Noise and Health
Low frequency noise, considered as the frequency range from about 10Hz to 200Hz, causes extreme distress to a number of people who are sensitive to its effects. The sensitivity may be a result of heightened sensory response, within the whole or part of the auditory range, or may be acquired. Onset of low frequency noise annoyance tends to occur in middle age. The noise levels are often low, in the region of a subject's hearing threshold, where there are large differences between individuals. The problem arises both in homes and in offices, or similar, premises. Whilst noise sources causing annoyance in the home may be unknown, in offices they are often fans or pumps in the building services. Similar plant, in those apartment blocks which have central services, may be the source of the noise in these premises, but a core of low frequency noise problems remain, of unknown origin, which continue to cause considerable annoyance. Low frequency noise problems also occur in industry, but generally at levels well above threshold, presenting a different noise problem to those in homes and offices.
The Waubra Foundation
The Waubra Foundation is a national Australian organisation formed in 2010 to facilitate properly conducted, independent multidisciplinary research into the new health problems identified by residents living near wind turbines and other industrial sites which may have common cause.
There is a long history of acoustic and clinical research into the adverse health effects of noise on health (and sleep), including audible noise, infrasound, low frequency noise and vibration.
