I have been trying to solve this question for ages now... I know the answer but cannot figure out how they get there.
In acoustics, decibels are used to measure sound pressure according to the law L = 10log10P12 - 20log10P0.
Given that P0 = 2 x 10-5 and P1 = 2000 for a rocket launcher, calculate the sound pressure L, created by the rocket launcher.
I have tried to move things around in every possible way and I'm sure I'm just missing something. The answer is 160 (highlight to show) and I can get to 16 but not sure if I only got that because I knew the final answer.
Please help. It's driving me crazy!
