[From: ] [author: ] [Date: 12-01-07] [Hit: ]

10dB is 10 times greater than 0dB. 20dB is 100 times greater than 0dB. 50dB is 10,000 times greater etc.So 25 - 5 is 20 and 20 / 10 = 2 so 25dB is 100 times more intense than 5dB-100x the power level in watts/sq metre-C-5x more intense,-E.......

A. 32 times
B. 100,000 times
C. 5 times
D. 20 times
E. 100 times

E.

Every increase of 10 is 10 times.

For example, 10dB is 10 times greater than 0dB. 20dB is 100 times greater than 0dB. 50dB is 10,000 times greater etc.

So 25 - 5 is 20 and 20 / 10 = 2 so 25dB is 100 times more intense than 5dB
