The Haas effect, which is also known as the precedence effect, is something every audiophile needs to know about. It’s a psychoacoustic phenomenon discovered and written about by Dr. Helmut Haas in 1949, in which sounds from multiple sources are heard as one sound if they arrive to our ears within a short enough time window.
The effect is well known to recording and mixing engineers, since it’s used when making recordings, but it’s also crucial in other areas of sound reproduction, such as when a loudspeaker is playing in a room. The latter is what Doug Schneider mostly focuses on in this video, since understanding this phenomenon is important when it comes to selecting and setting up speakers for maximum performance and musical enjoyment.
