Use this TLV in the Resource Create (0x0124) and Generic Card Configure (0x0122) messages to set parameters for gating noise, including:
• the time constant over which the noise level is checked
• the allowable noise level
• noise gating sensitivity
If noise gating sensitivity is set too low for a conference, there is a risk of clipped speech; if it is set too high, there is a risk of noise bleeding through.
