A violin plays with sound intensity of 63 dB as heard by a listener a distance of 21 meters away from the violin. How loud, in decibels, would the sound intensity be for the same listener if there were 4 identical violins playing? How loud, in decibels, would the sound intensity be for a single violin for a listener at distance of 57 meters?

A train traveling east at a speed of 25.0 m/s moving directlyawayfrom a stationary observer. a strong, steady wind of 20.0 m/sisblowing from east to west. At a distance of 50.0 meters awayfromthe observer, the train's whistle is blown and the observerhears afrequency of 500.0 Hz at an intensity level of 90.0dB.
a) what whistle frequency is heard by a passenger traveling onthetrain?
b) when 250 m away from the observer, the train's whistle isblownagain. calculate the sound intensity ( in decibels) heard bytheobserver.
c) during 10.0 seconds how many Joules of sound-wave energy doesthewhistle transfer into the air?
d) due to the wind, the frequency heard by the observer is (greaterthan, less than, the same as) the frequency she would hearif therewas no wind. explain the answer.

Two 350.0-W speakers, A and B, are separated by a distance D = 3.41m. The speakers emit in-phase sound waves at a frequency f =11800.0 Hz. Point P1 is located at x1= 4.51 m and y1 = 0 m; pointP2 is located at x2 = 4.51 m and y2 = –?y.
a) Neglecting speaker B, what is the intensity, IA1 (in W/m2), ofthe sound at point P1 due to speaker A? Assume that the sound fromthe speaker is emitted uniformly in all directions.
b) What is this intensity in terms of decibels (sound level,ßA1)?
c) When both speakers are turned on, there is a maximum in theircombined intensities at P1. As one moves toward P2, this intensityreaches a single minimum and then becomes maximized again at P2.How far is P2 from P1, that is, what is ?y? You may assume that L>> y and that D >> y, which will allow you to simplifythe algebra by using (a±b)1/2 ˜ a1/2 ± 0.5b/a1/2 when a >> b.

Dolphins emit sound bursts that range in frequency from 1 Hz to 120kHz. Say that a dolphin is using a sound burst consisting of thesefrequencies as a form of sonar (like the bat example). Let theburst last for a time interval of 10 ms, after which it listens for100 ms. Say that the logarithmic intensity (loudness) of thedolphin’s sound is 50 dB as measured at 1 m away. Dolphins can hearsounds that are 2 dB below our threshold of hearing.

a. How far ahead can the dolphin “see” using this approach?

b. What is the smallest object that the dolphin can ‘see’?

c. What is the largest object that the dolphin can ‘see’?

d. What would be the amplitude of the pressure wave at 20 m fromthe dolphin?

e. How far from the dolphin producing the sounds does anotherdolphin have to be before the sound intensity is below thethreshold of hearing for dolphins?
