Hearing Protection

What does "attenuation" mean?

It is the difference between the noise level outside the ear defender to the level inside the ear defender - in other words, the reduction in noise level. Ear defenders attenuate differently at different frequencies.

What does H,M,L stand for?

The letters stand for the level of attenuation at different frequencies :

H = high

M= medium

L= low frequencies

What does SNR mean?

SNR relates to a statistics based single number ratio indicating how ear defenders perform across the noise spectrum. Often, individual frequencies attenuation can be vastly different to that indicated by the SNR value. Both SNR and H, M, L are sometimes used incorrectly, to determine whether an ear defender is fit for purpose.

What is the legal limit for noise?

The Noise at Word Regulations 1989 permit a maximum exposure level of 85 decibels dB(A).

What are the various standards for the different types of ear protection?

EN352-1:1993

  • Hearing Protectors - Safety requirements and testing
  • Part 1. Ear-muffs
  • Relates to ear-muffs (headband mounted)

EN352-2:1993

  • Hearing Protectors - Safety requirements and testing
  • Part 2. Ear plugs
  • Relates to ear-plugs and also includes custom moulded ear-plus and banded devices

EN352-3:1997

  • Hearing Protectors - Safety requirements and testing
  • Part 3. Ear-muffs attached to an industrial safety helmet
  • Relates to ear-muffs fitted to an industrial safety helmet
