(another summary in Swedish)

The goal with this investigation (Carl Hogstedt, Greta Smedje, Robert Wålinder, Akademiska Hospital, Uppsala, Sweden) was to examine if the work as a teacher and the noise exposure in schools leads to a higher risk for hearing impairment and tinnitus, sound sensitivity and vocal problems.
Audiometric measurements show an increased occurrence of hearing impairment among school and preschool staff.
25% of the respondents said they have a hearing impairment, 21% said they have problems with tinnitus, 29% said they have voice strain and 18% hoarseness.
Noise exposure during a working day varied from 65 dB to 78 dB LAeq.
