Audio Equipment And Stage Lighting News The elementary phenomena of sound were the subject of much speculation among ancient peoples; however, with the exception of a few lucky guesses, little was known about the science of sound until about 1600. Starting at that time, the knowledge of sound increased more rapidly than knowledge of the corresponding phenomena of light, because the latter are more difficult to observe and measure.

Other types of enclosures attempt to improve the low frequency response or overall efficiency of the loudspeaker by using various combinations of reflex ports, transmission lines and horns. The parts are held together by a chassis or basket. These noises can be eliminated by proper design and construction. Although electrically out of phase with one another, the drivers are acoustically in phase since they move in the same direction. Fm, television, and other very-high-frequency broadcasts must have very high antennas if appreciably long range is to be achieved, and it may not be convenient to locate such a high antenna near the broadcasting studio. Airplane and automobile radio sets that operate on 12 to 24 volts dc often contain circuits that convert the available dc voltage to ac, after which the voltage is stepped up or down to the required voltage level and again converted to dc by a rectifier.
