1. When a sound wave passes through air, and we hear it, the air pressure where we are varies with time. the excess pressure above (and below) atmospheric pressure in a sound wave is given by the graph below: p(t) t in seconds -1 (a) Show that the fundamental (n ) is 15 times smaller in amplitude compared to the second harmonic (n-2). Hint: Expand p() in a Fourier series to show this. It would be interesting to note that...

2) (8 points) Show your work for full credit. An omnidirectional loudspeaker produces sound waves uniformly in all directions. A sound intensity of 100 W/mºis measured 1.0 m from the speaker. (a) How far from the speaker will the sound intensity be measured to be 1.0 W/mº? (b) At what distance from the speaker will the sound intensity level be 100.0 dB?

4. Your ears detect a sound wave with a frequency of 315 Hz and a sound intensity level of 80 dB. It originated in a vibrating string with a length of 1.9 meters. A) Waves can be longitudinal or transverse. What is the difference between these two kinds of waves? B) This question has one longitudinal wave and one transverse wave. Identify them. C) Recall that the sound you hear from a string is the fundamental frequency, which has a...

Please answer. Thank you!
The following problems are each worth 4 points. There is partial credit. Please show all work including equations Do not forget units. Please place the answer in the box provided. 7. Suppose that a public-address system emits a 494 Hz sound uniformly in all directions. (a) If the air temperature is 25°C (sound travels at 346 m/s), what is the wavelength of this sound? (b) If the intensity at a location 22 m away from the...

7. If the acoustic intensity level increases by 6dB, by what factor does the sound (acoustic) intensity increase? What about a 9dB increase? What about a 12dB increase? NOTE: If we know the SPL (Li) or a sound at a distance di, we can work out the SPL (L2) at another distance, d2, from L2-L1 20 log1o
