Hi Dennis. That's a very helpful analogy. I have one of those problem rooms. 20x20x7.5' high. After roughly calculating the modes, reverb, etc., the amount of remediation needed far exceeds my pay-grade, and is daunting enough I've had to re-think. Is building out the room worth it? It's only a hobby studio live room setup for making vanity-albums, not concerned with radio-ready quality. Most concern is the mixing. Perhaps I'll start small. Build a couple of BDA units from the diy plans I purchased a few years ago. Put a small leak in the dam, and chisel away one unit at a time. Or thinking like, drop a BDA into glass, and it sponges up some water. Keep dropping in remediation until the glass is dry. Thanks Dennis. For me this helped a lot in finding a place to start.

Find another ceiling height.

Nice illustration. I often use a carnival mirror as an example. A curvy mirror distorts the image. When the mirror is perfectly flat and clean, the image is no longer distorted. The more we can treat the sound issues (Reverb etc.), the flatter we get that "Mirror" getting an accurate representation of the audio that we desire. Future video request: Talk about live sound venues with stage monitors facing different direction from the main speakers, and generally placed on the floor and treatment of this type of room use. These rooms tend to get really complex as the main system interacts with the stage, and can even overwhelm the main system in certain frequencies.

Great topic but not for our audience. I want to stay focused on small room acoustics first and foremost. People are confused enough, unfortunately, to add another log to the fire.

Hey Dennis that is a great way of looking at things. I've be searching your channel and on internet in general... what would be the difference in having an absorption panel close/against the wall as opposed to having them hanging on a stand closer to the listening position, and say 3 feet away from left and right wall?

[@AcousticFields]

When you separate the panel from the wall, you allow for air flow on both sides of the panel thus increasing the surface area of absorption. How far away from the wall will depend on the panel type, amount, and position along with the room usage and a host of other variables to consider. Nothing is easy.

@@AcousticFields I see, I'll have to do some measurements of my own for sure. Thank you for taking time to answer!

Does this mean huge speakers are no good in smallish room ?

[@AcousticFields]

Yes, adding more energy or pressure to a room that has its issues magnified by that pressure is never welcome. Why would one want to add more to the existing problem when you are trying to solve that problem.

[@bevomcbevenstein]

I think I need to treat my 2 channel room with fire and build new.

[@AcousticFields]

That is an option and sometimes the best one.

The pessimist, the glass half empty The optimist, the glass is half full engineers: The glass is twice the size it needs to be. At least for mechanical engineers like my self 🙂

[@AcousticFields]

You must consider the sound source numbers. If its just you in the room, what are you doing? Are you singing/speaking? If its a live room with 5 individual players, then the room size/volume will react differently. Its all about frequency and amplitude when it comes to small room noise.
