Exposure of the crew of a fishing trawler-factory ship to noise.

The noise level was measured in the workplaces and in living quarters on a fishing trawler-factory ship, type B-418, in the fishing grounds. It was found, that an average noise level in the engine room was from 97 to 104 dB A. The noise level registered in the living and resting areas on board did not exceed the admissible values. In the fish processing plant the noise levels ranged from 84 to 97 dB A. The equivalent noise level for the engine room crew exceeded 90 dB A by 7-15 dB A; in the fish processing plant and on the bridge it remained within the norm limits.
