[Band filtration of the speech signal: speech perception in health status and in sensorineural hearing loss].
We made band speech filtration by dividing the spectrum into the frequency bands 50, 100, 200, 500 and 1000 Hz with following removal of the even or odd bands. We found that audibility of speech in all the examinees with normal hearing was 100% irrespective of the band width and composition of the speech signal (a total of the even or odd bands). Audibility of speech composed of odd bands 100 Hz width improved by 4 to 16% in patients with neurosensory hypoacusis.
