Hand Dryers Noise Levels
It is hard for ordinary person to work out the noise level in db, which is the measure of noise level.
High airflow hand dryers are found in many public restrooms and office blocks today.
These dryers offer quick and clean hand drying, and are seenas being an environment-friendly alternative to paper towels. However, many new hand dryers are loud, exposing individuals using the facilities. While hand dryers do reduce paper trash, they pose as a different sort of hazard to our environment and population.
Many people don't knowthe measure of noise intensity (in dB) of the noise produced by the air dryers in campus restrooms.
The decibel ( dB) is used to measure sound level, but it is also widely used in electronics, signals and communication. The dB is a logarithmicway of describing noise. We relate dB to the phones and the machinaries (related to loudness), and now a days it is a measure of hand dryer noise.
So in order to make it easier for any facility manager to decide or builder or any person intending to purchase a hand dryer, we have produced a simple chart of noise levels associated with different environment compared with differnt models of hand dryers.
