I am new to matlab and i am findings ways to produce the acoustic waves in the matlab for finding the lekage detection of PVC water pipes.

I am trying to generate single acoustic sound and then i would like to build a dataset by the help of matlab.

Kindly, any one can guide me how i can do this? any references is a good start.

Thankyou.

Thank you Diyva Gaddipati.

I got that, i can produce that single data, where as i am trying to produce a audio datset for training and validating my ML model.

make_wav_file.m

We don't know what sound might help find leaks in PVC pipes. There are an infinite number of sounds that could be made. You're going to have to determine the waveform, and that's not a MATLAB question. All we can do is show you how to make a sound file in MATLAB, given the waveform, like the attached demo does.
