Course Description
Acoustics basicsThis course assumes that you have minimal knowledge about acoustics, and therefore starts slowly with some basic information about sound waves, how they are created and what are their characteristics. Then moves on to how the speaker is designed and some other relevant information about acoustics. This is obviously needed for a beginner, but it's also good for an intermediate student, as I'm sure he will also find new information to make matters even more clear.
Enclosure typesMost of the common enclosure types are listed, explaining their working principle, pro's and cons for each one. But, we will focus our attention for the sealed and bass reflex enclosures. These are covered with extensive details regarding their characteristics and how to design them according tothe standard alignments, or to complete custom response curves.
Modeling softwareTo model the response curve of the enclosure and to calculate the dimensions of the box, two methods will be used. You will receive an excel spreadsheet, that has all that you need to model a sealed or a bass reflex enclosure with minimal difficulty. It even has a chart to show you the modeled frequency response. It's basically a complete package for a beginner. The other method is by using a paid application. There are a lot of speaker design software solutions out there but I chose : "Subwoofer design toolbox". The main reasons are : it's cheap, simple, easy to understand and it has all the basic functions. If you are a beginner it's very important to start slow, otherwise you will get overwhelmed by complicated applications withextra features that will only confuse you.

Hi! My name is Marius and I'm from Romania.I majored in economics and computer science, and have a college and masters degree in this field. Regarding the audiophile part of me, I started to intensely study this area since several years ago. Its difficult to get a college degree in this field, since there are only a few universities around the world which have this specialization (from what I know, In Europe, there is a famous one in Denmark, and another in UK). The closest specialization would be electrical engineering, but I wanted something a bit more specific. So instead of going abroad for studies, I decided to study at home in my free time. The things I find important or interesting I write them down on my blog.Here is a list of books I have read, some of them even twice or three times :
1. Master Handbook of Acoustics by F. Alton Everest, Ken Pohlmann (McGraw Hill Professional, 2009)
2. Introduction to Sound System Design and Electro-Acoustics by Peter Swarte (DHvV Interactive Lab, 2014)
3. Audio Engineering Explained by Douglas Self (Taylor & Francis, 2012)
4. Electroacoustics by Mendel Kleiner (CRC Press, 2013)
5. The Audio Expert: Everything You Need to Know About Audio by Ethan Winer (Focal Press, 2012)
6. Electroacoustic Devices: Microphones and Loudspeakers 1st Edition by Glen Ballou (Focal Press, 2009)
