The intensity of sound during the festival season increased by 100 times. This could imply a decibel level rise from -

A

20 to 120 dB

B

70 to 72 dB

C

100 to 10000 dB

D

80 to 100 dB

Text Solution

Verified by Experts

The correct Answer is:
D
Sound intensity `=10log_(10)((l_(1))/(I_(o)))impliesI=100I_(o)`
`implies 10xxlog"(100i_(0))/(i_(0))=20`
So, level rises by 20dB.
