References: <3qeoqu$5lp@eagle.novo.dk> Date: Fri, 2 Jun 1995 19:36:14 GMT X-News-Software: Ameol Lines: 18 I came across this phenomenon several times in my previous job as an technical officer with an environmental health authority in London. We received several complaints from members of the public in different areas who were plagued by what they all described as a constant low pitched hum although I, nor my colleagues ever heard the sound. Although we eliminated all possible sources nearby (such as mains transformers, pumps and other building services) we could never find the cause. Some complainants were so bothered that they had been put on tranquillisers. We also couldn't detect any stationery low frequency tones using real time frequency analysis (down to 5 Hz). We contacted the Low Frequency Noise Sufferers Association in the Britain and found that the majority of their members, experiencing similar problems, only heard the sound in one ear. Sound Research Laboratories in the UK undertook a research program into low frequency tinnitus but I never got around to seeing their conclusions. Maybe this would throw some light on the mystery.
