Noise levels versus exposure time
|dB(A)||Time to reach limits|
|90||2 hrs 30 mins|
|92||1hr 30 mins|
|93||1hr 15 mins|
Ever wondered how long you can be exposed to a noise before you reach the point at which the sound level has a significant risk to your hearing?
The safe limit for hearing is 85 decibels over eight hours but the higher the noise levels go then the shorter the time you can be exposure to it before your ears can take no more.
All the figures in this table are the times you would need to be exposed to the noise for before you reach the same exposure as 85 dB over eight hours, and into the area where hearing damage becomes a real risk.
As the noise levels go up these times become very short indeed.
The best way to think about it is that you can have a set number of lumps of noise before it is too much and starts to damage your hearing. The limit in the regs is 85 of these lumps over 8 hours, but if you choose to have more, then you use up the lumps faster and then anything else becomes excessive.
