We are exposed to noise every day, some of which has the potential to damage our hearing. Hearing loss develops gradually and painlessly which is why we tend not to notice it until it is too late.
It is essential to protect our ears from harmful levels of noise, but how do we know what is a “harmful level”? The maximum periods of time a person should be exposed to harmful noise per day without hearing protection can be surprising.

What level of noise protection is required?
Each hearing protector is tested to determine its individual level of noise reduction when fitted correctly. Each protector has an SNR which is an abbreviation for Single Number Rating. The higher the SNR value of a hearing protection product, the higher the noise insulation provided.
To find out the protection figure required, the noise levels of the workplace must first be established. This is the calculated figure for the amount of potential protection the protector can provide when fitted correctly. For this, the noise levels need to be measured to determine the daily exposure levels, as well as any maximum or peak noises that might have an impact. A noise map is then established and then the required protection can be determined using the SNR method.
The objective when choosing suitable hearing protection is to achieve an effective residual noise level of between 70 dB and 75 dB for the wearer. If the protection provided is too high (over-protection) this can result in an inability to communicate and potentially not hearing any warning alarms.
