An enclosed chamber with sound-absorbing walls in Chamberlin Hall has a 2.0m x 1.0m opening for an outside window. A loudspeaker is located outdoors, 87 m away, and facing the window. The intensity level of the sound entering the window space from the loudspeaker is 79 db. Assume the acoustic output of the loudspeaker is uniform in all directions and that the acoustic energy incident upon the ground is completely absorbed and therefore is not reflected into the window. The threshold of hearing is 1.0 x 10 -12 W/m2. What is the acoustic power entering through the window space

In Figure OQ14.3, a sound wave of wavelength 0.8 m divides into two equal parts that recombine to interfere constructively, with the original difference between their path lengths being |r2 − r1| = 0.8 m. Rank the following situations according to the intensity of sound at the receiver from the highest to the lowest. Assume the tube walls absorb no sound energy. Give equal ranks to situations in which the intensity is equal. (a) From its original position, the sliding section is moved out by 0.1 m. (b) Next it slides out an additional 0.1 m. (c) It slides out still another 0.1 m. (d) It slides out 0.1 m more. Figure OQ14.3
A sound wave in air has a pressure amplitude equal to 4.00 103 Pa. Calculate the displacement amplitude of the wave at a frequency of 10.0 kHz.
Some studies suggest that the upper frequency limit of hearing is determined by the diameter of the eardrum. The wavelength of the sound wave and the diameter of the eardrum are approximately equal at this upper limit. If the relationship holds exactly, what is the diameter of the eardrum of a person capable of hearing 20 000 Hz? (Assume a body temperature of 37.0C.)
A sound wave can be characterized as (a) a transverse wave, (b) a longitudinal wave, (c) a transverse wave or a longitudinal wave, depending on the nature of its source, (d) one that carries no energy, or (e) a wave that does not require a medium to be transmitted from one place to the other.
Sound is passing perpendicularly through an open window whose dimensions are 1.1 m × 0.75 m. The sound intensity level is 95 dB above the threshold of hearing. How much sound energy comes through the window in one hour?
A concert loudspeaker suspended high off the ground emits 35 W of sound power. A small microphone with a 1.0 cm2 area is 50 m from the speaker. What are (a) the sound intensity and (b) the sound intensity level at the position of the microphone?
After years of being alone and never getting a single phone call, Daniel understandably forgets to shut off his cell phone in class. One miraculous day, he finally receives a call and accidentally allows the ringer to emit sound waves uniformly in all directions. At a distance of 13.0 m. from the source, Mr. O''Hara's sensitive ears observe the intensity level to be 94.0 dB. What is the total acoustic power output of the cell phone speaker, in watts?
A listener is standing on a ground that is non-absorbing. Situated at a distance from the listener are two sound sources such that: source A has a sound power of 5 W and 15 m from the listener and source B has a power of 15 W and 25 m from the listener. What is the sound pressure level the listener would hear
A sound wave having a frequency of 253 Hz travels through air at 20 °C. The decibel level at a distance of 32.2 m from the source is measured to be 77.1 dB. What is the dB level at a position that is 14.1 m closer? Assume the density of air is 1.20 kg/m3 and that the source produces spherical wave fronts.
A certain source of sound waves radiates uniformly in all directions. At a distance of 20 m from the source the intensity level is 51 db. What is the total acoustic power output of the source, in watts? (Note: The reference intensity 10 is 1.0 × 10 12 W/m².) Give your numerical answer in Watts.
Two loudspeakers produce the same pure-tone sound (that is, same frequency). A sound detector is placed at a distance of 5.00 m and 5.40 m from the two loudspeakers, respectively. The two tones interfere destructively, so that no sound is picked up by the detector. What is the frequency of the tones? Take the speed of sound to be 344 m/s, as usual.
A sound wave travels through air at 20 °C. The decibel level at a distance of 19.4 m from the source is measured to be 85.2 dB. What is the dB level at a position that is 7.17 m closer? Assume the density of air is 1.20 kg/m3 and that the source produces spherical wave fronts.
