ABSTRACT
OBJECTIVE:
Speech-in-noise tests are widely used in hearing diagnostics but typically without reverberation, although reverberation is an inextricable part of everyday listening conditions. To support the development of more real-life-like test paradigms, the objective of this study was to explore how spatially reproduced reverberation affects speech recognition thresholds in normal-hearing and hearing-impaired listeners.DESIGN:
Thresholds were measured with a Finnish speech-in-noise test without reverberation and with two test conditions with reverberation times of â¼0.9 and 1.8 s. Reverberant conditions were produced with a multichannel auralisation technique not used before in this context. STUDY SAMPLE Thirty-four normal-hearing and 14 hearing-impaired listeners participated in this study. Five people were tested with and without hearing aids.RESULTS:
No significant differences between test conditions were found for the normal-hearing listeners. Results for the hearing-impaired listeners indicated better performance for the 0.9 s reverberation time compared to the reference and the 1.8 s conditions. Benefit from hearing aid use varied between individuals; for one person, an advantage was observed only with reverberation.CONCLUSIONS:
Auralisations may offer information on speech recognition performance that is not obtained with a test without reverberation. However, more complex stimuli and/or higher signal-to-noise ratios should be used in the future.Palavras-chave
