A flat piston of 0.15 m radius is mounted to radiate on one side of an infinite baffle into air at 330 Hz. (a) What must be the speed amplitude of the piston if it is to radiate 0.5 W of acoustic power? (b) If the piston has a mass of 0.015 kg, a stiffness constant of 2000 N/m, and negligible internal mechanical resistance, what force amplitude is required to produce this velocity amplitude?
