Question

1.)

A.) 4.5

B.) 1.5

C.) 3.5

D.) 2.5

Answer 1

So Brin M.,

Just assign L2 = 97 dB and L1 = 93 dB. Plug in to the definition equation, and ratio the two equations. That gives you: 97/93 = 10 log (L2/Lo)/10log (L1/Lo) . I'm betting that you know a little bit about how to unpeel L2/L1 from this equation?
