摘要：Sensorineural hearing impairment causes widening of auditory filters. Widening of auditory filter leads to spectral masking. Spectral masking leads to degraded speech perception as there is masking of frequency components by adjacent frequency components. Earlier studies have revealed, frequency masking can be reduced by binaural dichotic presentation, using critical band filter bank. In this scheme speech signal from odd numbered critical band filters is presented to one ear and even numbered to other ear. Studies have shown that this scheme helps in reducing the effect of spectral masking for persons having moderate bilateral sensorineural hearing impairment. This paper presents the study of various techniques used for the improvement of sensorineural hearing impairment.
