A frequency generator (a device that produces sinusoidal signals whose frequency and amplitude can be independently set)
Question:
A frequency generator (a device that produces sinusoidal signals whose frequency and amplitude can be independently set) is used to power a horn. The frequency is set to \(2000 \mathrm{~Hz}\), and for a particular amplitude the sound intensity is measured to be \(0.050 \mathrm{~W} / \mathrm{m}^{2}\) at a distance of \(12 \mathrm{~m}\).
(a) What is the power output of the horn in this case?
(b) If the power output is increased to \(92 \mathrm{~W}\), what is the new intensity reading?
