SNR (Simplified Noise Reduction):
Single average value of attenuation
The performance of the hearing protector (it's attenuation level) must be adapted to the risk assessment of the workplace. It should bring the noise level that is not harmful to life, while avoiding over-protection which would cut the operator from his environment (warnings, communication, etc).
Requirements Directive 2003/10/EC
Minimum requirements for the protection of workers against the risks related to noise exposure
8 hours exposure time at or above 85dB - Obligatory hearing protection
8 hours exposure time as or above 80dB - Hearing protection available to the worker
8 hours exposure time between 75dB and 80dB - Hearing protection recommended
How to protect yourself?
4 steps to choose the appropriate hearing protection
1. Identify the nature of the noise: stable, fluctuating, intermittent or pulse.
2. Measure the noise at the working station: intensity (dB) and volume (Hz).
3. Determine the exposure time.
4. Calculate the required reduction to return to a background level acceptable (see Directive 2003/10/EC).
