premature or premature newborn is a child born before 8 and a half months of pregnancy (37 weeks of amenorrhea). The present invention applies in particular to such newborn children, and more particularly to premature newborns. However, it can be applied more generally to young children, and in particular to young children who are sick or suffering from a disability, having to stay in a hospital environment or in nursing homes or even older children with cognitive disorders. .
[005] Les nouveau-nés naissants prématurément, ou souffrant de pathologies néonatales, sont généralement hospitalisés pendant une période pouvant durer plusieurs mois. En fonction de leur degré de prématurité, et des éventuelles pathologies dont ils peuvent être atteints, ils sont souvent placés dans des berceaux appelés couveuses ou incubateurs, dans lesquels la température varie pour maintenir la température du corps humain, l'hygrométrie est ajustée en fonction du besoin et l'environnement est protégée des contaminations. Dans d'autres cas, ils peuvent être placés, en milieu hospitalier, dans des lits ouverts chauffants, ou tables radiantes. Ces nouveau-nés peuvent parfois être éclairés par des lampes à ultraviolets. [005] Newborns born prematurely, or suffering from neonatal pathologies, are generally hospitalized for a period which may last several months. Depending on their degree of prematurity, and any pathologies which they can be reached, they are often placed in cradles called incubators or incubators, in which the temperature varies to maintain the temperature of the human body, the hygrometry is adjusted according to the need and the environment is protected from contamination. In other cases, they can be placed, in a hospital environment, in heated open beds, or radiant tables. These newborns can sometimes be illuminated by ultraviolet lamps.
[006] Dans un environnement médicalisé, les contacts directs du nouveau-né avec les adultes qui l'entourent, et notamment avec sa mère, sont nécessairement limités dans le temps. [006] In a medical environment, the direct contacts of the newborn with the adults around him, and in particular with his mother, are necessarily limited in time.
[007] Pourtant, les soins dits « de développement » incitent et encouragent la présence de personnes de référence, et en particulier de la mère, à proximité du nouveau-né. Selon la présente invention, « une personne de référence » est une personne présentant un lien affectif particulier avec le nouveau-né, en particulier un parent du nouveau-né, un membre de sa famille, ou une personne s'occupant particulièrement du nouveau-né. [007] However, so-called “development” care encourages and encourages the presence of reference persons, and in particular of the mother, near the newborn. According to the present invention, "a reference person" is a person having a particular emotional bond with the newborn, in particular a parent of the newborn, a member of his family, or a person particularly caring for the newborn. not.
[008] Il est en effet reconnu que la présence d'une personne de référence, et principalement de sa mère, à proximité immédiate du nouveau-né, lui procure des effets utiles à son développement psychique, voire physique. Une telle présence revêt une importance particulière dans le cas des nouveau-nés prématurés. [008] It is in fact recognized that the presence of a reference person, and mainly of his mother, in the immediate vicinity of the newborn, provides him with useful effects for his psychic or even physical development. Such a presence is of particular importance in the case of premature infants.
[009] Cependant, les conditions d'hospitalisation, l'état de santé des nouveau-nés, et la durée de ces hospitalisations, ne permettent pas aux personnes de référence d'assurer une présence à proximité immédiate du nouveau-né aussi régulière qu'ils le souhaiteraient. En particulier, les sorties de la couveuse ou du lit chauffant pour des contacts peau à peau sont limitées. Le brevet CN1107475 décrit une méthode capable de favoriser le développement du cortex cérébral du langage auditif d'un enfant prématuré. [009] However, the conditions of hospitalization, the state of health of the newborns, and the duration of these hospitalizations, do not allow the reference persons to ensure a presence in the immediate vicinity of the newborn as regular as 'they would like. In particular, the outputs of the incubator or the heating bed for skin-to-skin contact are limited. Patent CN1107475 describes a method capable of promoting the development of the cerebral cortex of the auditory language of a premature child.
[010] Il a par ailleurs été observé que les enfants nés prématurément souffraient, plus souvent que la moyenne, de troubles de l'audition ou de troubles du comportement. Selon certaines hypothèses, certains de ces troubles pourraient être causés par l'exposition des nouveau-nés prématurés à des bruits inappropriés en volume, fréquence et répétabilité avant que son oreille ne soit parfaitement formée. Pour éviter de tels troubles, des recommandations d'ambiance sonore ont été émises pour les conditions de soins hospitaliers. Il est ainsi recommandé de parler doucement à proximité immédiate d'un nouveau-né prématuré. Objectifs de l'invention [010] It has also been observed that children born prematurely suffered, more often than average, from hearing disorders or behavioral disorders. According to some hypotheses, some of these disorders could be caused by the exposure of premature newborns to inappropriate noises in volume, frequency and repeatability before his ear is perfectly formed. To avoid such disturbances, sound environment recommendations have been issued for hospital care conditions. It is therefore recommended to speak softly in the immediate vicinity of a premature newborn baby. Objectives of the invention

[016] Encore un autre objectif de l'invention est de fournir un tel dispositif qui soit facile à paramétrer et à utiliser. [015] A particular objective of the invention is to provide such a device which avoids any disturbance in the state of health of the child, even in the event of an error in the use of the device. [016] Yet another objective of the invention is to provide such a device which is easy to configure and to use.

[039] According to an advantageous characteristic, the sound processing and diffusion device comprises a cover 2 made of textile material, surrounding the housing 1. This cover 2 is advantageously removable, and can be removed from the sound processing and distribution device. and be worn by the reference person whose presence we want to simulate with a child, in order to soak up his scent. Thus, when the cover 2 is replaced on the housing 1, it diffuses the smell of the reference person. It is also possible that the sound processing and distribution device is supplied with several covers, so that the reference person can wear one to impregnate him with his scent, while the other is placed on the housing. 1. In Figure 1, only the outlines of the cover 2 are shown in dotted lines, so that the housing 1 and the contents thereof remain visible in the figure.
[040] Ce boîtier 1 renferme notamment au moins une batterie 3, un haut-parleur 4 et une carte électronique 5, connectés entre eux. La carte électronique 5 porte notamment un microcontrôleur 51, un composant de traitement du son 52, un microphone 53, une diode électroluminescente 54, une prise d'alimentation 55 et un bouton de commande 56. [040] This housing 1 notably contains at least one battery 3, a loudspeaker 4 and an electronic card 5, connected together. The electronic card 5 notably carries a microcontroller 51, a sound processing component 52, a microphone 53, a light-emitting diode 54, a power socket 55 and a control button 56.
[041] Le microcontrôleur 51 assure notamment le contrôle de tous les autres composants, de façon à ce que le dispositif de traitement et de diffusion de sons puisse mettre en oeuvre plusieurs fonctionnalités, parmi lesquelles les fonctionnalités suivantes : [041] The microcontroller 51 notably ensures the control of all the other components, so that the sound processing and diffusion device can implement several functionalities, among which the following functionalities:
- une fonctionnalité d'enregistrement, mise en oeuvre notamment par le microcontrôleur 51, le composant de traitement du son 52 et le microphone 53 ; a recording functionality, implemented in particular by the microcontroller 51, the sound processing component 52 and the microphone 53;
- une fonctionnalité de diffusion sonore, mise en oeuvre notamment par le microcontrôleur 51, le composant de traitement du son 52 et le haut-parleur 4 ; a sound diffusion functionality, implemented in particular by the microcontroller 51, the sound processing component 52 and the loudspeaker 4;
- une fonctionnalité de chargement des batteries, mise en oeuvre notamment par le microcontrôleur 51, la prise d'alimentation 55 et les batteries 3. a battery charging functionality, implemented in particular by the microcontroller 51, the power socket 55 and the batteries 3.
[042] Le microcontrôleur 51 permet avantageusement d'affecter le dispositif de traitement et de diffusion de sons à l'une ou l'autre des fonctionnalités indiquées ci- dessus. De préférence, ces fonctionnalités ne sont pas mises en oeuvre simultanément. [043] Le microcontrôleur 51 permet de placer le dispositif de traitement et de diffusion de sons dans différents états distincts. Parmi ces états : [042] The microcontroller 51 advantageously makes it possible to assign the device for processing and broadcasting sounds to one or other of the functions indicated above. Preferably, these functionalities are not implemented simultaneously. [043] The microcontroller 51 makes it possible to place the device for processing and broadcasting sounds in different distinct states. Among these states:
- un état d'enregistrement, dans lequel la fonctionnalité d'enregistrement permet l'enregistrement et le traitement de sons, - a recording state, in which the recording functionality allows the recording and processing of sounds,
- un état de diffusion sonore, au cours duquel la fonctionnalité de diffusion sonore permet la diffusion de sons, pouvant comprendre une ou plusieurs pistes sonores enregistrées précédemment, - a sound broadcast state, during which the sound broadcast functionality allows sound to be broadcast, which may include one or more previously recorded sound tracks,
- un état de chargement des batteries, au cours duquel le dispositif de traitement et de diffusion de sons est connecté à une source d'alimentation électrique, et la fonctionnalité de chargement des batteries est active - a battery charging state, during which the sound processing and distribution device is connected to a power source, and the battery charging functionality is active
[044] Quand la prise d'alimentation 55 n'est pas branchée à une alimentation électrique, les appuis d'un utilisateur sur le bouton de commande 56 permettent de transmettre au microcontrôleur 51 les instructions de mettre le dispositif dans l'un des états d'enregistrement ou de diffusion sonore. De façon avantageuse, le microcontrôleur 51 est capable de détecter le branchement d'une alimentation électrique sur la prise d’alimentation 55. Dans ce cas, il met le dispositif de traitement et de diffusion de sons dans l'état de chargement des batteries 3, en interrompant, le cas échéant, l'état d'enregistrement ou l'état de diffusion sonore. Une telle interruption des fonctionnalités de diffusion sonore et d'enregistrement, quand le dispositif de traitement et de diffusion de sons est branché à une alimentation électrique, permet avantageusement d'éviter tout risque d'accident d'origine électrique. [044] When the power socket 55 is not connected to a power supply, the presses of a user on the control button 56 make it possible to transmit to the microcontroller 51 the instructions to put the device in one of the states. sound recording or broadcasting. Advantageously, the microcontroller 51 is capable of detecting the connection of an electrical power supply to the power supply socket 55. In this case, it places the sound processing and distribution device in the state of charging the batteries 3. , by interrupting, if necessary, the recording state or the sound broadcasting state. Such an interruption of the sound broadcasting and recording functionalities, when the sound processing and broadcasting device is connected to an electrical supply, advantageously makes it possible to avoid any risk of accident of electrical origin.
[045] Dans l'état d'enregistrement, la fonctionnalité d'enregistrement du dispositif de traitement et de diffusion de sons est activée. Cette fonctionnalité d'enregistrement est mise en œuvre par les composants électroniques qui ont pour fonctionnalité d'enregistrer les sons environnants et de traiter les sons en vue de leur diffusion, et notamment le microphone 53 et le composant de traitement de son 52. [045] In the recording state, the recording functionality of the sound processing and broadcasting device is enabled. This recording functionality is implemented by the electronic components which have the functionality of recording the surrounding sounds and of processing the sounds with a view to their diffusion, and in particular the microphone 53 and the sound processing component 52.
[046] Ce composant de traitement de son 52 peut être un composant électronique dédié au traitement de son. Il peut également être, dans d'autres modes de réalisation, un pilote audio logiciel, fonctionnant par exemple sur le microcontrôleur 51. [047] Selon un mode de réalisation préférentiel, quand le microcontrôleur 51 active la fonctionnalité d'enregistrement, le microphone 53 enregistre un son, de préférence un son dans lequel la voix de la personne de référence apparaît de manière privilégiée. La fonctionnalité d'enregistrement permet ainsi des enregistrements de quelques secondes à quelques minutes. [046] This sound processing component 52 can be an electronic component dedicated to sound processing. It can also be, in other embodiments, a software audio driver, functioning for example on the microcontroller 51. [047] According to a preferred embodiment, when the microcontroller 51 activates the recording functionality, the microphone 53 records a sound, preferably a sound in which the voice of the reference person appears in a privileged manner. The recording functionality thus allows recordings from a few seconds to a few minutes.
[048] Il est également recommandé à la personne de référence de réaliser cet enregistrement de sa voix en plaçant le boîtier 1 contre sa poitrine. A l'occasion de l'enregistrement, le microphone 53 peut ainsi capter, en plus de la voix, un signal faible représentatif du rythme cardiaque de la personne de référence. [049] Après avoir enregistré des sons, le composant de traitement de son 52 effectue plusieurs traitements spécifiques sur ces sons. [048] It is also recommended that the reference person make this recording of his voice by placing the box 1 against his chest. During recording, the microphone 53 can thus pick up, in addition to the voice, a weak signal representative of the heart rate of the reference person. [049] After having recorded sounds, the sound processing component 52 performs several specific treatments on these sounds.
[050] Ainsi, le composant de traitement de son 52 effectue un traitement des sons enregistrés pour limiter le volume sonore maximum à une valeur déterminée. Ce traitement peut par exemple consister en une diminution du volume de l'ensemble de l'enregistrement, afin que l'ensemble de l'enregistrement présente un volume inférieur à la valeur prédéterminée. Il peut également consister, dans un autre mode de réalisation, en une réduction plus forte du volume d'enregistrement des portions d'enregistrement présentant un volume trop élevé. Dans ce cas, cette limitation du volume sonore maximum entraîne un lissage du volume sonore de l'enregistrement. [051] Le composant de traitement du son 52 effectue également, selon l'invention, un traitement des sons enregistrés pour réduire spécifiquement le volume des sons présentant les fréquences les plus hautes. Ce traitement peut consister en un filtrage fréquentiel destiné à limiter fortement les fréquences les plus hautes. Ainsi, dans le mode de réalisation représenté, ce traitement est effectué par un filtre passe-bas de premier ordre avec une fréquence de coupure de 400 Hz, qui atténue les fréquences supérieures à 400 Hz à raison de 20 dB par décade. [050] Thus, the sound processing component 52 performs processing of the recorded sounds to limit the maximum sound volume to a determined value. This processing may for example consist of reducing the volume of the entire recording, so that the entire recording has a volume lower than the predetermined value. It may also consist, in another embodiment, in a greater reduction in the recording volume of the recording portions having too high a volume. In this case, this limitation of the maximum sound volume results in a smoothing of the sound volume of the recording. [051] The sound processing component 52 also performs, according to the invention, a processing of the recorded sounds to specifically reduce the volume of the sounds having the highest frequencies. This processing may consist of frequency filtering intended to greatly limit the highest frequencies. Thus, in the embodiment shown, this processing is performed by a first order low pass filter with a cutoff frequency of 400 Hz, which attenuates frequencies above 400 Hz at a rate of 20 dB per decade.
[052] Un tel traitement du son permet, quand le son est ultérieurement diffusé à proximité d'un enfant nouveau-né, de limiter fortement l'impact, sur les oreilles du nouveau-né, de sons aigus ou stridents, tels qu'un éclat de voix aiguë, qui pourrait stresser le nouveau-né et/ou dégrader son audition, particulièrement dans le cas d'un nouveau-né prématuré dont les fonctions auditives ne sont pas complètement formées. [053] Dans l'état de diffusion sonore, la fonctionnalité de diffusion sonore du dispositif de traitement et de diffusion de sons est activée. Cette fonctionnalité de diffusion sonore est notamment mise en oeuvre par les composants électroniques qui ont pour fonctionnalité de diffuser des sons, et notamment par le haut-parleur 4 et le composant de traitement de son 52, sous le contrôle du microcontrôleur 51. [052] Such sound processing makes it possible, when the sound is subsequently broadcast near a newborn child, to greatly limit the impact, on the ears of the newborn, of high-pitched or strident sounds, such as a sharp burst of voice, which could stress the newborn and / or impair his hearing, particularly in the case of a premature newborn whose hearing functions are not fully formed. [053] In the sound broadcasting state, the sound broadcasting functionality of the sound processing and broadcasting device is activated. This sound broadcasting functionality is implemented in particular by the electronic components which have the function of broadcasting sounds, and in particular by the loudspeaker 4 and the sound processing component 52, under the control of the microcontroller 51.
[054] Le composant de traitement de son 52 peut ainsi diffuser, par l'intermédiaire du haut-parleur 4, des sons choisis. Avantageusement, cette fonctionnalité de diffusion sonore permet au dispositif de traitement et de diffusion de sons de diffuser des sons issus d'au moins deux pistes sonores distinctes. Au moins l'une de ces pistes est constituée par un son de voix, qui a été précédemment enregistré et traité par le dispositif de traitement et de diffusion de sons, dans le cadre de la fonctionnalité d'enregistrement. [054] The sound processing component 52 can thus broadcast, via the loudspeaker 4, selected sounds. Advantageously, this sound diffusion functionality allows the sound processing and distribution device to diffuse sounds originating from at least two distinct sound tracks. At least one of these tracks consists of a voice sound, which has been previously recorded and processed by the sound processing and broadcasting device, as part of the recording functionality.
[055] De préférence, une autre de ces pistes est constituée par un enregistrement de son à basse fréquence imitant la perception des battements de cœur. Cet enregistrement peut, dans un mode de réalisation avantageux, présenter un rythme et un volume sonore, éventuellement variable dans le temps, spécifiquement choisi pour obtenir un effet apaisant. Dans un mode de réalisation particulier, le rythme de cet enregistrement de son imitant la perception des battements de cœur peut être modulé, à partir d'une information liée au signal faible représentatif du rythme cardiaque de la personne de référence, qui a été capté précédemment par la fonctionnalité d'enregistrement. [055] Preferably, another of these tracks consists of a recording of low frequency sound imitating the perception of heartbeats. This recording can, in an advantageous embodiment, have a rhythm and a sound volume, possibly variable over time, specifically chosen to obtain a soothing effect. In a particular embodiment, the rhythm of this recording of sound imitating the perception of the heartbeats can be modulated, from information linked to the weak signal representative of the heart rate of the reference person, which was captured previously. by the recording functionality.
[056] Quand il met en œuvre cette fonctionnalité de diffusion sonore, le dispositif de traitement et de diffusion de sons peut mixer ces pistes sonores, ou diffuse l'une ou l'autre, en fonction d'une séquence prédéfinie. [056] When it implements this sound diffusion functionality, the sound processing and distribution device can mix these sound tracks, or broadcasts one or the other, according to a predefined sequence.
[057] Dans le mode de réalisation représenté, la séquence sonore pouvant être diffusée est la suivante : pendant une période de huit minutes, une piste sonore comprenant le son de la voix de la personne dont on veut simuler la présence est accompagnée d'une piste sonore de battements cardiaques. Ensuite, pendant une nouvelle période de deux minutes, le volume sonore de la piste comprenant le son de la voix diminue progressivement, alors que le son de battements cardiaques persiste. Enfin, pendant une dernière période de deux minutes, seul le son de battements cardiaques est diffusé. Une telle séquence sonore est favorable à l'apaisement progressif du nouveau-né. [057] In the embodiment shown, the sound sequence that can be broadcast is as follows: for a period of eight minutes, a sound track comprising the sound of the voice of the person whose presence is to be simulated is accompanied by a heartbeat sound track. Then for a new period of two minutes, the sound volume of the track including the sound of the voice gradually decreases, while the sound of heartbeats persists. Finally, during a final period of two minutes, only the sound of heartbeats is played. Such a sound sequence is favorable to the gradual appeasement of the newborn.
[058] Bien entendu, d'autres séquences sonores peuvent être diffusées pour s'adapter à des besoins différents. Les inventeurs ont réalisé des séquences sonores avec une période de huit à dix minutes d'une piste sonore comprenant le son de la voix de la personne dont on veut simuler la présence et accompagnée d'une piste sonore de battements cardiaques, une nouvelle période de huit à dix minutes avec une piste sonore comprenant de la musique et pendant une dernière période de deux minutes, seul le son de battements cardiaques est diffusé et diminue progressivement. [058] Of course, other sound sequences can be broadcast to adapt to different needs. The inventors have produced sound sequences with a period of eight to ten minutes of a sound track comprising the sound of the voice of the person whose presence is to be simulated and accompanied by a sound track of heartbeats, a new period of eight to ten minutes with a sound track including music and for a final period of two minutes only the sound of heartbeats is played and gradually decreases.
[059] La durée totale des séquences sonores diffusées par le procédé utilisant le dispositif selon l'invention est de préférence comprise entre 12 à 25 minutes de manière préférentielle 12 minutes. Une autre durée préférée est de 20 minutes, mais toutes les durées sont possibles avec le procédé et dispositif selon l'invention, bien que celles-ci ne dépassent ou n'égalent 25 minutes afin d'obtenir les résultats et effets techniques recherchés par les inventeurs. [059] The total duration of the sound sequences broadcast by the method using the device according to the invention is preferably between 12 to 25 minutes, preferably 12 minutes. Another preferred duration is 20 minutes, but all times are possible with the method and device according to the invention, although these do not exceed or equal 25 minutes in order to obtain the technical results and effects sought by the manufacturers. inventors.
[060] Il a été montré également dans un mode de réalisation préféré de remplacer dans la seconde séquence la piste sonore par une piste sonore musicale qui permet également de renforcer l'apaisement progressif du nouveau-né et ainsi d'avoir trois pistes différentes, mixés ensembles ou non. [060] It has also been shown in a preferred embodiment to replace in the second sequence the sound track by a musical sound track which also makes it possible to reinforce the progressive appeasement of the newborn and thus to have three different tracks, mixed together or not.
[061] Le procédé et le dispositif selon l'invention permet ainsi de diffuser simultanément ou non une piste sonore comprenant le son de la voix de la personne dont on veut simuler la présence, accompagné ou non d'une piste sonore de battements cardiaques, accompagné ou non d'une piste sonore comprenant une musique, puis une piste sonore comprenant une musique, comme une berceuse, des chuchotements, des fredonnements, des instruments de musiques, des sons d'animaux, tout ce que l'homme du métier connaît et utiliserait pour apaiser ou simuler la présence d'une personne de référence, et une piste sonore correspondant au cœur seul, ou encore à la voix de la personne de référence seule. [061] The method and the device according to the invention thus make it possible to broadcast simultaneously or not a sound track comprising the sound of the voice of the person whose presence is to be simulated, accompanied or not by a sound track of heartbeats, accompanied or not by a sound track comprising music, then a sound track comprising music, such as a lullaby, whispers, hums, musical instruments, animal sounds, everything that a person skilled in the art knows and would use to appease or simulate the presence of a reference person, and a sound track corresponding to the heart alone, or to the voice of the reference person alone.
[062] La musique peut être joué sur l'ensemble des périodes mais de préférence dans la seconde période de diffusion de la séquence sonore. [062] The music can be played over all the periods but preferably in the second period of the sound sequence.
[063] Il est également avantageux pour l'homme du métier dans un mode alternatif mais préféré de diminuer le volume sonore des pistes correspondants soit le son de la voix, soit le son de la musique, soit le son du cœur, soit simultanément ou non, immédiatement ou progressivement afin de favoriser l'apaisement et la simulation de présence. [063] It is also advantageous for those skilled in the art in an alternative mode but preferred to reduce the sound volume of the corresponding tracks either the sound of the voice, or the sound of music, or the sound of the heart, either simultaneously or no, immediately or gradually in order to promote appeasement and the simulation of presence.
[064] La combinaison de la voix, du battement de cœur et de la musique permet l'obtention d'un effet supérieur sur l'apaisement du nouveau-né et sur la simulation de présence. [064] The combination of voice, heartbeat and music results in a superior effect on the calming of the newborn and on the simulation of presence.
[065] De préférence, le dispositif est équipé d'une diode électroluminescente 54, qui peut donner des indications à l'utilisateur utilisant le dispositif de traitement et de diffusion de sons. Cette diode peut notamment, par exemple par son clignotement ou sa couleur, indiquer l'état dans lequel se trouve le dispositif, l’état de chargement de sa batterie, etc. [065] Preferably, the device is equipped with a light emitting diode 54, which can give indications to the user using the device for processing and broadcasting sounds. This diode can in particular, for example by its flashing or its color, indicate the state in which the device is located, the state of charge of its battery, etc.
[066] Au cours de la phase de diffusion sonore, cette diode électroluminescente peut également participer à la simulation en diffusant, de façon continue ou variable, une lumière d'intensité peu élevée, dans une plage de longueur d'onde choisie pour apaiser le nouveau-né. [066] During the sound diffusion phase, this light-emitting diode can also participate in the simulation by diffusing, continuously or variably, a light of low intensity, in a range of wavelength chosen to calm the patient. new born.
[067] De façon particulièrement avantageuse, les composants du dispositif de traitement et de diffusion de sons sont choisis pour ne pas émettre d'ondes électromagnétiques à des fréquences ou à des intensités susceptibles de perturber des équipements électroniques voisins. [067] Particularly advantageously, the components of the sound processing and diffusion device are chosen so as not to emit electromagnetic waves at frequencies or at intensities liable to disturb neighboring electronic equipment.
[068] L'utilisation du dispositif de traitement et de diffusion de sons dans un contexte hospitalier, à proximité d'équipements électroniques médicaux, interdit en effet tout risque de perturbation de ces équipements médicaux. Pour cela, le dispositif de traitement et de diffusion de sons selon le mode de réalisation représenté ne comprend en particulier aucune interface de communication radio. [069] Par ailleurs, la limitation des émissions d'ondes électromagnétiques permet d'éviter que le nouveau-né placé au voisinage du dispositif de traitement et de diffusion de sons ne reçoive de telles ondes, et donc d'éliminer tout risque que de telles ondes aient un impact préjudiciable sur sa santé. [070] De façon plus générale, le dispositif de traitement et de diffusion de sons est conçu de façon à être compatible avec une utilisation dans un milieu médical ou hospitalier. Ainsi, par exemple, les matériaux utilisés pour la fabrication du dispositif, et les formes de ce dispositif, sont choisis de façon à respecter les exigences d'hygiène nécessaires dans de tels milieux. [071] La figure 2 représente de façon schématique les étapes d'un procédé de diffusion de son destiné à des nouveau-nés. [068] The use of the device for processing and broadcasting sounds in a hospital context, near medical electronic equipment, in fact prohibits any risk of disturbance of this medical equipment. For this, the device for processing and broadcasting sounds according to the embodiment shown in particular does not include any radio communication interface. [069] Furthermore, the limitation of the emissions of electromagnetic waves makes it possible to prevent the newborn placed in the vicinity of the device for processing and broadcasting sounds from receiving such waves, and therefore to eliminate any risk of such waves have a detrimental impact on his health. [070] More generally, the device for processing and broadcasting sounds is designed so as to be compatible with use in a medical or hospital environment. Thus, for example, the materials used for the manufacture of the device, and the shapes of this device, are chosen so as to meet the hygiene requirements necessary in such environments. [071] FIG. 2 schematically represents the steps of a method of broadcasting sound intended for newborns.
[072] Ce procédé comporte une étape 61 d'enregistrement d'une voix, plus précisément de la voix de la personne de référence. Cette étape d'enregistrement 61 est suivie de deux étapes de traitement du son. Une première étape de traitement du son 62 consiste à ajuster le volume de l'enregistrement pour que son volume maximal ne dépasse pas une valeur déterminée. Une seconde étape de traitement du son 63, de réduction des hautes fréquences, consiste à réduire ou à supprimer, sur cet enregistrement, les composantes du son dont la fréquence est plus élevée qu'une fréquence déterminée, dans le spectre des fréquences audibles. [073] Ces deux étapes de traitement du son 62 et 63 peuvent être réalisées simultanément ou successivement. Si elles sont réalisées successivement, la première étape de traitement du son 62 peut indifféremment être réalisée avant ou après la seconde étape de traitement du son 63. [072] This method comprises a step 61 of recording a voice, more precisely the voice of the reference person. This recording step 61 is followed by two sound processing steps. A first sound processing step 62 consists in adjusting the volume of the recording so that its maximum volume does not exceed a determined value. A second sound processing step 63, of reducing the high frequencies, consists in reducing or eliminating, on this recording, the sound components whose frequency is higher than a determined frequency, in the spectrum of audible frequencies. [073] These two sound processing steps 62 and 63 can be carried out simultaneously or successively. If they are carried out successively, the first sound processing step 62 can equally well be carried out before or after the second sound processing step 63.
[074] Enfin, ce procédé comporte une étape 64 de diffusion sonore, au cours de laquelle l'enregistrement précédemment effectué et traité est diffusé, préférentiellement mixé avec un autre enregistrement comprenant un son à basse fréquence imitant la perception des battements du cœur. [074] Finally, this method comprises a sound broadcasting step 64, during which the recording previously made and processed is broadcast, preferably mixed with another recording comprising a low frequency sound imitating the perception of the beating of the heart.
