Afternoon treatment with corner bass traps, first reflections bass traps and diffusers, would my room bed typically warmer than before any treatment?
I don't use a/con in my room in tropical climate Singapore

Basically that's how they work, turn sound waves into heat. Don't know is it actually noticeable to feel or measure the temperature change.
I personally wouldn't put any insulation material(thus basstraps) into my bedroom. Unless, you really wrap them into a plastic. No matter how safe they say it to be, i have personal experience. Didn't they declare asbestos as safe as possible but how it turned out to be?

Probably not much if any because even though it's also thermal insulation, just by placing them in your room, you have not changed your ventilation pattern. However, if you also "soundproof" or insulate and seal all walls, ceiling and floor, you will trap the air inside the room and without adequate ventilation and cooling, your room will heat up. It's also true that as Pasim says, the way porous absorbers work is to turn sound into heat, but there is actually comparatively very little acoustic energy that is actually transformed into heat so you probably won't notice any heating from that. If you're using mineral wool or fiberglass, these products have been around for decades and AFAIK, there are no lasting adverse health affects reported from them. If you're not sure, check the MSDS, example: kodiakroofing.com/wp-content/uploads/2019/10/Roxul-Mineral-Wool-SDS.pdfWhen working insulation, it's best to wear long sleeves and a dust mask but any contact with "nuisance dust" is only temporary. You only really need to wrap them with breathable fabric and as long as you don't "beat them with a stick" you will very likely be fine. Of course there are some individuals who are sensitive to everything on the planet, so YMMV. |

I haven't tested it but, yes, I feel that the insulation keeps the place warm. Also, it hasn't killed me yet.

When I had panels and bass traps, that were only covered with fabric, I got almost every time I spent long times in that room, little nose bleed. They emit the particles all the time, even if you don't hit them. If you hit them even gently, they emit really much. They definitely make air quality worse, so that's why I wouldn't put them in the place where I sleep...

What was the insulation you used? I used Thermafiber Safing Insulation. Even with panels uncovered, most all "dust" and particles were large and heavy enough to fall to the ground. When covered, I never noticed any "dust" getting past the covering, even when handling when I move them around. I use a few of them as gobos for recording. But I do have to admit that they are not in my bedroom. If I got a nosebleed from them, I'd certainly be cautious!
As far as heating up the room, with enough coverage, I guess that they would insulate the room enough to make a difference. My room basically is sealed from fresh air and the only "fresh" air is from the A/C in summer. I have hot water (hydronic) heat so there's no ventilation ducts so I can't remove the build up of air heated by amps and sweaty musicians except by opening up the room door and using a box fan to ventilate the room in between takes and during breaks etc. From that perspective, it's hard to say how much heating is caused by the panels but I'd estimate they are the least of my heat build-up problems.
For durian's room, can you use fans to ventilate outside air?

I'm using a fan to force circulate the air in my bedroom. Without the fan running, it can get a little warm due to the amps and preamplifier.
Guess the treatment would make just a little warmer. The running fan would help but think I would have to reposition the fan because its current location would be in front of the right corner bass traps.
I'll be using Roxul Safe n Sound

Since your fan cools the room enough without the bass traps, it will probably do fine with them. I honestly believe there is little detectible heat being generated by the absorbers absorbing sound and converting it to heat, if that is your concern. Here... I just looked this up: If you check the link and scroll down to the table, you'll see that the actual total of "Acoustic Power" by a source playing at 100 dB SPL is equivalent to 0.01 watts! That's ALL! If you play at 120dB SPL you get up to 1 Watt! BIG DEAL That's something but still hardly anything. So any heat actually generated by the bass traps and other absorbers is nil. The diffusers even less since they are basically reflecting and not absorbing. en.wikipedia.org/wiki/Sound_power#Table_of_selected_sound_sources See : 1.1 Table of selected sound sources Acoustic insulation is pretty much the same product as Thermal Insulation and Thermal Insulation's purpose is to slow down the transfer of heat (or cold) from inside to outside (or the other way around depending on the season). If you put Ice in a cooler it will eventually melt and the water will eventually rise to the temp outside the cooler. It's the same in your room if you have it sealed, BUT YOU DON'T, so it does a little but just not that much. And, don't forget, once the room is cooler than the outside (like maybe at night), the insulation will slow down the change of indoor temp to getting UP TO the outdoor temp. So yeah, insulation in your room can make it a little warmer, so just run your fan...or maybe get a second one? |

I won't have to worry much about the room getting warm |
