Background Noise Reduction Level

(Radio Profiles, Audio Settings)

Selects the level of background noise reduction that is applied to the internal dual-microphones and an external microphone. 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 Noise Reduction field is disabled.

The following table lists the selections and definitions for Background Noise Reduction Level (Radio).

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.	N/A
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. This Setting requires the radio-user to speak into the side of the radio containing the large loudspeaker. This selection applies only when the radio is model / option capable.	N/A
Auto	Enables the auto-aggressiveness profile of noise reduction. This selection applies only when the radio is model / option capable.	N/A

The following table lists the selections and definitions for Background Noise Reduction Level (Accessory).

Off	Disables background noise reduction. The external microphone remains active, but no noise reduction is applied.
Normal	The external microphone continuously adapts 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 alarm, low air alerts, pumper truck, gas fan, saw. This Setting requires the radio-user to speak into the side of the radio containing the large loudspeaker. This selection applies only when the radio is model / option capable.
Auto	Enables the auto-aggressiveness profile of noise reduction. This selection applies only when the radio is model / option capable.
