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.
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.
