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.
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.
