Definitions

  • This invention relates to a method of adapting a hearing aid having at least one input transducer, a signal processing unit, and an output transducer using a morphometric feature. Furthermore, the invention relates to a hearing aid which can be adapted to the hearing aid wearer as a function of a morphometric feature.
  • Modern hearing aids can be adapted to the individual needs of their wearers.
  • the sound pressure is u.a. also dependent on the size and geometry of the ear canal. This requires a complex and regular adaptation, especially in children, since their auditory canal changes continuously due to growth processes.
  • ear-specific and frequency-specific hearing thresholds by measuring methods on the patient, and also to measure the acoustic properties of the auditory canal in order to be able to frequency-dependently convert a respective hearing threshold to a respective sound pressure level in the auditory canal.
  • This can be done, for example, with the aid of a device for adapting the hearing device, wherein the hearing device is connected to a coupler, by means of which the sound pressure level, which is output by the hearing aid, can be determined frequency-dependent.
  • the coupler has a standardized volume, which is the volume of the ear canal of the hearing aid wearer should correspond, for example, 2cm 3 .
  • the coupler volume differs, especially in children, from the actual volume of the ear canal of the hearing aid wearer, and because the geometry of the ear canal also plays a role, it is necessary to adapt the fitting of the hearing aid to the wearer with the aid of a fitting parameter.
  • RECD value real-ear-to-coupler difference
  • the RECD value or other appropriate fitting parameters such as the real-ear-unaided-gain (REUG) value
  • REUG real-ear-unaided-gain
  • the RECD values change with age (cf. Bagatto M, Moodie S, Scollie S, Seewald R, Moodie S, Pumford J, Liu KP., Clinical protocols for hearing instrument fitting in the Desired Sensation Level method. Trends Amplif. 2005; 9 (4): 199-226 ).
  • age-dependent adaptation can be dispensed with the time-consuming measurement at the child's ear.
  • age-related adaptation is not very accurate and disregards individual differences within an age group.
  • This object is achieved by a method according to claim 1, an arrangement for carrying out the method according to claim 10 and a hearing aid according to claim 11.
  • the invention is based on the finding that there are morphometric features or parameters of the hearing device wearer, which is a good adaptation of the hearing aid to the individual needs of the carrier.
  • the adaptation of the adaptable parameter as a function of the morphometric feature preferably takes place by assigning an instruction for adapting the adaptable parameter of the hearing device to the morphometric feature by the device for adapting the hearing device and adapting the adjustable parameter by the signal processing device of the hearing device for individual adaptation of the hearing device the hearing aid wearer.
  • a morphometric feature is a shape related feature and includes all features measurable on the shape, eg body size, distance measurements such as head diameter or eye relief, body or body part volume, area sizes and weight.
  • BMI body mass (in kg) / body size 2 ( in cm 2 )
  • an age-dependent and / or growth-dependent morphometric feature is preferred, ie, a morphometric feature that varies depending on the age and / or growth of the wearer.
  • Preferred morphometric features are body size, body weight, head circumference, and head diameter, especially the fronto-occipetal head diameter (measured from the forehead to the back of the skull) and the biparietal head diameter
  • the term "transmitting the morphometric feature” means inputting or transmitting the morphometric feature into the device for adjusting the hearing aid. It is possible to detect the morphometric feature by a measuring device, e.g. a scale, a gauge, a fair bar, a scanner or the like and then enter the morphometric feature as a measurable manually in the device for adjusting the hearing aid or to transfer directly from the measuring device to the adapter in the form of a signal.
  • a measuring device e.g. a scale, a gauge, a fair bar, a scanner or the like
  • an instruction for adaptation means an instruction, a calculation instruction, an algorithm, a factor, e.g. an amplification factor, a frequency characteristic, or in the broadest sense, information that can be used by the signal processing unit to match the gain characteristics to the needs of the hearing aid wearer.
  • the device for adapting the hearing device is included in the signal processing device.
  • An "adaptive parameter” is a parameter by means of which the acoustic properties of the hearing aid can be adapted to the needs of the hearing aid wearer, e.g. a gain, in particular a frequency-specific gain, a frequency characteristic, a sound pressure level, in particular a frequency-specific sound pressure level, a control time, a noise suppression, etc.
  • the adjustable parameter comprises a sound pressure level, more preferably a frequency-dependent sound pressure level.
  • the transmission of the morphometric feature or the instruction for adapting the at least one adjustable parameter to the hearing aid is carried out by wireless transmission.
  • the morphometric feature is associated with an instruction to adjust the hearing aid and transmitted wirelessly to the hearing aid.
  • the method uses a digital signal processing device.
  • the adaptation can be carried out by supporting a corresponding software.
  • the invention further relates to a hearing aid system, comprising a hearing aid unit with at least one input transducer, a signal processing device and an output transducer, characterized in that the signal processing device has an input facility for inputting a morphometric feature and adjusts at least one adjustable parameter in response to the input of the morphometric feature.
  • information relating to the morphometric feature is transmitted to the signal processing device and the adaptation takes place completely in the hearing device.
  • the invention relates to an arrangement for carrying out the method according to the invention, comprising a hearing aid with at least one electroacoustic input transducer, a signal processing device and an electroacoustic output transducer and means for adjusting the hearing aid with an input option for inputting information regarding a morphometric feature of a hearing aid wearer.
  • FIG. 1 it is customary to carry out a measurement 1 (real ear measurement, REM) on the ear 3 of a hearing device wearer and to transmit the values obtained to a device 5 for adapting a hearing device 7 to the hearing aid to adapt to the individual needs or anatomical conditions of the wearer.
  • a measurement 1 real ear measurement, REM
  • a morphometric characteristic of the carrier is detected, as shown here For example, the biparietal head diameter, and transmitted to a device 5 for adjusting the hearing aid 7.
  • the detected morphometric feature is converted to a hearing aid fitting instruction.
  • This can e.g. be done by having the morphometric feature, e.g. the biparietal head diameter is correlated with a RECD value obtained by comparison with reference RECD values obtained experimentally in subjects by SEM measurements and correlated with the measured value of the corresponding morphometric feature of the same subject, and eg stored in a database.
