The low-frequency speaker of a stereo set hag a surface area of 0.05 m2 and produces 1W 0f acoustical power. What is the intensity at the speaker? If the speaker projects sound uniformly in all directions, at what distance from the speaker is the intensity 0.1W/m2 ?
Suppose a person has a 50—UB hearing loss at all frequencies. By how many factors of 10 will low—intensity sounds need to be ampli?ed to seem normal to this person? Note that smaller amplification is appropriate for more intense sounds to avoid further hearing damage.
What are the closest frequencies to 500 Hz that an average person can clearly distinguish as being different in frequency from 500 Hz? The sounds are not present simultaneously.
Scouts at a camp shake the rope bridge may have just crossed and observe the wave crests to be 8.00 m apart. If they shake it the bridge twice per second, what is the propagation speed of the waves?
Ultrasound reflected from an oncoming bloodstream mat is moving at 30.0 cm/s is mixed with the original frequency of 2.50 MHZ to produce beats. What is the beat frequency? (Assume than the frequency of 2.50 MHz is accurate to seven significant figures.)
Due to eficiency considerations related to its bow wake, the supersonic transport aircraft must maintain a cruising speed that is a constant ratio to the speed of sound (a constant Mach number]. If the aircraft flies from warm air into colder ail, should it increase or decrease its speed? Explain your answer.
(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).
Can the average person tell that a 2002-Hz sound has a different frequency than a 1999-Hz sound without playing them simultaneously?
What is the ratio of intensi?es of two sounds of identical frequency if the first is just barely discernible as louder to a person than the second?
Show mat the speed of sound in 20.0°C air is 343 m/s, as claimed in the text.
Is it realistic to approximate that the propagation of sound waves is an isentropic process? Explain.
3. A motorist approaching a vertical wall observes that the frequency of his motor horn changes from 380 Hz to 430 Hz when it gets reflected from the wall. Find the speed of the motor in mps if the speed of sound is 330 mps.
