Martula S2 Tradie Earmuff Class 5 29.2dB is superb hearing protection for loud environments. Meeting the AS/NZS 1270:2002 safety standard and rated Class 5, this premium earmuff reduces sound by 29.2dB for at least 80% of users based on the Sound Level Conversion (SLC80) method of testing. It is suitable for use in environments of up to 110dB as it reduces the continuous sound level to below 85dB, the acceptable standard for long-term exposure in loud environments as per the Workplace Health and Safety Regulation 2017.
 
It is important that businesses perform a sound audit or workplace noise assessment for each of their working environments prior to choosing hearing protection, and seek professional advice if the continuous sound level exceeds 110dB or the peak sound level rises above 140dB.
 
This tradie earmuff is made from cushioned plastic, with high quality oval-shaped foam cushions for a comfortable but secure seal, extendable arms for proper fit and two-point suspension for even pressure. This makes the headphones easy to wear for extended periods of time and greatly reduces external noise.
