Internal Mic Background Noise Reduction Level Selection |
(Radio Profiles, Audio Settings) |
Selects the level of background noise reduction that is applied to the internal dual-microphones. This selection applies to the current Radio Profile.
|
Noise Reduction improves voice clarity by reducing background noise. Noise Reduction occurs on the transmitting radio prior to transmission (in analog mode) and prior to voice coding (in digital mode). Not only does reducing background noise improve voice clarity for an analog mode transmission, in digital mode a cleaner speech signal going into the voice-encoder (vocoder) results in clearer voice being received and decoded in the receiver. |
When the Custom Internal Mic Noise Reduction Enable field is disabled.
Off |
Disables dual-microphone background noise reduction. Both microphones remain active, and the radio-user can speak into either side of the radio, but no background noise reduction is applied. |
Normal |
Both microphones are active and continuously adapt to the voice signal for optimal clarity over a wide range of background noise. Recommended setting for most noise environments. |
Aggressive |
An increased level of background noise reduction is enabled. Recommended for VERY HIGH noise environments. |
Xtreme 1_Sided |
The Maximum amount of background noise reduction is enabled. Recommended for EXTREME HIGH noise environments, for example: Firefighter PASS (Personal Alert Safety System) alarm, low air alerts, pumper truck, gas fan, saw.
