The present investigation was designed to observe the reduction of stuttering when the acoustic environment of the speaker was altered.The subjects were 8 male stutterers with range in age from 11 to 22 years, and 4 normal young adults; 2 males and 2 females. As masking noises, song, orchestra, news and white noise were selected. Each masking noise was presented at 90dB binaurally and monaurally during oral reading of a set of word passages to observe the stuttering under masking noise. The results of this experiment indicate that masking noises with song and orchestra bring about a marked reduction in the severity of stuttering and news has a little effect. But the inhibition was less effective with white noise.The binaural masking is more effective than the monaural one for the reduction of stuttering.
