| Research Abstract |
For the efficient and safe working, it is important how one can communicate by speech. In this report, we describe about 4 topics.
1st: about Infrasound.
In the noisy places, there also exists infrasound. We have reported elsewhere that inner ear plays an important role an the recepter of infrasound. Combined stimmulation of sound and infrasound may effect hearing organ or hole body condition. This effect was easily influenced by individual susceptibility.
2nd: about Noise Induced Hearing Loss.
We found possibility of developing more hearing loss when one fried to pick up information from noisy environment.
3rd: about Occupational Voice Disorders.
We investigated voice disorders for the employee who had communicate under noisy conditions, We measured noise intensity, analysed the voice, and examined the vocal cord of those employee.
Finally: about Hearing Aid.
We have been trying to improve hearing aid to get comfortable communication by reducing unpleasant background noise.
