Abstract
In a group of 123 persons recordings of noise exposures and annoyance were carried out twice during a working day. The recordings represented four different types of working environments; control rooms (n = 56), laboratories (n = 6), offices in industries (n = 30) and offices in administrations (n = 31). The noise exposure levels varied between 40 and 70 dB(A). The mean different time of noise exposure was 3 hours with a shortest time of one hour and a longest time of five and a half hours. The results were not unequivocal but indicated a lowered annoyance at the second occasion for all groups but the control room group, representing the most pronounced low frequency environment.
