Answer:
The expression that shows a valid step in
the process of finding the decibel level of the noise is dB = 10 log 150,000. Option C is correct
Given the equation for calculating the intensity of sound which is measured in decibel expressed as:
dB=10 log l
where;
I is the ratio of the sound to the human hearing threshold
Given that noise is 150,000 times greater than the human hearing threshold.
Substitute | = 150,000 into the expression above;
dB = 10 log 150,000
If this is correct, brainliest please.
