Noise exposure of farmers / 日本農村医学会雑誌

ABSTRACT

Noise exposure levels of 40 cases of farmers were measured by use of the equivalent sound level meters (Rion EQ-04).<BR>Legs during all over the day ranged from 74.3 dB-A to 89.3 dB-A. It can be seen that noise exposure levels during all over the day were mostly determined by amounts of the sound energy exposed by agricultural works.<BR>Most of farmers were exposed high level of noise in their home, and even in rest times.<BR>Legs during the agricultural work ranged from 70.4 to 100.6 dB-A, being attributed by agricultural machinary noise.<BR>Legs measured in the present study were compared with the criterion for noise of the Environmental Protection Agency, U. S. and discussed from the viewpoint of hygiene.
