When I was completing my Bachelor degree in Physics, I started looking around to see whether I could find Universities offering courses in Acoustics, but with (mainly) audio applications in mind. Whilst many engineering departments might offer Environmental Acoustics programs, it is harder to find the ones about Audio Acoustics. I though it could be useful to summarize in this post the main options I found, both while I was looking around and afterwards.
This list is far from exhaustive, and mainly from my memory. It also only considers places where I was considering to move, so perhaps there are many more Universities around the world where to study Audio Acoustics.
Salford University: This is the university were I earned my Master Degree in Audio Acoustics. At the time I attended (2015) the university was offering few different programs: 2 Masters in acoustics, one audio oriented and one with a more environmental curriculum, plus two similarly oriented Bachelor degrees and, if I remember correctly, a program of Physics with Acoustics. See the course search for an up to date list. I am overall happy with the experience I had at Salford: it allowed me to meet many like-minded people, the school staff was always kind and helpful, and overall it was a smooth experience. However, I feel like the courses did not go as deep as I would have liked, especially those about DSP and transducer design. The reason why I attended this one instead of the others? Well, by the time I could think about enrolling to a program, this one only had open applications.
The Technical University of Denmark offers courses in acoustics. I was interested in the Engineering Acoustics Master course when I was choosing where to go for the Master, but applications were closed. The search tool returns few more results.
Technische Universität Berlin: I found about this one while looking at the background of few speakers at a conference (one the Linux Audio Conferences I believe) see the Audio Communication Group and this interesting page with many theses.
Stanford University: Interesting courses are offered by CCRMA. This department is extremely influential, especially in the realm of open source, Linux and culture dissemination. See Planet CCRMA, Julius Orion Smith and Romain Michon pages for few examples.
How to Find More?
Beside endless time on search engines, it is good to look at conferences and conventions on Acoustics and Audio: just track the Universities from where the speakers are from. For example, you might look at Linux Audio Conferences and AES.
