Perception and Evaluation of Audio
While there have been previous attempts to create metrics and formula that relate a series of acoustic factors to listener preference, no reliable method for prediction of quality has been univocally ascertained or included in any ISO standard. In this study an alternative perspective is presented - to derive a simple descriptor, ‘Preference Rating’ (PR), through meta-analysis of metric-preference relationships, within the context of Rock and Pop venues. A statistical approach has been taken to determine the relative importance of a chosen set of factors in the form of mathematical weights. A strong correlation was found for 85% of the halls tested. This demonstrates that the rationale behind such approach is meaningful and sets a base upon which further testing.
