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.
Perhaps the first sign that this book would be a let down were the typos throughout the pages (such as "hunbands" for husbands p 211, "sores" for scores p 104). The carelessness of the authors was reflected in the poor quality of the content and its presentation. This book lacked a coherent voice, and others have noted the contradictory statements found throughout its pages.
Thus, we propose that your government needs to withdraw proposed changes to age ranges, ratios and group sizes. Instead we recommend that the government develop a well-considered road map that begins with a clear vision, goals/objectives, targets and timetables, with regulatory changes as one part of this plan. This would have a better chance for successful policy change. We also call on Ontario to play a positive leadership role with the new federal Liberal government and other provinces/territories in developing the high quality universal integrated ECEC system that so many have been seeking for so long.
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.
