The computer method for the articulation loss of consonants as a criterion for 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 fol owing 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.
