##### Noteboard

*2023-08-28* Warmly welcome to the course! As we are not so many registered students, I have moved the lectures and exercise classes to our lecture hall at Applied Acoustics (Sven Hultins gata 8a). See you there tomorrow for the first lecture starting at 13:15!

##### Exam

The date of the exam is announced in the Student Portal (NB: you have to register to take the exam. For more information, see Student Portal)

Tools you are allowed to bring to and use during the exam:

- Mathematical tables
- Electronic calculator without or cleared text memory
- List of equations “useful formulae” and “audio formulae”

(see additional downloads section) *All without any added notes!*

##### 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.
