The best loudspeakers for stereo sound reproduction are those that disappear chameleon-like from the listening room and simultaneously withdraw attention from the room. This effect is used in constructing speakers and their enclosures, to ensure that the maximum of output energy is passed to the listener. Baffle Diffraction Versus Neutral Sound Dispersion Presentation at Burning Amp - 2017. The baffle forestalls the diffraction and thus reduces the magnitude of the interference. ![]() An acoustic radiator must be specially designed for good dispersion of high frequencies since this does not occur naturally through diffraction. In the absence of the baffle, these sounds both diffract in all directions, and, because they are exactly out of phase they interfere destructively, especially the bass. As a result of their capability of diffraction, low frequency sounds are difficult to localize or contain in an environment (see CANYON EFFECT, DIFFUSE SOUND FIELD). When the speaker is held up behind a hole the size of the speaker in a board about two feet square, the sound becomes much louder to the audience this is particularly noticeable in the lower (bass) frequencies.Ī loudspeaker produces two distinct sound waves: one from the front and one from the back, which are out of phase with respect to each other. Purpose: Demonstrates diffraction and interference of sound wavesĪ small loudspeaker plays music with lots of bass, but the bass is not very loud. ![]()
