If you need quiet hand dryers, take a look at this section. For hand dryers there is no approved testing method that manufacturers must adhere to, therefore the stated decibel level can be particularly unreliable information to base a specification on. Please get in touch if noise is an important issue and we can talk you through the nuances. Noise measured at 1 or 2 metres is not necessary a good indication of how far the noise will travel as this may be more dictated by vibration and pitch. If you are specifying hand dryers please do not specify a product on the basis of dB(A) as it frequently leads to poor choices. The hand dryers in this section are Quiet but effective. Many are independently Quiet Mark approved.
