How to determine the energy at different frequency bands of an acoustic signal?

22 views (last 30 days)
Please, I have an acoustic signal and I have been able to convert it the frequency domain using FFT. Now I would like to determine the the energy of different frequency bands (A-weighting function) as a function of the energy of the entire frequency spectrum.
Please, I would like to know how this could be done in Matlab.
Thank you.

Hii,
You can use "weightingFilter" function to apply A-weighting filter to input singal and use "bandpower" function to caluclate power in a particular frequency interval.By dividing the power in a particualr frequency by total power gives us the percentage of total power.
