As you increase the decibel level from 80 dB to 100 dB, the sound pressure ratio goes from _____ to _____.
A) 80; 100
B) 800; 1000
C) 100; 1000
D) 10,000; 100,000

Question

Quizplus · Accepted Answer

The decibel scale is logarithmic, with every 20 dB increase representing a tenfold increase in sound pressure ratio. Therefore, going from 80 dB to 100 dB multiplies the sound pressure ratio by 10, moving from 10,000 (for 80 dB) to 100,000 (for 100 dB).
