The PTL HT listen-only hard hat model headset offers safe attenuation with the push of a button. This comfortable and durable communications headset allows for long-term use under exacting conditions.
The practice of "lifting off" an earmuff to hear can compromise attenuation and protection for wearers. 3M Peltor`s PTL earmuff helps resolve this problem by allowing "outside the muff" sounds to be heard clearly when needed. The PTL HT Series listen only hard hat mount model also features: - Earcup button for listening mode - Listen-through capabilitiy with the pass-through sound limited to 87 dB - Auto-switches to full protection after 30 seconds or when button is pressed again - Earcups with liquid and foam-filled comfort cushions for long wear and optimum seal - Possible industries include: heavy equipment operators, airports, manufacturing, construction, agricultural, racing, oil rigs, petroleum refineries - NRR 25dB* *The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. 3M is Leading the Advancement of Hearing Conservation™
