Question 1158792: Loudness measured in decibels​ (dB) is defined by loudness=10 logr I Over ^I lower 0
​, where I is the intensity and I0=10 Superscript negative 12 ​W/msquared.
The noise level inside a convertible driving along the freeway with its top up is 80 dB. With the top​ down, the noise level is 97 dB. Find the intensity of the sound with the top up and the top down.

Loudness (L) in decibels (dB) is calculated as ,
where and is sound intensity in the same units.
Solving for :
--> --> -->
With the top up:
is the noise level inside a convertible,
so the sound intensity in is .
With the top down:
is the noise level inside a convertible,
so the sound intensity in is
(rounded).
