Few DIY projects

One of my solutions, a combination of heating and an acoustic absorber, the ceiling absorbs frequencies above 4000-5000 Hertz.




Heating panels work in the infrared spectrum through Radiant heat.

Very interesting idea! Do you know how those heating panels behave in the acoustic spectrum? Are they acoustically transparent?

The heating panels are not acoustically transparent, they are is produced in Canada and haven't acoustic characteristics.
These plasterboard panels produced in Bulgaria have such. ?he ceiling absorbs frequencies above 4000-5000 Hertz.

It looks like some kind of wool, so I think it works perfectly fine as an acoustic dampener. Are you planning on doing measurements?

On the reverse side, there is a fiberglass veil on the panels, which also affects the acoustics. I've solved the problem with the mid frequencies and highs/ you can see on the graph/, the low frequencies remain, but for now I'm not in a hurry to deal with it, I have an idea for more furniture in the room.

That huge peak at 60Hz and then second one at 120Hz are probably the modes of the room. I can imagine they are pretty fatiguing. More furniture will help a little bit, but it might not be enough in this case. You might want to look into bass traps.

The volume levels at which I listen to music are low, rarely above 45-50 dB.
I have a few ideas for bass traps, but apart from efficiency, I have high requirements for to their design, they definitely need to be aesthetically pleasing and seamlessly blend in with my interior - a difficult task, but not impossible. Their time just hasn't come for yet.

One thing at a time, and you will get there
