For a sound source of intensity `IW//m^(2)`, corresponding sound level

1.	For a sound source of intensity `IW//m^(2)`, corresponding sound level is `B_0` decibel If the intensity is increased to `4I`, new sound level becomes.A. `2B_(0)dB`B. `(B_(0)+3)dB`C. `(B_(0)+6)dB`D. `4B_(0)dB`
Answer» Correct Answer - C If intensity is doubled the sound level is increased by `3.0dB`. i.e., it becomes `(B_0+3)` decibels. Hence when intensity is increased four times, level becomes `(B_0+6)`
