| Research Abstract |
The purpose of this study is to examine the effect of reverberation on speech perception for the efficient hearing. This study revealed that(1) compared with non-reverberant speech, reverberant speech are perceptible as 5-6 dB louder,(2) in case the reverberation is less than 0.2 seconds, word intelligibility of reverberant speech is comparable to that of non-reverberant speech, and(3) subtle differences in word indelibility can be detected by degenerating speech signal with the low-pass filter.
