RealTraps partner Ethan Winer is well known throughout the audio industry for the dozens of technical articles he has written over the years. The following articles are those that relate to acoustics and acoustic treatment which we believe will be of interest to all recording engineers and audiophiles. Most of these articles were previously published in audio magazines, but several are the result of original research and testing done at the RealTraps laboratory.
If you'd rather not spend a lot of time reading up on acoustics, we have many Videos you can just sit back and watch. And if even that is too much effort, we're glad to tell you exactly what you need and where to put it as part of the purchase of our products.
|Acoustics Basics explains the basics of acoustic treatment and bass traps. After you read this article you'll know exactly what's needed to treat almost any room! Top|

The article Rear Wall Treatment Strategies explains this in detail, and offers several options at different price points.|
|Conventional wisdom says that true reverberation can't exist in small rooms, yet many famous recording studios use small rooms for their live reverb chambers. In his article Can small rooms have reverb? RealTraps co-owner Ethan Winer explains the science.|
|Most rooms have three pairs of parallel surfaces, so it can be difficult to identify which is the cause of prominent flutter echo. To solve this, our Flutter to Distance chart shows the relation between musical pitches and physical distance.|
|Even very small rooms can sound excellent given enough bass traps and other treatment. The Manhattan Home Theater shows a treatment strategy that will transform even a tiny Manhattan bedroom into a listening room that sounds simply amazing.|
|In his third article, Characteristics of a Good-Sounding Room, Jim Lindenschmidt explains there's no such thing as a perfect-sounding room. Further, no matter how good a room might sound on its own, every room can be improved with intelligently-applied acoustic treatment.|
|In his article, Acoustic Design for the Project Studio, Jim Lindenschmidt expounds further on the importance of room acoustics and treatment for project studios.|
|The conventional wisdom is that wood surfaces impart a "warm" sound to a room, compared to cement, linoleum, or drywall. But is this really true? Find out for yourself in our article Does Wood Really Sound Warm?|
|People often ask which affordable microphones I recommend for measuring their room. To answer this question I tested ten popular microphones ranging from an inexpensive DIY model to a Josephson with Microtech Gefell capsule costing $1,800. The results are in this Microphone Comparison article. Top|
|Sound on Sound is an excellent British audio magazine, and this Sounding Off column explains why having proper acoustic treatment is far more important than what gear you own.|
magazine asked me to write this Room Acoustics article for their
theme issue The Vibe Studio. It explains the most common acoustic problems, and
lists the top ten things you can do to
improve the sound in your room.
Improve Your Monitoring is also from EQ magazine, popular with recording engineers, but it's equally relevant for audiophiles and home theater enthusiasts.
I wrote Recording Spaces for EQ magazine to explain the acoustic issues unique to recording and mixing in small rooms. In particular, this article describes the problem with comb filtering that occurs near room boundaries.
My EQ magazine article How to Tune Your Room explains the basic steps needed to achieve acoustic nirvana.
|In Measuring Absorption you'll learn how acoustic absorbers are measured, and why published test values can be unreliable and are often inflated.|
|How Does That Sound Look? was written by guest author Dan FitzGerald as a beginner's guide to understanding room measurements.|
|The Audibility of Narrow-Band EQ dispels the common myth that narrow EQ boosts and cuts - and by extension narrow acoustic peaks and nulls - are not audible. Top|
|Alternative Test Methods for Acoustic Treatment Products explains the problems with conventional absorber testing in more technical terms than Measuring Absorption above. This newer article is from Sound & Vibration, a magazine written by and for professional acousticians.|
|Many audiophiles and home theater owners treat the entire front portion of their room with absorption. But is that much absorption really necessary? Learn the facts in our exclusive feature Front Wall Absorption. Top|

|Rives Audio asked us to write this Bass Traps article for their series on the importance of acoustics and acoustic treatment. Rives Audio is a good friend of ours, and they design first-rate listening rooms and home theaters. Click the logo at left to visit their web site. Top|
|In A New Approach to Small Room Acoustics from Electronic Musician magazine I explain why the conventional wisdom for room measurement and treatment no longer applies for the ever-smaller rooms people are using to record and mix music.|
|The article Bass Waves in the Control Room from Tape Op magazine was written by noted studio designer Wes Lachot. It's included here because it explains an extremely important acoustic principle that eludes a lot of people, including many degreed acousticians! Top|
|Some people believe that equalizers or digital signal processing (DSP) can reduce the need for bass traps. While it's true that EQ can reduce the volume of peaks, it can't improve nulls or reduce ringing which are just as damaging. To prove this we measured the Audyssey MultEQ "room correction" hardware system. Note that newer software products make similar claims, but they're subject to the same limitations.|
|Do Room Modes Even Matter? Yes, but probably not as much as many acousticians would have you believe.|
|I wrote Audio's Dirty Little Secret for Pro Sound News to explain a surprisingly common problem that many audio engineers do not even know exists! Top|
|Acoustics Facts & Fiction explains the basics of acoustic treatment and bass traps in plain English with no math or technical jargon. There's also a link to a terrific software signal generator you can download for free to play sine waves, pink noise, and other test signals through your system. Top|
