Find the intensity in decibels [I(dB)] for each value of I.
Normal conversation: I = 106I0
I(dB) =
The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation
I(dB) = 10log
I
I0
where I is the intensity of a given sound, and I0 is the threshold of hearing intensity.
The human ear is just able to notice a 1 dB difference in sound intensity.
Power saw a 3 feet: I = 1011I0
I(dB) =
Jet engine at 100 feet: I = 1018I0
I(dB) =
