Definitions

  • the invention relates to a hearing aid and a method for simulating a hearing loss.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids, hearing aids with external earphones and in-the-ear hearing aids, e.g. also provided Concha hearing aids or channel hearing aids.
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit.
  • FIG. 1 illustrated by the example of a behind-the-ear hearing aid 1.
  • a hearing aid housing 2 for carrying behind the ear one or more microphones 3 are incorporated for receiving the sound from the environment.
  • a signal processing unit 4 which is also integrated in the hearing aid housing 2, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 4 is transmitted to a loudspeaker or receiver 5, which outputs an acoustic signal.
  • the sound is over one Sound tube 7, which is fixed with an earmold 8 in the ear canal, transmitted to the eardrum of the hearing aid wearer.
  • the power supply of the hearing device 1 and in particular that of the signal processing unit 4 is effected by a battery 6 likewise integrated into the hearing device housing 2.
  • hearing loss simulation can also be used in hearing aid development.
  • Testing hearing aid algorithms is an important part of any hearing aid development.
  • clinical trials are usually conducted in which hearing-impaired patients with or without hearing aids participate as subjects.
  • the details of the subjects are, however, often of various subjective factors, such.
  • attitude towards technology in general, age, desire, time, etc. dependent which can significantly affect the results.
  • the results are more valid or reproducible and thus more valuable for the decision for or against a particular algorithm or further development.
  • Normal hearing experts / test persons can by simulating a Hearing loss.
  • the evaluation of the hearing aid algorithms by an expert.
  • there is the possibility that the same expert can judge a hearing aid algorithm with different hearing losses. This has the advantage of being able to minimize the variance that can be minimized by assessing different subjects, as found in conventional clinical trials.
  • a hearing loss simulation may also be useful for a hearing aid professional hearing a normal hearing.
  • An adjustment of hearing aids is either referred to mean values, or the hearing aid wearer is used as a "measuring instrument".
  • this "meter” is often very inaccurate, so the adjustment is either a very lengthy process or, in principle, results in a wrong rather than an optimized setting. This is especially the case of particularly complex hearing losses of the case, such.
  • a simulation of hearing loss may be used to have the acoustician customize the hearing aid for the hearing impaired. To do this, the acoustician uses the simulation of hearing loss to experience the sensation of the hearing-impaired, which is then to be compensated for via the correct hearing aid setting.
  • the DE 101 10 945 A1 therefore discloses a simulation of the hearing loss of a hearing-impaired person.
  • the hearing of the hard of hearing is detected.
  • test signals are adapted to the thus determined hearing and presented to a normal hearing via speakers. This gives him a largely realistic impression of the hearing loss of the hard of hearing.
  • the arrangement of the loudspeakers and the acoustic properties of the room in which the loudspeakers are arranged play a not insignificant role in the simulation.
  • the invention claims a hearing aid with a first earpiece for emitting a first sound signal and with a means for simulating a hearing loss, wherein the means changes the first sound signal emitted by the first earpiece according to the hearing loss. That is, the means modifies or distortes or transforms the first sound signal emitted by the listener such that it is perceived by a normal hearing person as having the hearing loss of a hearing impaired person.
  • the hearing loss may correspond to the actually determined hearing loss of a hearing device wearer.
  • the invention offers the advantage that hearing aid experts, hearing aid acousticians or accompanying persons of the hard of hearing have the perception of a deaf person in the evaluation of hearing aid algorithms or in the hearing aid fitting.
  • the hearing loss to be simulated can be measured, determined or calculated.
  • the means can attenuate the first sound signal and / or distort its frequency. This can be used to simulate all types of hearing loss.
  • the means may be arranged in a sound tube and / or in an otoplastic. This makes it easy to simulate hearing loss.
  • the means may be formed purely mechanically or purely electrically. That is, the attenuation and or frequency distortion of the first sound signal occurs on mechanical pasture or with electrical components.
  • the means may comprise a second signal processing unit which modifies or transforms the first sound signal.
  • the means may comprise a second microphone and a second receiver, the second microphone receiving the first sound signal emitted by the first listener and the second listener outputting the first sound signal, which is changed by the second signal processing, as the second sound signal.
  • the hearing loss simulation is performed by the second signal processing unit.
  • the invention also claims a method of simulating hearing loss by altering a first sound signal emitted by a hearing aid in accordance with hearing loss.
  • the first sound signal can be output by a first listener.
  • the change of the sound signal can take place mechanically and / or electrically.
  • the first sound signal emitted by the first listener can be recorded by a second microphone, and the first sound signal modified by signal processing can be output as the second sound signal by a second listener.
  • FIG. 2 shows a behind-the-ear hearing aid 10 with a hearing aid housing 16.
  • a sound tube 14 is connected at one end to the hearing aid housing 16.
  • a first microphone 11 in the hearing aid housing 16 receives ambient sound and converts it into an electrical signal This is changed in a first signal processing unit 12 in the hearing aid housing 16 and amplified and delivered to a first handset 13 in the hearing aid housing 16.
  • the first receiver 13 converts the thus amplified electrical signal into a first sound signal S1 and delivers it into the sound tube 14.
  • a means 20 for simulating the hearing loss of the hearing-impaired person is arranged in the sound tube 14.
  • the means 20 attenuates broadband or frequency-dependent the first sound signal S1 according to the hearing loss of the hearing impaired.
  • the means 20 is constructed mechanically and comprises, for example, a plastic plug. After the means 20 thus a second sound signal S2 is emitted, which also emerges from the earmold 15. The second sound signal S2 thus results from the first sound signal S1 of the first listener 13 attenuated by the loss of sensitivity caused by the mechanical damping of the means 20. A normal hearing would therefore perceive the second sound signal S2 as a hearing impaired with a broadband or frequency-dependent loss of sensitivity.
  • FIG. 3 shows a behind-the-ear hearing aid 10 with a hearing aid housing 16.
  • a sound tube 14 is provided with one end the hearing aid housing 16 connected.
  • An earmold 15 is seated at its other end.
  • a first earphone 13 emits through the sound tube 14 a first sound signal S1 recorded by a first microphone 11 and amplified and amplified by a first signal processing unit 12 into the sound tube 14.
  • a means 20 for simulating the hearing loss of the hearing-impaired person is arranged in the sound tube 14.
  • the means 20 attenuates broadband or frequency-dependent the first sound signal S1 according to the hearing of the hearing impaired.
  • the means 20 comprises a second microphone 21, which receives the first sound signal S1, a second signal processing unit 22, which changes the first sound signal S1 corresponding to the hearing loss to be simulated by the hearing impaired person, and a second listener 23, which converts the signal thus modified as the second sound signal S2 in FIG emits the sound tube 14.
  • the second signal processing unit 22 can simulate all types of hearing loss using a variety of parameters.
  • the means 20 may alternatively be arranged in the earmold 15.
  • a normal hearing expert who is to judge a hearing aid algorithm for example, can test it in everyday life, his perception corresponding to that of a hearing impaired person whose hearing loss is simulated by the means 20.
  • the advantage of this is that a normal hearing expert can test the hearing aids as a deaf person in everyday life and judge his perception.
  • a hearing care professional with his hard-of-hearing client can seek out the hearing situation that he would like to have improved through his hearing aid.
  • the hearing care professional now the opportunity to experience the world with the ears of his customers or with his hearing loss and the hearing aid 10 set so that an optimal sensation by the hearing care professional and not by a "lay" (ie the hearing aid wearer) can be achieved ,
  • the adjustment is therefore much faster and more targeted due to the expertise and experience of the acoustician.
  • This can additionally bring advantages in the adjustment of the hearing aid from an audiological point of view, as these are often neglected due to spontaneous acceptance reasons.
  • the hearing care professional would, for example, adjust the hearing aid to the simulated hearing loss so that maximum speech understanding is achieved. This is a setting that the hearing aid wearer would very often refuse because of too sharp a perception.
  • frequency compression or transformation
  • frequency components are transformed into frequency ranges in which a hearing perception can still be guaranteed.
  • This adaptation requires special care, since an incorrect setting of the hearing aid would mean a false "reprogramming" of the hearing aid wearer's brain. Namely, this "reprogramming" is necessary because the deaf person using such frequency compression learns to hear and understand with the new frequency information.
