The aim of this project was to survey room acoustics for hearing-impaired persons. The room acoustics of reverberation time, noise level and rapid speech transmission index (RASTI) were measured for classrooms, training rooms, playing rooms and auditory test rooms at the four schools for the deaf in Fukuoka prefecture. A few of the classrooms and auditory test room were found to have long reverberation times. The results showed that hearing-impaired students in the rooms might not hear the teacher's speech well. The room acoustics of six public halls in Fukuoka city were measured in the same way. The RASTI value of each public hall was good for normal-hearing persons. However, the RASTI values indicated that it was difficult for the aged persons with mild hearing loss to listen successfully.A new method fir hearing aid fitting was proposed using speech materials with different reverberation times in a soundproof booth The method can evaluate speech recognition scores under a real reverberant environment for hearing-aid wearers. In addition, a prediction method of the usefulness for an FM hearing-aid wearer under reverberation was developed, and acoustic characteristics of a digital hearing aid with an adaptive directional microphone system using a moving sound source were studied.

该项目的目的是调查听障人士的室内声学。对福冈县4所聋人学校的教室、训练室、游戏室和听力测试室的混响时间、噪声级和快速言语传递指数（RASTI）进行了室内声学测量。少数教室和听力测试室被发现有很长的混响时间。结果表明，教室里的听障学生可能听不清老师的讲话。用同样的方法对福冈市的六个公共霍尔斯的室内声学进行了测量。各公共大厅的RASTI值对于听力正常者来说是好的。本文提出了一种在隔音室中使用不同混响时间的语音材料进行助听器验配的新方法，该方法可以评估助听器佩戴者在真实的混响环境下的语音识别成绩。此外，一个有用的FM助听器佩戴者混响的预测方法的开发，并与自适应定向麦克风系统使用移动声源的数字助听器的声学特性进行了研究。
