more often than not people lump comb filtering and acoustical interference together as the same phenomena. Comb Filtering: This is basically a delayed version of a primary signal that is produced when two or more loudspeakers are playing the same signal at different distances from the listener.In any enclosed space such as a music or theater room, listeners hear a mixture of direct and reflected sound.his is why the term âacoustical interferenceâ which is really a subset of comb filtering is generally applied to the behavior of a particular speaker, whereas âcomb filteringâ is applied to the behavior of a set of speakers.
