5 Essential Tips on Room Acoustics

Dealing with the acoustics of a room is just as important as selecting studio monitors or setting up your computer to work on music production. Ignoring room acoustics will result in poor speaker performance and sound perception. This will happen regardless of the quality of your gear. Investing in high-quality isolation materials may not be as appealing as selecting other, more inspiring pieces of studio equipment. However, it will mean so much in aspects of sonic enhancements. In our next article, we'll review some vital tips on this topic.

Begin With the Basics of Acoustics

To begin with, strive for a larger space for a control room rather than a small one. It can be a converted garage, basement room, or another room. You may research a good room ratio on the internet. One essential point to consider is to avoid rooms that are precisely square or have a length-to-width ratio of 1:1.5. Surprisingly, ratios of 1:1.4 and 1:1.6 are excellent, while 1:1.5 is not. If you have the luxury of designing the space from the ground up, you should employ appropriate ratios in all three dimensions. This is especially important to improve the space's low-frequency response.

Approach Measurement of Acoustics With Care

When measuring and analyzing room sound, cutting corners or taking a do-it-yourself approach is often counterproductive. If you're willing to put in all the effort of measuring your room's response, try to do what it takes to get a professional result. There are many measurement software and equipment alternatives you can search and compare on the internet.

Placement of the Studio Monitors

The listener's ears should be equally distant from the monitors. With monitors inclined 30 degrees towards the listener, an equilateral listening triangle should be formed. The triangle tip should be around 18 inches behind the engineer's ears. Positioning the monitors directly against the wall will boost low-frequency output in a reasonably consistent way. Placing the monitors away from the wall results in a low-frequency null that varies with distance. The null may be pretty deep—more than 20 dB—so it must be carefully considered. In a few words, there are a lot of mathematics and sound practices regarding studio monitor placement. It's also worth some research.

Consider Treating Side-Wall Reflection Points

It's critical for proper stereo imaging to address reflection spots on the side walls about the engineer's sitting location. This treatment should be done using 2-inch deep fiberglass panels or something similar. If you wish to expand the region with solid and stable stereo imaging into the back of the room, you should apply treatment across the whole side wall. These reflection points are pretty easy to find. You may use a mirror in which you look from the listener's position and note where along the wall you can see the monitors.

Watch Out for Poor Quality Foams

Be wary of foam suppliers who sell low-cost acoustic foam. There's no way of knowing whether they're up to par regarding performance. Therefore, it's typically best to spend a little more with specialized companies with a proven track record. Some people still argue that old egg cartons will do a great job at absorbing reflection, but the truth is, they are not that good at all. Plus, they look terrible!
