Tutorial: T13 - Perceptual and Physical Evaluation of Guitar Loudspeakers

Loudspeaker and headphones generate distortion in the reproduced sound that can be assessed by objective measurements based on a physical or perceptual model or just by a subjective evaluation performed in systematic listening tests. This tutorial gives an overview on the various techniques and discusses the way how measurement and listening can be combined by auralization techniques to give a more reliable and comprehensive picture on the quality of the sound reproduction. The separation of signal distortion in speech signals allows to assess signal distortion which are for most stimuli below the audibility threshold. Further analysis of the separated distortion signals gives clues to identify the physical root cause of loudspeaker defects which is very crucial for fixing design problems.
