Description

До насто щего времени считалось, что в тех случа х, когда у глухого уха рассто ние между порогом слышимости и болевым порогом меньше диапазона громкости речи, разбираемость речи, усиленной слуховым протезом , будет очень низкой, так как часть звуков будет неслышимой или же, при большем усилении часть звуков будет вызывать болевые ощущени . Поэтому при большой потере слуха применение усилительных протезов встречало затруднени  в виду возможного нанесени  вреда из-за частого возникновени  болевых ощущений и св занных с этим изменений в слуховом аппарате. Дл  устранени  этого недостатка в предлагаемом слуховом протезе использован известный уже по своему применению в радиотехнике и электроакустике сжиматель динамического диапазона громкости, который помещен между микрофоном и уси.чите .зем.Until now, it was considered that in those cases when the deaf ear had a distance between the hearing threshold and the pain threshold less than the loudness range of speech, the speech parity enhanced by the hearing prosthesis would be very low, as some of the sounds would be inaudible or more amplification of the sounds will cause pain. Therefore, with a large loss of hearing, the use of reinforcing prostheses was difficult because of the possible harm due to the frequent occurrence of pain and the associated changes in the hearing aid. To eliminate this drawback in the proposed auditory prosthesis, a dynamic volume range compresser, already known for its use in radio engineering and electroacoustics, is used, which is placed between the microphone and the speaker.

На чертеже изображена схема слухового протеза. Предлагаемый слуховой протез включает в себе микрофон /, усилитель 5, телефон 4 и расположенный между микрофоном и усилителел сжиматель 2. Таким образом , путем соответствующего сжати  имеетс  в виду достигнуть возможности уложить нужный диапазон в любое рассто ние между порогом слышимости и болевым порогом .The drawing shows a diagram of the auditory prosthesis. The proposed hearing prosthesis includes a microphone /, amplifier 5, telephone 4 and compressor 2 located between the microphone and the amplifier. Thus, by appropriate compression, it is intended to achieve the ability to fit the desired range to any distance between the hearing threshold and the pain threshold.

Предмет изобретени .The subject matter of the invention.

Слуховой протез с применением микрофона, усилител  и телефона, отличающийс  тем, что, с целью расположени  звукового диапазона между порогом слыщимости и болевым порогом, применен известный сжиматель динамического диапазона громкости, включенный между микрофоном и усилителем.An acoustic prosthesis using a microphone, an amplifier and a telephone, characterized in that, in order to locate the sound range between the hearing threshold and the pain threshold, the well-known dynamic range compactor is used, connected between the microphone and the amplifier.
