[Evaluation of the noise produced by mechanical saws used in forestry].
The noise level of 25-motor-saws used for felling and processing wood has been measured. There were found that the saws are the source of an intermittent noise, and the break periods of various duration occur irregularly. The sound pressure level ranges from 100 dBA to III dBA (N97-M108) and the daily noise exposure of a sawyer amounts to 77 minutes. Evaluating the noise produced by motor-saws by means of damage risk criteria for intermittent exposure, it was stated that the noise level exceeds slightly the allowable values. The statistical analysis showed correlations between noise level and type of the saw, speed of motor turns and degree of saw wear.
