Acoustic Treatment and Design for Recording Studios and Listening Rooms by Ethan Winer This page was last updated on June 26, 2011. Hungarian readers, see THIS version that was kindly translated by Tamás Bánfi.
A crash course in acoustics in Modes. This is by no means complete, but it should serve as a good starting point for someone looking to learn about acoustics. Great for someone building a home or professional studio, or looking to correct problems for their home theater system.
We generally think of the speakers in our stereo or home theater systems as the final link in the audio chain — and the one that makes the biggest difference to our ears. But there's much more to the sound we hear than just where you place your speakers in a stereo or home theater setup , and what comes out of them. You might not even realize it, but your room plays a rather large part in the sound that you hear from your system. And as with any other component, there are steps you can take to improve your room's performance. Why your room matters The sound that you hear in any room is a combination of the direct sound that travels straight from your speakers to your ears, and the indirect reflected sound — the sound from your speakers that bounces off the walls, floor, ceiling, and furniture before it reaches your ears.
[ edit ] Introduction Many people use one or two rooms in their living space as "theatrical" rooms where theater or music room activities commence. It is a common misconception that adding speakers to the room will enhance the quality of the room acoustics. There are other simple things that can be done to increase the room's acoustics to produce sound that is similar to "theater" sound. This site will take you through some simple background knowledge on acoustics and then explain some solutions that will help improve sound quality in a room.
Step-by-step instructions to set up the speakers After so much theory we are pleased to give you a practical example. These are the basic rules to create perfect listening conditions. Even your friends and family can share the acoustic pleasure, and they will feel like they are sitting in the 20th row of the concert hall instead of sitting in the 10th row, which is usually preferred by opera directors and music critics. Once you have homed in on the right place, you should start to fine-tune the position of the loudspeakers. If you angle the speakers, you will roughly influence the balance of high frequencies (due to the directivity characteristic) and the spatial bass performance at the outer edges of the soundstage (due to the influence of inevitable reflections at the cabinet corner of the speaker).
