- A freight train coming down the tracks has a sound level of 88 dB, while the sound of the birds chirpingnear the train have a sound level of 32 dB. How many times louder is the sound of the train than the soundof the birds?When an object approaches you at Ma = 0.8, you can hearit, according to Fig. But would there be a Dopplershift? For example, would a musical tone seem to you tohave a higher or a lower pitch?14. A cannon is fired from a distant hilltop and you see the smoke followed by hearing theexplosion. Calculate how far away the cannon is if the temperature on the day this is observedis 18 o(degree)C and time between the smoke and the sound is 4.7 s.
- A drainage pipe running under a freeway is 33.0 m longBoth ends of the pipe are openand wind blowing across one end causes the air inside to vibrate What the frequency of the lowest harmonic that would be audible to the human ear? The frequency we can hear is about 20 Hz)?The noise of a jackhammer at a distance of 100 m has sound intensity of 100 dB. Assume the inverse square law is valid. Calculate and select the correct sound level of four such jackhammers at 200 m.The longitudinal oscillations of air layers in sound wave propogation are consistent with the random thermal movement of molecules in air. Explain.
- Calculate the wavelength (in m) of a 950.00 Hz sound in air at room temperature and pressure, where the velocity of sound is 344 m/sAt an outdoor music event, a dB meter records 130 dB when placed 2.25 m in front of aloudspeaker near the stage. A) What was the power output of the speaker, assuminguniform spherical spreading of the sound and neglecting any absorption, reflection andinterference of the sound that may occur? B) How far away would you need to be forthe sound level to be 80 dB?Two speakers are placed next to one another, D = 2.45 meters apart. They both emit a singlenote, A, which has a frequency of 560 Hz. A person stands directly in line with the two speakers, asshown. What is the minimum distance, d, away from the speaker on his left that he should stand sothat will he will no longer hear the note?
