Question 23372: My assignment was to figure out the formula for measuring sound, and to pick a specific sound, and give the decibels of the sound and explain what this measurement means. I don't even know how to begin.

Use your Google search to look at "Sound frequency decibel"
separately or in combination.
Human sound is between 20hz and 20khz.
For example, for a frequency of 45hz the sound wave formula is
y = sin [(2pi/45)x].
Intensity of sound expressed in dB = 10log [(sound intensity/threshold ]intensity). The threshold is a certain level of intensity that physicists
use as a measuring unit to determine the dB measurement of a sound they
are studying.
For example a Rock Concert has been measured as having a dB level between
102 and 106 dB
Put that 102 into the formula and you get the following:
102dB =10log[Intensity/threshold]
10^101 = Intensity/ threshold
Sound intensity of the concert is (10^101)*(threshold intensity)
That is LOUD.
Cheers,
Stan H.
