Objective quality assessment for the acoustic zoom

Sound quality is a major issue of concern for all modern telecom and audiovisual systems. The evaluation of sound quality includes both objective and subjective methods. The subjective methods reflect the listeners perception of the sound and the objective methods try to evaluate the sound parameters affecting its quality in correlation with the results of the subjective methods. The subjective tests are time consuming, which is inconvenient during the development of new algorithms of audio signal processing and tuning its parameters. This article investigates the possibility of applying objective methods for audio quality assessment on an acoustic zooming system and it compares their results and the results of the subjective intelligibility test.
