- A sound wave enters the thin tube at P and exits at Q. Assume r = 0.50m and the wavelength is 1.12m. What is the smallest length d that results in constructive interference at Q?A round speaker emits sound waves uniformly in all direction. At a distance of 40.0m from the speaker, the sound intensity is 35 dB. What is the sound intensity level in a distance of 10.0m.The electrical power needed to operate a speaker in your audio system is 18.7 W. If this speaker has a circular opening with a radius of 0.0743 m and the average sound intensity at the opening is 22.1 W/m2, determine the ratio of sound output power Psound to electrical input power Pelectrical.
