The intensity of sound is measured on the decibel scale, dB. The equation dB = 10 log I represents the decibel level,
where I is the ratio of the sound to the human hearing threshold.
A noise registers a decibel level of 29. Which equation could be used to find how many times greater the noise is than the
human hearing threshold?
Select the correct answer below:
a) 1 – 1020
b) I = log 2.9
c) 1 – 1029
d) I = log 29
e) I = 2.910
