Recent Room Acoustics Articles

This article is about HAA certification training and it also contains some great information on home acoustics from the course which I have included in this article. You may find that even a few …

I often have people ask me some very basic overall questions about the acoustical design of a room, such as: how much will it cost, what will it look like, how much better is it going to sound? …

How can you deal with bass problems in small rooms to provide a more uniform response for each listening seat? Passive room treatments such as bass traps is one way which we discuss here.

This article should provide a good understanding of what can be expected in terms of the process of designing a listening room. There are five phases to most design projects. Some of the phases may …

This article summarizes the 3 part series discussing how the human ear perceived amplitude, phase and distortion to determine sound quality.

How sensitive is the human hearing to distortion? This article explores the audibility of distortion.

This article discusses how sensitive the human ear is to phase distortion and how it determines the listening quality we identify with.

Human Hearing from an auditory and perceptual standpoint is studied in this series of articles. Part I deals with Amplitude Sensitivity.

This is a very appropriate saying with regard to sound isolation. We are often asked questions like: "What can I do to this wall to stop the sound going through to the bedroom on the other …

Our first three courses in the CEDIA Seminars series covered proper system calibration after installation and set-up was complete, followed by two complementary courses on room acoustics. More often …

Tom Holman had a problem. As Professor of Film Sound at the University of Southern California's School of Cinema-Television, one of Tom's duties was to set-up, calibrate and acoustically equalize …

I get asked "What is the perfect media or listening room?" quite often. My response is usually something on the order of "It depends." And that's very true, it depends on a lot of things, but mostly …

Anthony Grimani's "Room Acoustics: Acoustic Treatments" class followed his course on "High Performance Home Theater Calibration" on the afternoon of my first day at CEDIA. I'm reviewing it here, as …

After a summer break, it's back to acoustics. I had intended writing on DIY and some basic room set up tips. However, that's going to wait until next month. I am just returning from the Denver …

John Dahl has been a volunteer instructor for CEDIA for the last 11 years. So it's a pretty good bet that virtually all of the CEDIA design and installation professionals who have passed through his …

The Custom Electronics Design and Installation Association (CEDIA) was founded in 1989 in recognition of the increasing complexity of integrating audio and video systems into the home environment. …

In 1979 TEAC introduced the 144 Portastudio, and the recording industry hasn't been the same since! In those days a decent limiter cost nearly $1,000 and a good spring reverb unit would set you back …

ModeCalc can help you design a new room that sounds as good as possible, or predict the low frequency behavior of an existing room. This tutorial explains the basics of room modes, and tells how to …

A listening room, defined by its dimensions, can be mapped in terms of a series of pressure peaks and nulls, in all three dimensions. This refers to the creation of standing waves (modes), and the …

This article describes the physics behind human hearing and sound waves. How the ear works and how we perceive sound is discussed.

I have heard some people claim "I just listen and walk around the room and clap my hands and I know what to do." I would say this is another "myth". What is true, is that final tuning of a room often …

Throughout this series we hope to educate and illustrate some of the fundamental points of room acoustics. This is by no means meant to be an intensive course on acoustics, which by the way, for …

"The room is the first thing we start with and the last thing we think about." This statement is so often true. It's unfortunate because the room, as we often refer to it as the "invisible component" …

This month we have another guest writer, Jeff Madison from RPG. Jeff is the senior product application consultant in RPG's Home Theater Division. He spent his first years at RPG developing its …

When the boundaries of a room accentuate bas frequencies, the listener's perception is one of a reduced midrange and soundstage. If you don't get the bass right, nothing ever comes together very …
