Frequently Asked Questions
OSHA requires hearing protection when workers are exposed to noise at or above 85 dB over an 8-hour shift. Chainsaws, chippers, nail guns, power saws, and heavy equipment all exceed that by a wide margin. Hearing loss from occupational noise is permanent and irreversible, and as an employer, failure to provide compliant PPE exposes your business to fines and liability. The A2 carries an NRR of 27 dB, which brings those environments down to safe, compliant levels.
NRR stands for Noise Reduction Rating. Think of it as a volume knob for harmful noise. A chainsaw or nail gun runs at around 100–110 dB, loud enough to cause permanent hearing damage in under an hour. NRR 27 turns that down to roughly 85 dB, which is where OSHA draws the safe line and strongly recommends hearing protection. Your workers can still hear what’s going on around them, but the damage just can’t get through.
Most cap-mounted earmuffs at this size are rated NRR 22. That 5-point gap might sound small, but decibels aren’t linear, and NRR 27 blocks roughly twice the damaging sound energy of NRR 22. The A2 gives you that higher protection in the same slim profile.
No. This matters especially if you’re ever inspected or face a workers’ comp claim. Consumer earbuds carry no certified NRR rating and are not recognized as PPE under OSHA standards. In a compliance review, they offer you zero legal protection and your workers zero verified physical protection. The A2 has a certified NRR 27 dB rating, ideal for most jobsites.
Electronic earmuffs have their place and can be beneficial for teams, but they come with tradeoffs. They require battery management, and they’re bulkier on the head.
Foam plugs work on paper but fail in practice. Workers lose them, forget them in the truck, or skip reinserting them because their hands are dirty. The A2 lives on the helmet, so it’s always within reach. Workers flip it into position with one motion when noise starts, and flip it back when it stops.
The A2 is engineered specifically for the Defender Safety H2 helmet. That dedicated fit is what makes the tool-free installation possible and keeps the protectors secure throughout the workday.
The A2 is a tool-free installation and clicks directly onto the Defender Safety H2 safety helmet. If you’re managing a job site, no training overhead is required. Workers can easily move it out of the way when needed and back into position in one easy swiping motion.
Yes. The A2 contains no metal components, making it safe for use in electrical environments where conductive PPE introduces risk. If any of your workers are on utility, panel, or electrical jobs while helmeted, the A2 doesn’t create a new hazard.
