Mandarin sentence recognition using natural-tone and flat-tone sentences was tested in 22 subjects with sensorineural hearing loss (SNHL) and 25 listeners with normal hearing (NH) in quiet, speech-shaped noise, and two-talker-babble conditions. While little effects of flat tones on sentence recognition were seen in the NH listeners when the signal-to-noise ratio (SNR) was ≥0 dB, the SNHL listeners showed decreases in flat-tone-sentence recognition in quiet and at +5-dB SNR. Such declined performance was correlated with their degrees of hearing loss. Lexical tone contributes greatly to sentence recognition in hearing-impaired listeners in both quiet and in noise listening conditions.
采用自然音和降调句子对 22 名感音神经性听力损失(SNHL)患者和 25 名正常听力(NH)受试者进行了测试,分别在安静、语音噪声和双说话者噪声环境下进行。当信噪比(SNR)≥0dB 时,NH 受试者对降调句子的识别几乎没有影响,但 SNHL 受试者在安静和+5dB SNR 时对降调句子的识别能力下降。这种表现下降与他们的听力损失程度相关。在安静和噪声聆听环境中,声调对听力障碍者的句子识别有很大的贡献。
