Spontaneous otoacoustic emissions (SOAE)s are sounds that are emitted from the ear without external stimulation and are measurable with sensitive microphones in the external ear canal. At least one SOAE can be detected in approx. 35-50% of the population. The sounds are frequency-stable between 500 Hz and 4500 Hz to have unstable volumes between -30 dB SPL and +10 dB SPL. The majority of the people are unaware of their SOAEs; portions of 1-9% however perceive a SOAE as an annoying tinnitus.
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.

In 2009, Stephen Beeby of The University of Southampton led research into utilizing otoacoustic emissions for biometric identification. Devices equipped with a microphone could detect these subsonic emissions and potentially identify an individual, thereby providing access to the device, without the need of a traditional password. It is speculated, however, that colds, medication, trimming one's ear hair, or recording and playing back a signal to the microphone could subvert the identification process.
The relationships between otoacoustic emissions and tinnitus have been explored. Several studies suggest that in about 6% to 12% of normal-hearing persons with tinnitus and SOAEs, the SOAEs are at least partly responsible for the tinnitus. Studies have found that some subjects with tinnitus display oscillating or ringing EOAEs, and in these cases, it is hypothesized that the oscillating EOAEs and tinnitus are related to a common underlying pathology rather than the emissions being the source of the tinnitus.
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.

We recognize that there are good reasons to make changes in early childhood education and care (ECEC) in Ontario. But we believe that these must be based on the best available evidence about what is of most benefit to children and families; we argue that these proposed changes are not. Additionally, we suggest that changes in ECEC in Ontario will continue to have negative effects if they continue to be “piecemeal”.
Shawna Kay – Mom of two children in care. My youngest isn’t quite 1 yr old yet. How much more difficult do you need to make it for us? I barely make enough to cover daycare as it is, and that’s WITH subsidy! The ripple effect here is going to negatively impact so many. Please think of how much these changes are HURTING people who are just scraping by as it is!!!!
