Take steps to improve concentration and boost pupil outcomes
As any teacher knows, any disruption to a lesson can affect the ability of pupils to concentrate on their work. Poor classroom engagement can result in lesson overruns and add pressure to teachers in delivering the curriculum effectively. Pupils leaving the class to use the bathroom during lessons is an unavoidable issue, but the noise from hand dryers leaking into the classroom and disturbing concentration is not. Choosing quieter hand dryers means less disturbance to lessons in areas close to the bathrooms.
How Noisy are Hand Dryers
Conventional hand dryers work by evaporation. A fan inside the dryer blows air over a heating element and through a wide nozzle onto the user’s hands. The size of the nozzle, coupled with the exposed fan and motor assembly creates a significant amount of noise from machinery and turbulence. As the appliance ages, the noise can get worse due to components wearing out and damage to fan blades.
A traditional hand dryer is as noisy as standing next to a busy road or a train in a station: 85dB.
This loud noise not only leaks into the surrounding area but can also be daunting for some children with auditory sensitivity and cause them to avoid using the dryers or omit hand washing.
