Abstract
|
|
|
Accumulated noise exposure doses of engine test cell workers in air bases were measured with noise dosimeter. Mean accumulated noise exposure doses in F-4 engine test cell workers were 1.11±0.88% in indoor worker (n=2) and 1982±271% in outdoor worker (n=7) respectively. The difference of accumulated doses between indoor worker
and outdoor worker was statistically significant(p<0.01). When outdoor workers were classified into two group, engine checker and assistant, however, there was no significant difference. Accumulated noise exposure dose in F-16 engine test cell worker was 1851% (n=1), that of T-37 engine test cell worker was 96.6% (n=1). compared with
doses in F-4 workers, that of F-16 worker was not significantly different, but that of T-37 worker had significant difference (p<0.01). Hearing protectors of engine test cell workers were earplug, earmuff, and communication headset and it was recommended that they check the range of hearing protection of their protective devices and test only one engine per day.
