Technical Notes for
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.
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.
