How many times louder is a 120-dB sound than a 30-dB sound?
Homework Answers
Each 10 db increases the loudness by 2 times.
Decibel
Value
Increase in Sound Intensity Perceived
Increase in Volume
30 dB Base
40 dB 10 2
50 dB 100( 10*10 ) 4
60 dB 1000 8
120 dB
So, 120dB is 512 times louder than 30dB

9. Sound levels are measured by the logarithmic decibel scale, named after Alexander Graham Bell. The sound level, L, corresponding to an intensity of I, in watts per square metre, is し= 10 log-, where lo is the minimum intensity audible to the human ear. If amplified rock music has a loudness of 120 dB and ordinary conversation has a loudness of 50 dB, how many times louder than ordinary conversation is amplified rock music?
