Audio Feedback can occur when a radio is used to make a group call whilst in close proximity to another radio/radio user. The audio coming out of the speaker feeds back into the mic. until nobody can hear anything except an unpleasant "howling" noise.
Motorola's MOTOTRBO Software fixes this issue. Using a sophisticated software algorithm, the radio is able to recognise the audio feedback from nearby radios and discard it. Now, there is no need for users to step away from their colleagues to make calls and there is no unpleasant howling noise disturbing customers.
