Abstract

OBJECTIVE

The purpose of this study is to assess the individual effect of reverberation and noise, as well as their combined effect, on speech intelligibility by cochlear implant (CI) users.

DESIGN

Sentence stimuli corrupted by reverberation, noise, and reverberation + noise are presented to 11 CI listeners for word identification. They are tested in two reverberation conditions (T60 = 0.6 s, 0.8 s), two noise conditions (SNR = 5 dB, 10 dB), and four reverberation + noise conditions.

STUDY SAMPLE

Eleven CI users participated.

RESULTS

Results indicated that reverberation degrades speech intelligibility to a greater extent than additive noise (speech-shaped noise), at least for the SNR levels tested. The combined effects were greater than those introduced by either reverberation or noise alone.

CONCLUSIONS

The effect of reverberation on speech intelligibility by CI users was found to be larger than that by noise. The results from the present study highlight the importance of testing CI users in reverberant conditions, since testing in noise-alone conditions might underestimate the difficulties they experience in their daily lives where reverberation and noise often coexist.

摘要

目的

本研究旨在评估混响和噪声对人工耳蜗（CI）使用者言语可懂度的单独影响，以及它们的综合影响。

设计

为 11 名 CI 使用者呈现受混响、噪声和混响+噪声干扰的句子刺激，以进行单词识别测试。他们在两种混响条件（T60 = 0.6s、0.8s）、两种噪声条件（SNR = 5dB、10dB）和四种混响+噪声条件下进行测试。

研究样本

11 名 CI 使用者参与了研究。

结果

结果表明，混响对言语可懂度的影响大于加性噪声（语音噪声），至少在测试的 SNR 水平下是如此。与单独的混响或噪声相比，混合效应更大。

结论

本研究发现，混响对 CI 使用者言语可懂度的影响大于噪声。本研究的结果强调了在混响条件下测试 CI 使用者的重要性，因为在噪声环境下进行测试可能会低估他们在日常生活中遇到的困难，因为混响和噪声经常同时存在。
