So Much for 'The Perfect Room'...... I've considered multiple layers of sheet rock but not on ALL walls. On adjaceent walls, yes, but only 2 of the 4 main walls. Celling needs another idea. Non-Parallel walls? Maybe that would help. And staggered studs so the 2 sides of an interio wall were not BOTH secured to opposite sides of the SAME stud.... That would make it a drum head. Trouble? Well, Yes. Lots of interesting things can be done for NEW construction. But in a renovation or simply making a listening room? Options close down.... "Drum head" is good, actually ... best for the walls and floor and ceiling to flex. That absorbs low frequency energy, and will not re-radiate it into the room or anything bad like that. I made my room too stiff, and if I did it over I'd use the thinnest panels I could find and not attach them to studs except top and bottom. What works to prevent transmission (soundproofing) can work against what you need for the room to sound good inside. Non-parallel walls work for slap-echo, i.e. mid to higher frequencies. Basically it gets back to 1/4 wavelength which also applies to resistive (fiberglass, rockwool) absorbers. For non-parallel walls to have an effect at 100Hz, they would have to be angled nearly 3ft. To affect 50Hz, it would be 6ft. So for low frequencies it's not practical. I read a study where it was confirmed though, and with very large angles low frequency resonance modes don't happen. |

If you want a few tips on building a studio listening space, my old pal Ethan Winer has an interesting web site (and he sells acoustic treatments so the info is slanted toward his products, but the concepts are universal if you look past the embedded ads.) The site is not super easy to use, sorry about that. Ethan is an old guy like me ethanwiner.com/articles.html |

He's very generous with his knowledge. I've made my own traps based on his info, and I have a couple RealTraps. Maybe my favorite is his "Null Tester" video where he tests cables. He doesn't like digital room correction, but thankfully he has said he will never again test digital room correction software.  |

The site is not super easy to use, sorry about that. Ethan is an old guy like me ethanwiner.com/articles.htmlA true studio space would be awful as a listening space. The one studio I was in was extremely 'dead'. Standing back to back with someone and holding a conversation was .....odd...... This same studio? DID have non-parallel walls. A zig-zag at a certain angle on ONE side and a different angle on the OTHER. That technique really broke up the possibility of standing waves. Ceiling was also sawtoothed and made with very thick panels. The 'garage door' end was OVER a foot thick of insulation / padding. And acoustically dead. The only live spot in the room was where the Baby Grand sat. Piano was on hard floor and a maybe 8 or 9 foot ceiling. My DAD build that operation. He had gone down to Hollywood and Talked His Way INTO a couple studios for 'the tour'. What a guy. But he also didn't miss a trick. And was a good observer. I have only touched on the build-features. Many more! |
