N/A Objective : This study investigated changes of voice and hearing in premenopausal and postmenopausal woman Methods : We studied forty postmenopausal and forty premenopausal women. Each women was asked to describe their subjective vocal symptoms and phonate a vowel /a/ sound for 3 seconds. The phonated sound in each case was recorded and analysed by the computerized speech lab (LSL 4300B, KAY Elemetrics Corp. USA). We also conducted audiometric pure-tone threshold testing on the same group. Statistical analysis of voice and hearing parameters was done by paired T test Results : Jitter in menopausal group was significantly increased compared with premenopausal group, but other voice parameters showed no significant differences. There were no significant changes of vocal parameters between menopausal patients with or without vocal symptoms. And there were no significant changes of hearing parameters, either Conclusion : The change of voice parameters was objectively identified in menopausal women, and so therapist of menopausal symptoms must take the voice changes into consideration.

The concern of traffic-induced vibrations(and noise) becomes more important because of environmental regulations and detrimental effects on structures, etc. However, studies about this subjects are not enough around us to protect people and facilities against it. Accordingly, field surveies over Pusan area are performed to investigate actual conditions of traffic-induced vibrations and noise level. Survey results are analysed to draw characteristics of them and to make a prediction method of vibrations. Conclusions obtained from the study are following : 1. Railroad-induced vibration and noise exceed the environmental criteria, the proper counter plan may be needed. 2. Vibrations induced by total cars traffic are below the criteria, but noise in well over and it may cause negative effects on people near roads. 3. The regression equations deriven in this sutdy may be used to predict vibrations caused by single car and railroad traffic, except by total cars traffic.
