Recordings of nonsense syllables (VCV construction) were presented to groups of children aged 5, 7, 9, 11, and 13 years and young adults under monaural (reverberation time = 0.6s) and binaural (reverberation times = 0, 0.4, and 0.6 s) conditions of reverberation. Phoneme identification performance was affected by age, reverberation, and mode of presentation (monaural versus binaural). The major findings were (1) phoneme identification scores in reverberant conditions improved with increasing age and decreased with increased reverberation time; (2) children's performance in reverberant conditions did not reach asymptote until age 13; (3) binaural performance was consistently better than monaural performance for all age groups, with 5-year-olds showing the largest binaural advantage.
向5岁、7岁、9岁、11岁、13岁的儿童组以及年轻成年人呈现无意义音节(VCV结构)的录音,呈现条件为单耳(混响时间=0.6秒)和双耳(混响时间=0、0.4和0.6秒)混响。音素识别表现受年龄、混响和呈现方式(单耳与双耳)影响。主要发现为:(1)混响条件下的音素识别分数随年龄增长而提高,随混响时间增加而降低;(2)儿童在混响条件下的表现直到13岁才达到渐近线;(3)所有年龄组的双耳表现始终优于单耳表现,5岁儿童的双耳优势最大。
