Such an infinite baffle results in a 6 db, or 2×, boost in sound pressure as compared with a non-baffled loudspeaker. Under these circumstances, someone standing behind the baffle hears essentially no sound, while someone standing in front of the baffle hears essentially twice the sound volume as compared to the sound output without this “infinite baffle” effect. A baffle appears to be of infinite size if the baffle limits the radiation pattern of the loudspeaker from 360 degrees to 180 degrees.
The enclosure to which the loudspeaker is mounted acts as a baffle, where the dimensions of the baffle determine the range of frequencies at which the baffle is effective.
of the enclosure itself by means of the enclosure structure, i.e. standing waves within enclosure, or of undesired vibrations, i.e.
