The Words-in-Noise (WIN) test uses monosyllabic words in seven signal-to-noise ratios of multitalker babble (MTB) to evaluate the ability of individuals to understand speech in background noise. The purpose of this study was to evaluate the criterion validity of the WIN by comparing recognition performances under MTB and speech-spectrum noise (SSN) using listeners with normal hearing and listeners with hearing loss. The MTB and SSN had identical rms and similar spectra but different amplitude-modulation characteristics. The performances by the listeners with normal hearing, which were 2 dB better in MTB than in SSN, were about 10 dB better than the performances by the listeners with hearing loss, which were about 0.5 dB better in MTB with 56% of the listeners better in MTB and 40% better in SSN. The slopes of the functions for the normal-hearing listeners (8-9%/dB) were steeper than the functions for the listeners with hearing loss (5-6%/dB). The data indicate that the WIN has good criterion validity.
噪声中的单词（WIN）测试使用七个信噪比的多说话者嘈杂声（MTB）中的单音节词来评估个体在背景噪声中理解言语的能力。本研究的目的是通过比较正常听力的听众和听力损失的听众在MTB和语音频谱噪声（SSN）下的识别表现，来评估WIN的标准效度。MTB和SSN具有相同的均方根值和相似的频谱，但具有不同的幅度调制特性。正常听力的听众在MTB中的表现比在SSN中好2 dB，比听力损失的听众的表现大约好10 dB，听力损失的听众在MTB中的表现比在SSN中好约0.5 dB，其中56%的听众在MTB中表现更好，40%的听众在SSN中表现更好。正常听力听众的函数斜率（8 - 9%/dB）比听力损失听众的函数斜率（5 - 6%/dB）更陡。数据表明WIN具有良好的标准效度。
