- A 38.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 38.0-Hz sound wave? What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 3.00 nm?A violin string of length L=31.8 cm and linear mass density µ=0.64gm/is tuned to play an A4 note at 440.0 Hz. This means that the string is in its mode of oscillation fundamental, that is, it will be on that note without placing any fingers on it. From this information, A. Calculate the tension in the string that will keep it in tune. B. If the midpoint of the string is observed to have a maximum transverse motion of 2.59 mm when in the fundamental mode, what is the maximum speed vy máx of the antinode of the string? C. If the string tension is reduced by 6.3% of the tension found in part A, what is the resulting frequency of the note produced? D. When playing the violin, different notes can be produced depending on the position of the fingers of one hand on the string. The usual technique presses the string hard against the fretboard, reducing the length of the string that can vibrate. If we consider this string initially tuned for an A4, and a finger is placed a third of the way down…As shown the two lowest resonances recorded in the vocal tract of the eastern towhee, a small songbird.a.

- a. A wooden flute, open at both ends, is 0.5 m long. Determine its fundamental vibration frequency assuming the speed of sound in air is 340 m/s b. How far from one end should a finger hole be placed to produce a sound whose frequency is 44 times that calculated in the first part.8. A "G" on a guitar has a frequency of about 196Hz. To raise the note to a "B" at 247 Hz, what length would the string have to be shortened to? Assume the original string is 1.0m long.The Wanamaker Pipe Organ in Macy's Center City department store in Philadelphia is the largest working pipe organ in the world. The organ occupies a seven- story hall, and has the longest pipe length of 9.75 m that occupies four floors and can be used as either an open or a closed pipe. Assume that the speed of sound is 345 m/s. a. Calculate the lowest fundamental frequency for the Wanamaker Pipe Organ. b. The highest note on an 88-key piano is 4186 Hz. What would be the length of a pipe open on one end that produced this as a fundamental frequency?
- The softest sound a human ear can hear is at 0 dB (Io = 10-12 W/m2). Sounds above 130 dB cause pain. A particular student's eardrum has an area of A = 51 mm^2. a. What is the most power, in watts, the ear can receive before the listener feels pain? b. What is the smallest power, in watts, the ear can detect?A thin 3.0-m metal rod sustains a longitudinal standing wave with vibration antinodes at each end of the rod. There are no other antinodes.
