Help with the MATLAB code to do the following: Given an audio recording of vehicles, compute Power Spectral Density, 1/3 octave band level, octave band level, A-weighted Leq, C-weighted Leq, L10 (unweighted since sample is short), L90 (unweighted since sample is short). If the measurement is made at approximately 50 ft, and that the vehicles are moving at an average of 65 mph, what is the flow rate Q?  If instead, the noise is dominated by 1-2 motorcycles, how fast are they going? Given- -The data are in counts -Calibration factor is 133 uPa/count -Sample rate is 44100Hz. -Remember that in air the dB reference is 20 uPa -Pwelch requires that the inputs are doubles

Question

Help with the MATLAB code to do the following:


Given an audio recording of vehicles, compute Power Spectral Density, 1/3 octave band level, octave band level, A-weighted Leq, C-weighted Leq, L10 (unweighted since sample is short), L90 (unweighted since sample is short). If the measurement is made at approximately 50 ft, and that the vehicles are moving at an average of 65 mph, what is the flow rate Q?  If instead, the noise is dominated by 1-2 motorcycles, how fast are they going?

Given-

-The data are in counts

-Calibration factor is 133 uPa/count

-Sample rate is 44100Hz.
-Remember that in air the dB reference is 20 uPa

-Pwelch requires that the inputs are doubles
