A sound wave with an intensity level of 80.6 dB is incident on an eardrum of area 0.600 ✕ 10^-4 m². How much energy is absorbed by the eardrum in 4.0 minutes?
µJ?

A source of sound waves of frequency 1.2 kHz is traveling through the air at 0.55 times the speed of sound.

(a) Find the frequency of the sound received by a stationary observer if the source moves toward her.
Hz
(b) Repeat if the source moves away from her instead.
Hz

A trumpet creates a sound intensity level of 1.05 102 dB at a distance of 0.80 m. (a) What is the sound intensity of a trumpet at this distance? W/m2 (b) What is the sound intensity of five trumpets at this distance? W/m2 (c) Find the sound intensity of five trumpets at the location of the first row of an audience, 7.60 m away, assuming, for simplicity, the sound energy propagates uniformly in all directions. W/m2 (d) Calculate the decibel level...

Explain the di erence between sound intensity and sound intensity level in terms of what they measure You're listening to two speakers. One plays a 440 Hz tone, and the other plays a 442 Hz tone, both at the same volume. Name the kind of interference you'd hear, and describe how the volume of the sound you hear would vary, as speci cally as possible You're standing at rest on the oor. If you then rise up on your ptoes,...

READING 2 The eardrum is displaced surprisingly little when a sound wave strikes it. Some idea of the displacement of the eardrum by a sound wave can be obtained by using Equation 7.1: Equation for wave energy The displacement amplitude, A, of the air molecules gives us a lower limit to the displacement of the eardrum. At the threshold of hearing at 3.4 kHz, the sound intensity is about 10−12W/m2. The threshold of pain begins at an intensity of 1.0W/m2...

An audio system 1 produces a sound level of 90.0 dB and system 2 produces a sound level of 93.0 dB. (a) Determine the ratio of the intensities (in W/m 2 ) . (b) Suppose a recording device was placed 2 m away from s ystem 2 . H ow far away from system 1 must that recording device be placed in order for the intensity to be the same as it was near system 2?
