Consider two sounds
whose sound level differ by 37 dB. Find the ratios of
a. the intensities,
b. the pressure amplitudes, and
c. the particle displacement amplitudes.
a.The intensity ratio is
The difference between the two sound levels
In our case
that is the pressure amplitude is proportional to the square root of the
b.The pressure amplitude ratio is .
c. The ratio of
the displacement amplitudes is equal to the ratio of pressure amplitudes.
c.The displacement amplitude ratio is
