Generally, evaluation of sound quality of audio systems or AV products is accomplished through listening tests with groups of trained listeners, each having subjective views. But these kind of methods often tend to give results that are distorted due to listening environments and personal preferences of the listeners. For these reasons, even though they are deeply related to the way listeners actually hear things, subjective listening tests contain problems such as inaccuracy and time/place dependency. By examining the correlation between objective measurable evaluation factors and subjective listening test items, this paper proposes an objective method for sound quality evaluation that is based on former subjective methods for audio systems and AV products.
