Hand Dryers Noise Level Explained
Customers and Facilities managers are becoming increasingly concerned about the noise level of hand dryers. Loud hand dryers can make washrooms and areas in close proximity to office space disturbing and sometimes distractive. Although it is very hard to indicate the noise level of hand dryer over the phone or YouTube Video, we thought at justwashroom to put togther a table indicating the level of noise in dB measure so customer can compare the noises or different machineries:
- Near total silence - 0 dB
- A whisper - 15 dB
- Normal conversation - 60 db
- Hand dryer Vortex OZ1650 67db
- Hand dryer Vortex VX2100 68db
- Hand dryer Vortex VX2006 74db
- Hand dryer Vortex XL228 80db
- The Dyson airblade 85db
- A lawnmower - 90 dB
- A car horn - 110 dB
- A rock concert or a jet engine - 120 dB
- A gunshot or firecracker - 140 dB
The decibel (dB) scale is logarithmic, which means an increase of noise level by 10db that is twice as loud and increase of 20db about four times as loud.
So the question arise what dB of sound is safe? Generally speaking highest anyone should go is 85 dB, see what Work Safe Australia says about this
"50 decibels if your work requires high concentration or effortless conversation
70 decibels if your work is routine, fast-paced and demands attentiveness or if it is important to carry on conversations"
