5. Calculate the pressure amplitudes for SPL readings of 26dB and 20dB. How are the two pressure amplitudes related?
dB = 20log (input/ref)
Part 1:
26 / 20 = 1.3
log(ref) = -4.698970
1.3 + -4.698970 = -3.39897
10^-3.39897 = 3.990524
3.990524 N/m^2 which is basically 4 N/m^2
which doesn't make any sense at all because 56dB came out as less Newtons per
