Abstract:
Subjective measurements (i.e., listening tests) on audio components and systems are time-consuming, expensive and challenging to conduct in a controlled way that produces meaningful results. The alternative is to rely entirely on objective measurements that are then interpreted by the engineer based on his/her experience in order to estimate perceived sound quality. In recent years, there have been several attempts to predict the sound quality ratings of listening tests based on objective measurements. Various models based on objective measurements have been developed to predict the perceived the perceived sound quality of audio components and systems including audio codecs, loudspeakers, headphones, automotive audio systems, and listening rooms. This workshop will give an overview of some of the challenges and limitations researchers face in developing models, discuss how accurate they are with some specific examples given from experts in the field. The workshop should be of interest to any professional or enthusiast interested in the perception and measurement of sound quality
