Answer: the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.

Explanation: Given that sound at a rock concert power is 130 dB of intensity l2

a whisper power is 2 dB of intensity l1

Using the formula

130dB – 2dB = 10Log(I2/I1)

128/10 = logI2/I1

12.8 = log (I2/I1)

I2/I1 = 6.31 × 10^12

Therefore, the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
