How much noise to hand dryers make?
The design of a conventional hand dryer makes use of a combination of slow-moving air and a heating system. The air is drawn in from the surrounding area, passed through a fan system, warmed, and directed onto the user’s hands through a wide nozzle. This design, which has been in use for many years can be very noisy and create a lot of disturbance in the surrounding area.
Conventional evaporative hand dryers emit around 85Db of noise – the equivalent of a passing train. This level of noise can pass easily through walls and bathroom doors and create a great deal of disturbance in the surrounding area. While careful placement of Workplace Hand Dryers in bathrooms can impact noise levels, it cannot eliminate it totally.
Modern jet hand dryers can reduce noise levels considerably. The Mitsubishi Electric Wave u02 emits just 57Db of sound – the equivalent of a normal conversation, which creates much less noise pollution in any environment.
