From hi-fi to PA: predicting and measuring what we hear
(MP3 Audio - Length: 1:43:17)
Everyone wants 'high quality' sound — but what does this mean -- is sound quality measureable? is it predictable? The talk will look at how we can assess sound quality — both in large spaces such as concert halls, cathedrals and even railway stations as well as in small rooms such as home theatres and hi-fi listening spaces. After introducing a number of parameters and concepts that affect sound quality and the listening experience, Peter will discuss how these can be measured and potentially predicted. In particular the use of 3D computer modeling of rooms will be highlighted together with the importance of bass frequency reproduction. A number of case studies and examples of problem sound systems/rooms will be presented. Peter will conclude the talk with an insight into some of his latest research and the introduction of a new measurement/assessment concept, SQI — the Sound Quality Index.
