Room modes in acoustic design

 

Room Modes


Standing waves are a permanent fixture of all rooms, especially small rooms like the ones we use for mixing and mastering music.

Yes, they are problematic in some ways, but they can also be extremely helpful and beneficial. I'll explain.

If you are building a room from scratch, you should have calculated the best dimensions based on a good RMC. (Hint: never use the misleading online Room Mode Calculators)

Jeff Szymanski started the one I use Twenty years ago, and I have continually updated it for my personal use. You guys get the benefits by downloading it from my resources page.

Okay, so room modes are a static reality. Individually they are static but in general, they are everywhere, depending on the frequency. Let's look at them as helpers! They support the music at these positions. Let's make sure they are controlled so that we have uniform support across the audible spectrum.

When modal damping is optimal, the support is smooth throughout the room! e validate it with room measurements using a calibrated mic and software like REW. I use EASERA.

The decay targets are based on your room criteria. Much of my room criteria is IN my RMC.

Use it! Don't fight it because... Resistance is Futile. 😁 You can even build the BORG desk! 😂

The trick is having the right dimensions where the Modal Distribution is spread evenly and the room passes the Bonello Distribution Criteria.

Use software and a calibrated mic like the UMIK-1 (from minidsp) with Room EQ Wizard. Measure the empty room. Measure from various positions. Check the RMC and see if it aligns with the calculated response.

This will give you a foundation to start from.

AIR GAP BEHIND ABSORPTION PANELS

  I don't know why people misunderstand this. Perhaps it is me and my replies to specific questions. (If the teacher is good, even children will understand.) - I owe you an apology. What's with the 1" (25 mm) gap? The gap I'm talking about HERE is NOT the air gap. It is the opening through which the pressure can escape. Ex. Let's take a two-foot-square porous absorber: it is mounted either directly on the wall or ceiling, or spaced away from the wall or ceiling by a maximum of 1 inch. Up to this spacing, the pressure is allowed to build up and compress against the wall or ceiling at the frequencies relative to this absorber. This will shift the knee of the high-pass part of the absorption slightly lower in frequency. This is the part that is probably misunderstood. Again, I apologize. Here, I am only talking about the open gap that can allow pressure to escape. Now, let's get into the actual air space behind absorption: Let's use the same 2 ft by 2 ft treat...

Soundproofing

  You have figured out the ideal space for your studio. You want to get started as soon as possible to build your dream. You have worked for a long time on your plan based on your needs and desires and your workflow. What about the area around or near your space? Neighbors? You want to be able to create. You need focus and peace and quiet. Nature is not considerate of your peace and quiet. Rain, thunderstorms, dogs barking, etc. Civilization encroaches with lawnmowers, leaf blowers, muscle cars, and hot-rod motorcycles, - not mention garbage and delivery trucks. You need at least enough soundproofing to prevent these noise sources from interrupting the creative process. You must consider what the sound of your rock band may be doing to your neighbors. It is also important to consider that the criminal element, who may be tipped off to the location of your valuables – mics, equipment, speakers, etc. It is important to keep it quiet both ways. Do NOT overlook the importance of adequa...
