It’s no secret that hand dryers installed in public bathrooms can seem rather loud, but we were blown away by a young scientist’s findings when she put the volume levels of 44 automated machines to the test in restrooms across Alberta, Canada.

Turns out some of those volumes can do a number on kids’ ears — which are more susceptible to noise-induced hearing problems — by reaching sound levels well beyond the danger zone of 85 decibels. Several of the various brands measured above 100 decibels when in actual use for hand-drying, and one was even greater than 120.

The study, by then-9-year-old Nora Keegan, has captured international attention, with coverage by the New York Times, CNN, Canada’s CBC, and other media outlets. Now 13, Keegan is likely one of the youngest researchers to have her work published in the journal Paediatrics & Child Health. …
