Ear Defenders

Ear defenders reduce the noise exposure level, providing hearing protection where the sound level cannot be reduced below 80dB by taking noise level exposure actions. Here at RS we offer a great range of Ear Defenders with a Single Number Rating between 23dB -37dB. The SNR value can be used to compare the level of noise attenuation offered by different Ear Defenders. To determine acoustic pressure on your ears, you subtract the SNR value from the average noise level measured, for example: the noise level measures an average of 99 dB, you are wearing ear protection with an SNR of 19 and the acoustic pressure on your ears is on average 99 – 19 = 80 dB. The higher the SNR, the higher the level of noise attenuation provided by the hearing protection. With a choice of ear defenders with either a headband or for attaching to a safety helmet you are sure to find the best match for you.
