The bass drum: The bass drum is one of the loudest of acoustic musical instruments. The largest bass drums used in marching bands have a diameter of 28 inches and a drum head that vibrates back and forth about a millimeter when struck firmly. (a) If the fundamental frequency of such a drum is 100 Hz, what approximately is the velocity of motion of the drum head? (b) Hence what is the sound pressure immediately adjacent to the drum head? And what is the intensity? (c) Given the diameter of the drum, what will its output power be (i.e., sound energy output per second). (d) Hence, about how loud will the sound be in decibels to a listener 5 meters away
