A) When four quadruplets cry simultaneously, how many decibels greater is the sound intensity level than when a single one cries?

B) To increase the sound intensity level again by the same number of decibels as in part a), how many more crying babies are required?

**drwls**, Saturday, March 29, 2008 at 6:15pm(A_ Four babies have 4 times the intensity (sound power) as one baby. The decibel formula tells you the difference is 10 Log 4 = 6.02 dB.

(B) It will take another factor of four times as many babies (16 in all) to raise the sound level by another 6.02 dB.
