ELECTRONIC SOUND AMPLIFICATION Impact’s patented sound amplification enhances the wearer’s awareness of their environment by amplifying ambient sounds, allowing them to hear important communication [co-workers, alarms/warning signals]. DIRECTIONALLY PLACED STEREO MICROPHONES Provide more natural hearing. IDEAL FOR HEARING IMPAIRED WORKERS LIMITS SOUND AMPLIFICATION Sound amplification volume does not exceed 82 dB – response technology revert to passive hearing protector when noise reaches 82 Db. SNAP-IN EAR CUSHIONS Make replacement quick and easy. ATTACHES TO POPULAR HELMETS HELMET ADAPTERS INCLUDED (3711, 3712, 3713, 3714, 3718, 3721)


The Impact earmuff enhances user awareness of their environment through advanced sound amplification technology. Impact allows wearers to hear important communication – other co-workers, alarms and warning signals – at a safely amplified level. Positioned microphones provide more natural, directional hearing. Through an advanced response technology, Impact reverts to passive earmuff mode when noise reaches 82 dB or above. Impact is ideal for hearing impaired workers and can help prevent isolation on the job.
