Abstract
Interviews among a selection of 37 of the 289 Swedish local Environmental
Health Authorities (EHA) were undertaken in order to assess the occurrence
of complaints on low frequency noise. The study also aimed to evaluate
whether the specific guidelines on low frequency noise, adopted in
1996, were used and how they performed when assessing low frequency
noise. The results showed that most complaints of low frequency noise
were due to noise from fan- and ventilation installations, amplified
music, compressors and laundryrooms. According to 46% of the EHA,
complaints due to low frequency noise had increased during the last
two years, while the same percentage reported no change. When assessing
low frequency noise, 62% of the EHA reported that the specific guidelines
on low frequency noise based on third octave band analysis performed
better or much better compared to the previous A-weighted guideline,
and only one EHA thought it performed worse.
