An otoacoustic emission (OAE) is a sound which is generated from within the inner ear. Having been predicted by Thomas Gold in 1948, its existence was first demonstrated experimentally by David Kemp in 1978 and otoacoustic emissions have since been shown to arise through a number of different cellular and mechanical causes within the inner ear. Studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health.
In conjunction with audiometric testing, OAE testing can be completed to determine changes in the responses. Studies have found that exposure to noise can cause a decline in OAE responses. In a study, industrial workers who were exposed to 84.5 dBA of noise were compared to workers who were exposed to 53.2 dBA of noise by considering hearing thresholds and OAEs before and after 5 days of work. This study revealed that hearing thresholds and OAE results were significantly lower among the workers who were exposed to higher levels of noise.
- A suggestion that it is not necessary to consume large amounts of water before and during pregnancy (p35). Apparently, the best way to hydrate your body is to 'consume plenty of healthy fats, because fats provide the most energy on the cellular level - much more than carbohydrates and proteins, and the by product of this energy is water'. I don't know enough about this matter to comment further at this stage, but I find it strange that drinking water would be discouraged.
