Abstract
The presence of subjective noise annoyance was investigated among
workers in a machine factory and a textile mill by using a questionnaire.
The relation between annoyance due to noise and annoyance caused
by other factors in the work environment was also investigated. The
results show that annoyance due to noise exposure was common in both
factories. Apart from the relation to the noise level, other acoustical
characteristics, such as frequency spectrum and intensity, as well
as differences between background and peak levels seem to determine
the extent of annoyance. In the machine factory, the general satisfaction
at work was significantly less among workers who had reported annoyance
from noise, insufficient natural and artificial daylight and dust.
In the textile mill noise and dust as well as monotonous work and
fast working pace were of importance for the general satisfaction
at work. Headache and tiredness were more common in the textile mill.
The techniques used in the study could be applied to obtain further
information on other industrial noise exposure criteria than hearing
damage to serve as a basis for standards for annoyance.
