Delivered Audio Quality, abbreviated as DAQ, is a measure of audio quality over a transmission medium. This metric is often used to quantify the quality of audio heard over a radio system. DAQ levels are defined by the following scale.
* DAQ 1: Unusable. Speech present but not understandable.
* DAQ 2: Speech understandable with considerable effort. Requires frequent repetition due to noise or distortion.
* DAQ 3: Speech understandable with slight effort. Requires occasional repetition due to noise or distortion.
* DAQ 3.4: Speech understandable without repetition. Some noise or distortion present.
* DAQ 4: Speech easily understandable. Little noise or distortion.
* DAQ 5: Perfect. No distortion or noise discernible.
