Abstract
A laboratory experiment was carried out concerning: (a) the effects of industrial noise on man and (b) the influences of some personal characteristics on those effects. Twenty eight volunteers performed the same experiment twice. On the second occasion, they were exposed to high-level industrial noise of 94 dB(A), produced by a variety of machines. Steady state and impact noise were included, with the reproduction arranged to produce both near-field and distant-field noise. Results showed that in the experimental situation of exposure to noise, there were some changes in the subjects' perseverance in puzzle solving and in the performance of spontaneous rhythm tasks. On the other hand, results showed that in the experimental situation personal characteristics such as anxiety and non-specific psychopathological symptoms did not have a significant influence on the changes of performance of tasks. Nevertheless, some interesting trends were found, requiring further research.
