✦ Synopsis


Industrial noise may lead to noise annoyance in residential areas, in particular when such areas are located close to industrial plants. Specific reduction of noise requires detailed knowledge of the complaints from the residential neighbourhood and their relation to the noise source.

The membership companies of the German Federation of Chemical Industry have recorded 230 noise complaints from 1977 to 1979. In relation to these Complaints, parameters, e.g. nature of noise source, noise character, time of noise occurrence, meteorological conditions, were investigated and statistically evaluated.

Fifty complaints out of the 230 were quantitatively evaluated with respect to the background and noise level at the location of complaint. It resulted, that only 16 % of the complaints are based on broad band noise, whereas 84 % on impulse noise and single tones. Broad band noise causes complaints beginning at 65 dB(A), impulse noise at 56 dB(A) and single tones at 50 dB(A).

* The confidence range for the immission sound level during complaints was calculated for a confidence level of 1 -a = 0.95 at two-sided limitation (DIN 53 804, Part 1). 1
