Dangerous noise levels - volume 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?
Clearly, the higher the noise 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 this critical point 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 for 8 hours, but if you choose to have more, then you use up the lumps faster and then anything else becomes excessive.
