Definitions
- a device that enables deaf people to perceive sound
- the invention involves a device that enables deaf people to perceive sound. In particular, it enables deaf children to hear their own vocal utterances. It thus provides the auditory feedback essential to learning how to produce intelligible speech.
- a sensorineural deaf child may be enabled to hear sound with a cochlear implant.
- the quality of the sound transmitted to a deaf person via a cochlear implant lacks the clarity enjoyed by people with normal hearing ability.
- Implantation requires surgery by a specialist in this field. The surgery is followed by an extended period of speech therapy to accustom the recipient to the sound characteristics of the implant. The cost of the implants is very high (US$30,000 - 50,000).
- the primary advantage of mis prosthetic approach is the mobility it offers to the recipient.
- An example of electro-tactile stimulation is the Tickle-Talker. This device relies on electric stimulation of the fingers of the hand. The user must learn to associate the electric stimulations with different frequency ranges of sound in his/her surroundings. The same is true of current vibro-tactile devices.
- Neither type of tactile hearing aid converts the analog auditory input into a form that a sensorineural deaf person can perceive in the brain as sound.
- the present invention is a device that enables deaf people to perceive sound which comprises: a microphone configured to receive the analog audio signal from the user and from his or her teacher and output the said analog audio signal; an audio signal processing circuit configured to receive the said analog audio signal and covert it into a time domain amplified signal; at least two piezoelectric transducers configured to receive said time domain amplified signal and by means of which said piezoelectric disks create minute vibrations of the user's skin, which stimulate the Pacinian corpuscles in the skin;
- the nerve impulses from the Pacinian corpuscles are transmitted to the brain. As the impulses are in the form recognized by the brain as sound, they are perceived by the user as sound.
- said time domain amplified signal may be modulated onto a carrier wave.
- the dielectric constant of said piezoelectric transducers is the same as human skin.
- the transducers are in the shape of a disk, a ball or a cup.
- Said piezoelectric transducers are made of zirconium titanate ceramic.
- the device enables deaf people to perceive sound and is used in speech training of a sensorineural deaf child.
- the present invention enables deaf children to hear their own vocal utterances and thus provides the auditory feedback essential to learning how to produce intelligible speech.
- deaf children can learn to communicate verbally with the hearing population using a low cost alternative to the cochlear implant.
- Figure 1 illustrates the essential components of the present invention
- Figure 2 is a circuit block diagram of the present invention
- Figure 3 is a detailed example of an example circuit used in an embodiment of the present invention.
- Table 1 lists the values of components used in the example circuit. Description of Preferred Embodiments
- a device that enables deaf people to perceive sound comprises a microphone 1, an audio signal processing circuit 2 and at least two piezoelectric transducers 3.
- the microphone 1 receives the analog audio information from the user and from his or her teacher. It outputs an analog signal to an audio signal processing circuitry 2.
- the audio signal processing circuitry 2 converts the incoming non-linear acoustic information into a time domain amplified signal.
- audio signal processing circuitry 2 processes the incoming complex non-linear waveform to remove the frequency component and leave only the time rate of change information contained in the analog signal. Thus, the frequency domain is suppressed and the time rate of change of the incoming signal is amplified.
- the amplified signal may be modulated onto a carrier wave.
- Methods for accomplishing this conversion are known in the art (see US Patent Nos. 3,647,970; 4,545,065; 4,819,199; 4,860,356).
- Figure 3 illustrates a representative example of a signal processing circuit.
- This signal is then transmitted to piezoelectric transducers 3 which create minute vibrations of the user's skin stimulating the Pacinian corpuscles in the skin.
- Said transducers 3 are made of zirconium titanate ceramic and the dielectric constant of said transducers 3 is the same as human skin.
- Said transducers 3, usually two in number and usually disk-shaped, may be placed anywhere on the bare skin of the listener.
- the transducers 3 create minute vibrations of the skin which stimulate the Pacinian corpuscles in the skin.
- the transducers may be in the shape of a ball or a cup.
- the Pacinian corpuscle is a nerve ending in the skin that transforms mechanical vibrations or pressures into nerve impulses.
- Research by Fernando Grandori and Antonio Pedotti of Milan, Italy demonstrated that the Pacinian corpuscle can react to very high frequencies, and responds best to a square wave stimulus.
- rate of change is more important than the amplitude of the pressure applied to the corpuscle. This skin receptor detects time significance first, and pressure significance secondly.
- the nerve impulses from the Pacinian corpuscles are transmitted to the brain.
- the impulses are in the form recognized by the brain as sound, they are perceived by the user as sound.
- the present invention receives analog auditory information and delivers it to the brain in the form required for perception of sound. It enables children with sensorineural deafness to hear their own vocalizations (and those of their teachers) and, thus, to learn to speak.

Abstract
L'invention porte sur un dispositif qui permet à des personnes sourdes de percevoir un son. Ce dispositif comprend : un microphone configuré pour recevoir le signal audio analogique en provenance de l'utilisateur et de son professeur et émettre ledit signal audio analogique ; un circuit de traitement de signal audio pour convertir ledit signal audio analogique en un signal amplifié de domaine temporel ; au moins deux transducteurs piézoélectriques configurés pour recevoir ledit signal amplifié de domaine temporel et au moyen duquel lesdits transducteurs piézoélectriques créent de minuscules vibrations de la peau de l'utilisateur qui stimulent les corpuscules de Pacini dans la peau. Les influx nerveux issus des corpuscules de Pacini sont transmis au cerveau et reconnu par le cerveau en tant que son. Ceci permet à des enfants sourds d'entendre leurs propres paroles vocales et fournit ainsi la rétroaction auditive essentielle pour l'apprentissage de la façon de produire une parole intelligible.
