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. A technique for human hearing diagnosis, which uses the acoustic influence on the middle human ear signal at different frequencies. For both ears, the equivalent volume of the middle ear and the volume of the external auditory canal at the standard probing signal frequency of 226 Hz and other frequencies (660 Hz, 800 Hz, 1000 Hz) is determined, the lower resonant frequency is also determined, and the formula for the middle ear norm parameter i.e. the middle ear norm factor A is calculated.
The patent is implemented in the innovative technologies:
- Broadband acoustic ear echo spectrometer and new effective program of universal audiological screening of newborns
