The utility model belongs to medicine, in particular to audiology, and can be used in diagnostics to monitor the functional state of the human middle ear system. The hearing aid has a sound processor consisting of a housing with a microphone, a microphone amplifier, a compressor, a hardware amplifier, a bandpass filter, a programmable amplifier, modulator, and a ring focusing grid of piezoelectric elements. The grid, contacting the air in the external auditory canal, transmits the speech signal (mechanical vibrations) to a round or oval window of the cochlea of the human’s inner ear, allowing to adjust the sound quality of the hearing aid.
The patent is implemented in the innovative technologies:
- Broadband acoustic ear echo spectrometer and new effective program of universal audiological screening of newborns
