A sound source, from the nearby construction site, repeatedly makes a sound for 5 minutes, at the frequency of 125 Hz, and then stops for 10 minutes. The noise source is emitting noise in the evening hours during the working days. The source is located in the corner of two flat surfaces perpendicular to each other, as shown in figure below. The recorded sound level 100 m away from the point source is 56 dB. The sound level was recorded using Z-weighting network. 1000 m away from the point source, there is a village as noise sensitive receiver (NSR). The noise level at the NSR is noticeable, but not dominant feature of the noise climate (indirectly affected).

Will the Leq (20 min) received by the NSR during the evening exceed 65dB?

Expert Solution

Hence Leq(20min) at a 1000 m away is 32.98dB.

And it will not exceed 65dB.

Problem 6: Two students are standing the same distance from a source of sound. The first student receives a power of 246 × 10-6 W in their eardrum. The second student receives σ = 1.17 times more power in their eardrum. Part (a) What is the ratio of the diameters of the student's eardrums? Part (b) If the second student's eardrum has a diameter of d = 1 cm what was the intensity of the sound that the student heard,...

Suppose that when you’re 12 ft away from the source of a sound, it’s intensity is 3 X 10^-6 W/m^2, If you move so that you are now 6ft away from the source of the sound, what is the intensity? If you move again so that now you’re 24 ft away from the source of the sound, what is the intensity? At what point do you perceive the sound as having the highest amplitude?
