peaceful washrooms are back. Do you find the noise produced by electric hand dryers to be jarring or even painful? You’re not alone. All electric hand dryers make noise, but some are worse than others, “causing discomfort to all, and unnecessary stress to those with hypersensitivity to noise, hearing problems or conditions such as dementia and autism.” Fortunately, a quieter alternative may be around the corner. Quiet Mark announces the launch of its review of hand dryers, stating that it:
[T]ested a broad range of hand dryers and only the quietest, high-performance machines achieved a Quiet Mark award. This universal symbol makes it easier for those in charge of restaurants, bars, leisure centres, shops, libraries, hospitals and public conveniences to consider sound levels when assessing hand dryers for their venues.
Quiet Mark’s testing uses real-life testing environments for accurate result, because “the sound levels of hand dryers in real-life situations have often been underestimated.” Among other things, Quiet Mark notes that hand dryers are:
[C]ommonly tested in ultra-absorbent acoustic laboratories, rather than in highly reverberant washrooms and toilets, where their loud motor noise can be uncomfortably amplified. They may also be tested without human hands in the airflow, which can add up to 10dB in some cases. The combination of these factors means that the machine can be twice as loud as some test results might show.
