For a sound source of intensity 
, corresponding sound level is 
decibel. If the intensity is increased to 4I, new sound level becomes:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
If intensity is doubled the sound level is increased by 3.0 dB. i.e., it becomes ( 
) decibels. Hence when intensity is increased four times, level becomes ( 
) decibels.
