Measured noise levels of Dyson Airblade™ hand dryers in UBC Vancouver-campus washrooms Daltrop, Shira


There has been a recent study which discusses the sustainability of using paper towels as opposed to hand dryers in washrooms on the UBC Vancouver campus. Dyson Airblade™ hand dryers were found to be the most effective method of hand drying; however, they are known to be quite loud. In this study, noise levels from the Dyson Airblade™ hand dryers were measured in three different washrooms on the UBC Vancouver campus. The measured noise levels were compared with noise levels from several typical hair dryers. It was found that the total A-weighted sound levels were similar for both devices, with levels of approximately 84 dBA. Noise levels were also measured in the occupied hallway outside of one washroom while a Dyson Airblade™ hand dryer was in use and not in use; the dryer increased hallway noise levels by 5 dBA.
