Dual protection is often a requirement in many critical working areas where exposures may exceed 95 decibels (dBA), Sensear has integrated our SENS communication capabilities into an intrinsically safe dual hearing protection headset (ISDP) so users can effectively communicate without removing their hearing protection in these extremely high noise conditions.

Based on the existing SM1P IS headset, and incorporating the dual protection feature from our non-IS dual protection headset; the IS-SDP fills the marketplace need for a high performance intrinsically safe headset for extreme noise environments 

Users of the IS-SDP will benefit from these communication capabilities and safety features:

  • Rugged and lightweight design
  • Up to 31dB NRR (noise reduction rating)
  • Built-in rechargeable battery (lithium-ion)
  • VOX capable
  • Noise-cancelling boom mic
  • (IS) Intrinsically Safe                                                                                                                                                        TIA-4950-A, CSA C22.2 No. 157.92, & UL 913 5th Edition with a hazardous location rating of Class I, II, III,             Division 1 & 2, Groups A - G, T4 -20°C to +40°C, T3C -20°C to +50°C

Wow! It’s like having "Bionic Ears"!!! I was amazed when walking through the process area. I could even hear sounds that I did not know existed! Two weeks ago, I was in the process area when I received a call. I could not hear or understand the person on the other end of the line and they could not understand me. Today, I went to the same process area and was able to have a conversation. The person I was talking to thought I was sitting in an office. They said the clarity was "a hundred times better"!
