An Investigation and Assessment of Annoyance of Low Frequency Noise in Dwellings

摘要

Appliances installed in residential buildings such as transformers, air-conditioners and freezers are often sources of low frequency noise. Although sound levels inside dwellings from these sources are low, the dwellers evaluate the noise as annoying. This paper presents the results of an investigation of annoying low frequency noise in dwellings. Measurement results are shown and methods of annoyance assessment are discussed.
