I am not well versed in acoustics so bear with me......
I am reading a report that presents an acoustic noise chart whereby a range of 1/3 octave sound pressure vs a frequency range is plotted. The report states a "worst case" value (dB) at a specific frequency and goes on to say that this can be converted to an equivalent 3-sigma pressure. I am familiar with using Miner's rule to convert to an equivalent 3-sigma peak load factor (G's) using a PSD curve, natural frequency and structural gain, but not familiar with converting acoustical noise into a pressure. Can someone explain this to me?
v/r,
