Comb-Filter Effects

The effect of a delayed reflection on the frequency response of a signal is often called a comb filter. Comb filtering is a steady-state phenomenon. It has limited application to music and speech, which are highly transient phenomena. With transient sounds, the audibility of a delayed replica is more the result of successive sound events. A case might be made for combing effects during brief periods of speech and music that approach steady state. However, the study of the audible effects of delayed reflections is better handled with the generalized threshold approach of sound reflection. Still, it is important to ...
