An interstate highway has been built through a neighborhood in a city. In the afternoon, the sound level in an apartment in the neighborhood is 80.0 dB as 100 cars pass outside the window every minute. Late at night, the traffic flow is only five cars per minute. What is the average late-night sound level?
As a certain sound wave travels through the air, it produces pressure variations (above anti below atmospheric pressure) given by P = 1.27 sin (x - 34t) in SI units. Find (a) the amplitude of the pressure variations. (b) the frequency, (c) the wavelength in air. and (d| the speed of the sound wave.
As the people sing in church, the sound level everywhere inside is 101 dB. No sound is transmitted through the massive walls, hut all the windows and doors are open on a summer morning. Their total area is 22.0 m2. (a) How much sound energy is radiated through the windows and doors in 20.0 min? (b) Suppose the ground is a good reflector and sound radiates from the church uniformly in all horizontal and upward directions. Find the sound level 1.00 km away.
(a) Ear trumpets were never very common, but they did aid people with hearing losses by gathering sound over a large area and concentrating it on the smaller area of the eardrum. What decibel increase does an ear trumpet produce it its sound gathering area is 900 cm2 and the area of the eardrum is 0.500 cm2, but the trumpet only has an eficiency of 5.00% in transmitting the sound to the eardrum? (b) Comment on the usefulness of the decibel increase found in part (a).
