Abstract

Some hearing-aid users experience listening difficulty in certain environments, e. g., related to reverberation, but no standard way currently exists to evaluate hearing-aid fit adversely affected by reverberation.<br>We produced speech materials with different reverberation times that mimicked the actual listening environment. Those with normal hearing and with impaired hearing took listening tests using these materials wearing a hearing aid in a sound-proof booth. Listening tests were also done in an actual environment.<br>Results showed that increasing reverberation times of two-syllable words decreased in the percentages of correct answers in the hearing-impaired, as also occurred in a real environment.<br>These findings suggest that using speech materials with different reverberation times enables hearing-aid to be evaluated in relation to reverberation.
