Speech recognition was assessed under three levels of room reverberation, each in quiet and noise, for subjects with varying amounts of sensorineural hearing impairment. The three acoustic environments were: sound suite, reverberant room with a reverberation time (T) = 0.54 s and reverberant room with T = 1.55 s. Three groups of subjects were utilized: normal hearing, mild sensorineural hearing impairment and moderate-to-severe sensorineural hearing impairment. Speech recognition ability for each of the three groups of subjects significantly differed from the other two groups for each of the three reverberant conditions. The detrimental influences of noise and reverberation increased with the magnitude of hearing impairment. In addition, there was an interaction between noise and room reverberation, where the detrimental effects of room reverberation were compounded by the addition of noise.
针对不同程度感音神经性听力损失的受试者，在三种房间混响水平下评估语音识别能力，每种混响水平又分为安静环境和噪声环境。三种声学环境分别为：消声室、混响时间（T）=0.54秒的混响室和T = 1.55秒的混响室。使用了三组受试者：听力正常、轻度感音神经性听力损失和中度至重度感音神经性听力损失。在三种混响条件下，三组受试者各自的语音识别能力均与其他两组存在显著差异。噪声和混响的有害影响随听力损失程度的增加而增大。此外，噪声和房间混响之间存在相互作用，即增加噪声会使房间混响的有害影响加剧。
