In our listening rooms reflected sounds – sounds that bounce off walls and other objects – are more often louder than the direct sound from our loudspeakers. Nyal Mellor and Jeff Hedback explain how reflections affect our perception of sound, and how the Energy-Time Curve (ETC) can be used to assess the nature of reflections in a given listening room.
This article by Nyal Mellor introduces three fundamental acoustical issues that room correction cannot address. They can only be addressed through good design, appropriate use of acoustic treatment, and appropriate system setup techniques.
