what length of open pipe will produce a frequency of 1200 Hz as it first overtone on a day when the speed of sound is 340 m/s

A bat traveling at a speed of 18.1 m/s sends out sound at a frequency of 48.2 kHz, can 'see' objects due to echolocation. What frequency would the bat hear returning from a stationary wall in front of it? (assume the speed of sound in air is 343 m/s)

The sound level 23.8 m from a loudspeaker is 66.7 dB. What is the rate at which sound energy is produced by the loudspeaker, assuming it to be an isotropic source?

The scream of a little screaming monster reaches the near-side of a sound-insulating wall with an intensity of 95 dB.   The manufacturer of the wall claims the material in the wall will reduce the sound energy by 99%. If this is true, what intensity, in decibels, of sound will be heard on the other side of the wall?

The tension in a nylon monofilament fixed at both ends is 23.0 N. The mass per unit length is 5.00 x 10-3 kg/m, and its length is 37.0 cm. (a) What is the fundamental frequency (in Hz)? Hz (b) What are the next three frequencies (in Hz) that could result in standing wave patterns? List them smallest to largest. second harmonic Hz third harmonic Hz fourth harmonic Hz Need Help?

A sound wave arriving at your ear is transferred to the fluid in the cochlea. If the intensity in the fluid is 0.410 times that in air and the frequency is the same as for the wave in air, what will be the ratio of the pressure amplitude of the wave in air to that in the fluid? Approximate the fluid as having the same values of density and speed of sound as water. Speed of sound in dry air (20.0°C, 1.00 atm) is 343 m/s, density of dry air (at STP) is 1.29 kg/m3, density of water is 1000 kg/m3, and speed of sound in water is 1493 m/s.

What is the speed of sound in (m/s) in a medium where a 156 KHZ frequency produces a 3.282 cm wavelength?

What is the length of the shortest pipe open at both ends that will have a fundamental frequency of 0.060 kHz on a day when the speed of sound is 344 m/s?

A sound wave radiates from a speaker in all directions. If the power of the sound source is 200 W, calculate the intensity level in dB of the sound wave 1 km from the speaker. Hint: Presume that the sound waves spread as a sphere (not a hemisphere).

An organ pipe that is open both ends has a fundamental frequency of 382 Hz at 0 ° C. Calculate the fundamental frequency for this pipe at 35 ° C.
