- You are standing directly between two loudspeakers playing identical 350 Hz tones. Describe what you will hear if you start walking along a line perpendicular to the line between the speakers.A single goose sounds a loud warning when an intruder enters the farmyard. Some distance from the goose, you measure the sound level of the warning to be 88 dB. If a gaggle of 20 identical geese is present, and they are all approximately the same distance from you, what will the collective sound level ßeaggle be if they all sound off simultaneously?

- An observer hears a sound from a vehicle that is parked. Then, the vehicle starts moving toward her. What will happen to the frequency and wavelength of the waves when the vehicle starts moving toward her? Your answer: The frequency and wavelength will both increase. The frequency and wavelength will both decrease. The frequency will increase and the wavelength will decrease. The frequency will decrease and the wavelength will increase.Sound travels at an estimated speed of 344 * m/s c a sound wave has a frequency of 2500 HzWhat is the distance between the crests of each wave?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/s
