• Syllable recognition

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 different ages were evaluated under white noise and low-frequency noise conditions via an auralization method, and the results were finally compared with those of adults. It is found that (1) the Chinese syllable recognition scores of children 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.
