Collection of Jupyter notebooks illustrating various techniques in computational acoustics

Computational Acoustics

This repository contains a (hopefully growing) collection of Jupyter notebooks illustrating various techniques in computational acoustics. You can give the repository a Star if you like the notebooks. You are invited to contribute by reporting errors and suggestions as issues or directly via [email protected]. We are also looking forward to new examples.
