Ear Muffs

Sir Safety industrial ear muffs protect hearing in high-noise environments — workshops, generators, compressor rooms, mining, construction. EN 352-1 (over-head) and EN 352-3 (helmet-mounted) certified, with AS/NZS 1270 referenced ratings from SNR 26 dB through to SNR 34 dB. Stark and Verishield ranges supplied across Australia and New Zealand.

Matching Attenuation to Noise Exposure

Australian WHS requires hearing protection wherever sustained exposure exceeds 85 dB(A) over 8 hours. Workshop and light construction typically use SNR 26–28 dB. Heavy machinery, mining, and forestry use SNR 30+ dB. Over-protection causes communication problems and worker non-compliance — under-protection causes long-term hearing loss. ProfTek can supply Sir Safety attenuation datasheets to match the SNR to your measured workplace noise level.
