hearing aid for whole tone type difficulty in hearing and nervous sensing tone type difficulty in hearing

摘要

The damage to biological conduction organizations of persons with disabilities around the sound-induced hearing loss and damage caused to the physical conduction of sound institutions In the case of disability caused neurological sense of hearing loss or deafness are two of the complex is used in combination with possible before the hearing loss and neural hearing loss sensitive Combine hearing started. The present invention provides a hearing aid comprising a speaker a signal amplified by the amplifier and amplifier unit for the microphone, amplifying the electrical signals input from a microphone for a speech signal to the electrical signaling converts a voice signal, a microphone and it is connected between the amplification unit, a condenser (C1) and a variable resistor (VR1) connected and configured in parallel, low-pass filter unit for filtering the low-frequency signal; It is connected between the amplifier unit and the speakers capacitor (C4) and a variable resistance (VR2) connected in series and configured for filtering the high-frequency filter unit a high-frequency signal; And to a variable resistor (VR3) further comprising a volume controller configured to control the size of the signal to be amplified is connected to the amplifier unit.
