抄録

This study was carried out with the purpose of grasping the influence of change of sound quality on the clarity of the Japanese monosyllabic for the sensorineural hearing loss person. Using the 67-S word table, heard the sound by the difference of the sound level of the consonant part and the vowel part, the sound subjected to the multi band compressor and the sound caused by the difference between speaker for hearing loss person and speaker for home-use. As a result, the smaller the sound pressure level difference between the consonant part and the following vowel part is, the more the clarity increases, the possibility that the word tone occurs due to the change in the characteristics of the following vowel, and the less the energy for each frequency of the following vowel is, the more the clarity is improved It showed the possibility.
