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

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?
