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") without any added notes!
Earlier exams:
Earlier exam (2009/1) solutions.
Earlier exam (2009/8) solutions.
Earlier exam (2011) solutions.
Course Literature
Primarily excerpts from: Mendel Kleiner: "Acoustics and Audio Technology, third edition", list of equations ("Useful formulae"), two lab notes, exercises and solutions.
Acoustics and Audio Technology
Audio Technology and Acoustics, third Edition, is an introductory text for students of sound and vibration as well as electrical and electronic engineering, civil and mechanical engineering, computer science, signals and systems, and engineering physics. A basic knowledge of basic engineering mathematics and physics is assumed. Problems are included at the end of the chapters. This book covers the physical background to and mathematical treatment of sound propagation, the properties of human hearing, the generation and radiation of sound as well as noise control, and the technologies used for pickup, recording, and reproduction of sound in various environments, and more.
The book by M. Kleiner "Acoustics and Audio Technology, third Edition," can be purchased at the Cremona bookstore in the student union building. The price at Cremona is SEK about 475 SEK including VAT, about 25% less than web stores.
Additional material: Exercise notes (see additional downloads)
Home Exercises
There are three compulsory exercises tasks before each exercise.
The tasks will be posted here one week before the exercise.
Be prepared to calculate the tasks on the white board. A sign up list will lay out in advance of each exercise. Everybody has to calculate at least 1 task at the whiteboard and has to have prepared at least 60 percent of the given tasks.

Lab Work
There are two compulsory labs in the course.
Those are: 1. Sound absorption measurements using a reverberation chamber, and 2. Loudspeaker measurements using an anechoic chamber. A schedule for the lab-work will be posted at the department. The lab notes contain important information and homework that must be studied prior to the labs. There will be an oral test in conjunction with the start of each lab, if your results are unsatisfactory you may be barred from attending the lab.
Lab 1 -Anechoic chamber (277kb)
Lab 2- Reverberation room (426kb)

Suggested extra material
An alternative book covering the main topics of the course is:
H.Kuttruff "Acoustics - An introduction", ISBN 978-0-415-38680-7
there are some of this book in the acoustics library.
For those of you interested in audio electronics, i.e. amplifiers and such, the following three books will be of interest:
D. Self et al. "Audio Engineering - know it all", ISBN 978-1-85617-526-5 (2009)
J.L. Hood "Audio Electronics", ISBN 0-7506-4332-3 (1999)
J.L. Hood "The Art of Linear Electronics" ISBN 0-7506-0868-4 (1993)
J. D'Appolito "Testing Loudspeakers" ISBN 1-88280-17-6 (1998)
This book is of historical interest:
J. Moir "High Quality Sound Reproduction", Chapman & Hall (1961)
If you are interested in doing your own listening tests, you should first study the book by Bech & Zacharov "Perceptual Audio Evaluation - Theory, Method and Application" (2006) ISBN-13: 978-0470869239.
Excellent material on audio measurements is available at http://ap.com/download/books and at http://en.wikipedia.org/wiki/Audio_system_measurements.
You will also find much material on audio and audio electronics at www.aes.org, which is the website of the Audio Engineering Society (AES). Look particularly at their collections of papers from the biannual AES conventions and at the Journal of the Audio Engineering Society.
Correspondingly you will find information on most aspects of acoustics at asa.aip.org which is the website of the Acoustical Society of America (ASA). The society publishes the Journal of the Acoustical Society of America (JASA) as well as a web based "journal".
