室内语言辅音的清晰度损失与声源指向特性的关系

The Relationship Between the Articulation Loss of Consonants in a Room and the Directive Characteristic of Sound Source

介绍了室内音质评价量、辅音清晰度损失的计算方法;室内语言清晰度损失与声源指向特性的关系以及汉语语音的特性,听力随年龄增长的听阈下降的统计值和通过声源覆盖角计算指向性因数的方法。

The computer method for the articulation loss of consonants as a criterion the speech transmission in a room and the relationship between the articulation loss of consonants and the directive characteristic of sound source were presented in the paper. The following contacts were introduced including the characteristic of Chinese speech sounds, the statistical distribution of hearing thresholds descent as a function of age, the compte method of directive factor by the coverage angle of sound source.
