All models are equipped with noise canceling electret microphones that provide a 20 dB (90%)
reduction in transmitted background noise.
The circumaural earcups on Model SHR 2082 & Model SHR 2083 provide a Noise Reduction Rating
(NRR) of 22 dB.
Headsets are fitted with Plantronics Quick Disconnects (QD) which allow the user to easily detach the
headset from the interface cable.
Model SHR 2376 can be worn with helmets or other headgear.
The cables feature robust polyurethane (PU) jacketing material. They are resistant to UV, oil and
solvents. They remain flexible over a wide range of temperature extremes.
All models feature adjustable headbands & microphone booms.
Custom versions available upon request.

Circumaural Earcups:
The Noise Reduction Rating (NRR) of the Ruggedized Headsets is 22 dB.
The level of noise entering the users ear when the headset is worn as directed is approximated by the
difference between the A-Weighted environmental noise and the Noise Reduction Rating (NRR) of the
headset. For example: If the environmental noise level as measured at the ear is 92 dBA, and the NRR of the
headset is 22 dB, then the resulting level of noise entering the ear is approximately 70 dBA.The headset
must be properly worn to attenuate noise effectively.
Refer to ANSI S12.6-1984

Microphone:
The microphone reduces transmitted background noise by 20 dB.
The high quality gooseneck boom allows the microphone to easily be positioned in front of the mouth.
The distance between the front and rear ports reduces the sensitivity at 1 KHz to far field noise by 15 dB
compared to close talking response. Compared to on-axis voice, the bi-directional response reduces 90
degree incident noise by 20 dB more and random noise by 5 dB more.The bandpass is limited to 5 KHz
and it acoustically filters the higher frequencies which are unwanted on most communication systems.
