The DANR THPC Headset represents our top-of-the-line product that combines triple hearing protection and communications, for use in extreme noise environments up to and exceeding 140 dB(A). The cirmcumaural headset with detachable battery and integrated digital processor is our most capable broadband noise protection system, providing three layers of hearing protection .The Aegisound DANR THPC Headset provides two passive layers of hearing protection and adds a third layer via DANR custom communication earplugs. Two-way communications capabilities are included through the addition of a superior digital noise canceling microphone with a muzzle and attachment to a user’s radio or intercom system. This system enables two-way communications in the highest ambient noise fields; it meets the requirements for industrial use and of the US Navy and Joint Strike Fighter (F-35) prime contractor, Lockheed Martin.

Noise Reduction Rating: 32 dB. The DANR systems provides an equivalent NRR of 37 dB via total passive and active attenuation per ANSI S12.6 and ANSI S12.42 test methodologies. Active noise reduction measured at 140 dB(A) in accordance with ANSI S12.42 (MIRE) was combined with the ANSI S12.6 passive attenuation data.
