Answer #1

sound pressure level, SPL = 20 Log (1) SPL = 9 dB. 9 = 20 log (P/P) 9 = log ( Ple) 0.us = log (P/Po) 2.8183 - £ change in pre

To understand the decibel scale. The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in W/m2 changes by a multiplicative factor. The number of decibels increases by 10 for a factor of 10 increase in intensity. The general formula for the sound intensity level, in decibels, corresponding to intensity I is β=10log(II0)dB, where I0 is a reference intensity. For...

Sound is often characterized by the decibel scale. 60 decibels is normal conversation and that corresponds to a sound pressure level of about 0.02 Pa. Consider the A-440 pure tone. This is a sine wave at 440 Hz with an amplitude of 0.02 Pa. If this wave travels through air at standard conditions, determine the wavelength of the wave, and variation of pressure, temperature, and density with time as one wave passes through a given receiving location. 4.
