Abstract:
The finger pulse amplitude of 10 healthy men (aged 20 to 30 years) was measured during noise (70, 80 and 90 dBA) and combined exposure (local muscular work with 30% MVC and noise with 70, 80 or 90 dBA) and during a recovery phase of 60 min. The finger pulse amplitude was reduced only during noise exposure with 90 dBA and was increased during the combined exposures. A continuous decrease of the finger pulse amplitude was observed during the recovery phases. Differences between noise exposure and combined exposure do not exist. The findings were discussed as the risk of hypertension in workers exposed to noise.
