| Abstract |
This study was designed to determine whether a combination of noise and vibration produced more pronounced changes in temporary shifts of finger skin temperature and temporary threshold shift (TTS) of hearing than those resulting from exposure to either stress alone. Nineteen healthy subjects were exposed to 6 different combinations of vibration, noise and handle holding by using a chain saw for a pre-determed time. The mean value of normalised finger skin temperature decreased much more when the subjects operated a chain saw at high speed than when they operated the chain saw with the noise isolated by double hearing protection. Noise may play a part in inducing the constriction of peripheral vessels seen with local exposure to vibration, and hand-arm vibration may produce an additive effect on the noise-induced TTS. |
