If only there was real progress on the interdiscipline communication discussed here. Common language and terminology indeed. PRaT exemplifies the huge divide between engineers and audiophiles. Is one listener's essential spec another's poster child for horsecrap? You bet. Since the STEM people will - or will not - produce the real improvements we desire, a common lexicon to describe audio would be of huge value. I am in favor of using the engineering language, but the audio equipment reviewers would have an arrow aimed at my heart if I became vocal about it.
