在一教室听音位置，通过声学仿真获取中低频混响时间频率特性平直、混响时间不同的两个房间脉冲响应，采用可听化方法在低频噪声和白噪声条件下对两组不同年龄的儿童进行主观音节识别评价，并与成年人的结果进行对比．结果表明: 低频干扰噪声下儿童的音节识别得分比白噪声下的低; 不管干扰噪声是低频噪声还是白噪声，相同信噪比和混响时间下，儿童的汉语音节识别得分比成年人的低; 儿童年龄越小，主观音节识别得分越低．

Two room impulse responses with flat reverberation frequency characteristics and different reverberation time in low and medium frequency domains were obtained in a listening position of a classroom model through acoustical simulation.Then,the Chinese syllable recognition performances of two groups of children in differentages were evaluated under white noise and low- frequency noise conditions via an auralization method,and the re-sults were finally compared with those of adults.It is found that (1) the Chinese syllable recognition scores of chil-dren in low- frequency noise are lower than those in white noise; (2) no matter what the frequency condition of noise is,the Chinese syllable recognition scores of children are lower than those of adults at the same signal- to- noise ratio and reverberation time; and (3) the Chinese syllable recognition scores are positively related to children’ s age.
