wav file analysis to decibel

I want to analyze the wav file.

But I want to ask because I can't find the way I want to.

I want to bring in the wav file and make a graph so that the x-axis is time y-axis is decibel. Is there any way?

The FFT method is not what I want because the x-axis is frequency and the y-axis is decibel.

Ensure to use “audioread” function instead of “wavread” function for MATLAB version of R2019b or later.

Hope this helps!
