- Adjustable headband - The alternative to ear-muffs which are attached to the helmet: suitable for helmets, face shields, respirators and other PPE. - Ventilated inner headband - Snap-ear cushions ensure quick and easy replacement - Elastic headband for better placement - Damping H=32dB, M=28dB, L=21dB, SNR=30dB
SNR (Single Number Rating (one number designation) indicates the number of decibels by which the noise level is reduced with the use of hearing protectors. The higher the SNR, the better you'll be protected.
For example, being exposed to a noise level of 110dB (when using a portable power tools) is an SNR protection of at least 30dB is required. 110dB - 30dB = 80dB. It is imperative to monitor the attenuation value with the SNR value stated on the packaging.
