METHOD OF PROCESSING AN ACOUSTIC SIGNAL, AND A HEARING INSTRUMENT
Methodology is provided for suppressing room reverberation by calculating hearing aid gain based on a room impulse attenuation measure (the maximum negative slope of the logarithm of the input signal power as a function of time in multiple frequency bands) and signal-to-reverberation-noise ratio.

| Zusammenfassung: | Methodology is provided for suppressing room reverberation by calculating hearing aid gain based on a room impulse attenuation measure (the maximum negative slope of the logarithm of the input signal power as a function of time in multiple frequency bands) and signal-to-reverberation-noise ratio. Gain monotonically increases with signal-to-reverberation-noise
ratio. Maximum gain is applied if the difference between the acoustic input signal power and the acoustic input signal power delayed is positive.-DAP |
