Diy room treatment

[QuestForThe13thNote]

Sometimes I think it goes a bit too far in hi Fi. It looks ridiculous doing all this stuff and there is still a question as to need in the original question and what measurements show.

Sometimes I think it goes a bit too far in hi Fi. It looks ridiculous doing all this stuff and there is still a question as to need in the original question and what measurements show.

Clap your hands in a sparsely furnished room with a wooden floor and then do the same in a carpeted room full of soft furniture. You don’t need a microphone and PC to tell you that your handclap sounds different in each room, but you do need those things if you want to know what frequencies are making the rooms sound different from one another so that you can attempt to flatten them out.

As for it looking ridiculous I agree that acoustic treatment can look at odds in a domestic living room, but if your hifi is in a spare bedroom or dedicated listening room then it’s game on I say.

Your room will effect your hifi sound of that there is no doubt. Is the point you are making that such effects, however bad they look on a graph, are not necessarily audible and shouldn’t be worried about too much?

Thanks Andrew. Long way to go. In fact this thread motivates me to improve more. I've already tried a couple of things which yield sonic improvements now all that's left is to measure before I decide on next steps.

It will be interesting to see what the measurements say if you’ve been doing this by ear so far. Totally flat isn’t supposed to sound very good according to the experts, and most Including myself tend to agree. I bet you’ve got a hump between 20Hz and 400Hz...

No, Gazzip sorry. I've not been doing it by ear before. All measured. Only hump is in 40-67Hz. With a nil at around 160Hz. Slightly over damped around 500Hz also as I'm mostly using tuned panels from a recording studio where speech was recorded.

What I meant was I did take a couple of panels out last night to see if I can increase the reverberation and it actually improved the sound. The biggest difference is around vocals where reverb on is more natural. 2 panels less but substantial differences. Something I've been looking to "fix" with DSP unsuccessfully since I've bought these speakers.

My Rt60 times were low before as I'm only using absorption. I thought about adding diffusion but didn't feel the need to. Sometimes it's good to have a friendly push.

I’d think probably very few people do this, and if they choose a floor type they’ve done it for looks not their hi Fi. Also very few people have the luxury of listening rooms.

The point I’m making is the effects are volume related, so the graph doesn’t indicate that or what effects of any given room. There are also too many variables that determine these effects to reliably predict to someone that treatment or not should or should not make a positive difference that is value for money, as a basis for recommending they do it and buy microphones etc, particularly when they may not have concerns. To start saying they will hear this difference on this measurement or that someone says they get this hump is somewhat difficult to envisage without being there and having an opinion, if it sounds ok. It may be that what one dislikes as bad room effects, another likes. It’s a total headf—k

Well in which case there is no point in recommending anything in this hobby.

Just threw bunch of towells over the headphones rack in the corner and I get a bit less boom from that side. Doesn't look fancy though.

I doubt there is a B&Q near you but there must me some similar places and a comparable product somewhere near you.

You will be astonished how effective they can be .*good*

I tried a roll of roofing material (rockwool) and to my surprise it didn't change anything audibly. I still have it in the shack. *unknw*

I used 6 beach towels now and I can hear some of the bass reduction.

did you take the plastic of the roll because you can get early room reflection from the wrapper Vladimir *smile*

You cheeky troll. I removed the wrapper but placed them in plastic mesh sacks so they don't roll open or flake. I don't think it affected the results, surely. *scratch_one-s_head*

lol messing with you I did put a serous link to make some cheap panels using towels which I think is a good idea .

Haha, clicked the link and it started to play from the middle of the video. Yes, I have watched it very good.

I think they suck moisture from the air and might get moldy. Will keep them for few days and see how they do.

I'm 20 mins in and its all about not bothering the neighbors, which us in detached houses don't have issues with. Any info about room acoustics in it?

 

[Vladimir]

No ****, Bobby.

yes you might want skip a bit to get to the part about room acoustics as he does drag on a little

The hair on our heads makes the most difference to sound , followed by the room.

Before iam taken lightly let me explain. I keep a shaved head. So the lack of insulation for the brain is compensated with heavy wax build up in the ears to give thermal insulation. So much that after I came back from my sail, and got my ears cleaned. The music sounded so good.

Next is the room of course. In my room everything sounds the same to me. Any mix of speakers, Amps, DAC's and cables. So getting the room out of the equation is most critical to hear what a component can do.

Though sadly I can't put in any acoustic treatment in my dining room , the least I can do is try minidsp / Dirac.

Hi guy's with all the recent interest in acoustic room treatment and dsp .I reckon it might deserve a thread on its own...

Any diy enthusiastic people could post what's and how's of such undertakings.

Also how to measure you're room and what to do about it and where to do it within a particular room would all be very helpful to the uninitiated.

I have noticed at my place of work...we have quite a few tatra ceiling tiles lying around unused and some water damaged...I'm just thinking would they make a good Base ingredient for an acoustic wall panel....I wouldn't mind trying my hand at making some diy efforts.

The usual stuff seems to be owens corning fibreglass panels which so far I can only find at gikacoustics which is based in the states,making it a bit expensive for mail order.so just thought if this ceiling tile stuff could do a job if I make it up in a stud type frame with some acoustic fabric tightly fitted etc.

Although I'm not even sure if I have any acoustic issues in my room ...but it seems every room has issues....I thought I'd might as well give it a try if it's cheap enough to do yourself....even though the wife hasn't been consulted as yet but I'm sure I can make it pretty.lol

Tatra Ceiling Tiles:

• Potential: Tatra ceiling tiles can potentially be used as a base for DIY Acoustic Wall Panels. They likely have some sound-absorbing properties.
• Considerations:
  • Density: Determine the density of the tiles. Higher density generally means better sound absorption.
  • Framing: Building a sturdy frame (e.g., with wood studs) is crucial to support the tiles and provide rigidity.
  • Covering: Covering the framed tiles with acoustic fabric is essential. This will improve aesthetics and enhance sound absorption.
  • Testing: Conduct simple tests to evaluate the sound-absorbing properties of your DIY panels.
