What dB level corresponds to a 500 Hz tone that is perceived to be at 40 phons?

Expert Solution

The lines on the graph in Figure 1 are referred to as equal loudness curves; each line is representative of a specific phon rating. The coordinate axes are the decibel rating and the frequency. To determine the dB rating of a sound with a given frequency and phon rating, one must first locate the point on the graph with the given phon rating where cut the 500h HZ axis...

from graph the the dB level greater than 40dB and near to 45 dB

A noise source produces sound mainly at 2500 Hz and an SPL of 95 dB at the location of a worker. In order to decrease this worker’s noise exposure, the employer decides to build a brick wall (? = 400 kg/m2) between source and worker. What would the sound level at the worker’s location be after the wall is built. Assume that the wall is perfect and that the sound must go through it (not around it).

Two test pilots are in identical jets that produce a characteristic tone of 507 Hz. One jet is stationary on the airstrip and the second is approaching the airstrip at a speed of 64.6% the speed of sound. Take the speed of sound in air to be 343 m/s. The pilot of each jet listens to the sound produced by the other jet. Determine the following. (a) Which pilot hears a smaller Doppler shift? the stationary pilotthe moving pilot (b)...
