##### Course Literature

The literature will be provided in electronic form and is reference on the very last slide of each deck. Note that you will need a Chalmers IP to access it.

The literature is composed of excerpts from the following text books:

- M. Kleiner, “Acoustics and Audio Technology,” J. Ross Publishing, 2017

(accessible for online reading here and here) - H. Kuttruff, “Acoustics – An introduction“, CRC Press, 2006
- M. Möser, “Engineering Acoustics,” 2nd edition, Springer, 2009
- S. Garret, “Understanding Acoustics,” Springer, 2017

And the following lecture notes:

- Lecture notes on audio technology by Per Sjösten

We also use list of equations (“Useful formulae”), lecture notes, exercises and solutions provided on this website.
