Anyone got experience with acoustic panels?

I'm liaising with Joe at blue frog audio, nice guy. Going to get some panels from him just wondered if anyone has experience of treating their lounge/theatre space?

If so what was your approach?
I have done a lot of reading so already aware of 'treat bass with corner traps' (can't no room) and 'treat first reflections'.

Cheers
 
I have a couple of GIK bass traps that I've put in the corners behind my main speakers.
Be aware that most rooms will have a room "node" where you'll get a significant bass "peak". In my lounge, it's at 38hz, with a secondary at 76hz. A bass trap will NOT get rid of that peak. The only effective method I've found is electronic DSP and deliberately tuning out that peak.
I did however find that the bass traps did help clean up the low end and reduce the diffusion of sound around the room. So yes, IMO, they were worth the cost, at least in the context of my system.

A few years ago, I also met a acoustic engineer, who'd done his whole lounge. By done, I mean that he'd replaced all of the standard walls panels with acoustic absorbent versions, backed with some acoustic foam. It was clearly a big job, but as it was what he did, he was more than capable. Have to say, his room sounded great.
 
Thanks, forgot to mention I do have dual subs with an antinode so bass response as actually really pleasant and broad in the room.
 
Hi there

I built 5 of my own acoustic panels recently with 5 layers of cotton towels per panel. Main purpose was to clean up reflections and reduce the sting in the room from echo, and they did the job superbly.

I was very happy with results, and then proceeded to setup my Anthem MRX with some room correction. Sounded fantastic :-)

Buys anthem mrx but too cheap to buy £30 roll of rockwool

2nd hand MRX 310 @ £300, and being an engineer I was interested as to whether I could build my own and how effective they would be at absorbing sound clever clogs ;)

Sourced all of my towels from charity shops too

Probably thought I was a right weirdo :cool:
 
This is quite interesting as I'm currently studying physics at the ou. I say interesting as I've just read about the waves we hear, my concern would be if you get rid of all the echoes, won't you have an issue where certain frequencies will be nodes whereas some will be antinodes at the mlp, which cannot be corrected out?

Yeah absolutely, hence why you don’t fill your room with them. Furthermore, the acoustic panels won’t be able to absorb 100% of the sound - they’re not dense enough and they’re entirely flat (practically speaking).

The purpose of these is to help combat unwanted, additional sound. You don’t want the room to sound dead - you still want to hear the characteristics of it without as many echos :)

It’s very complex, and one could spend an age on the subject, but the fact of the matter is that a few panels will almost always improve the sound in a room, if placed strategically.
 
Mmm, was thinking of these myself in a new cinema room, however got a sound calibrator coming in 30th November when build is complete so hopefully he can recommend what and where I would need anything.

Sounds cool be interested to hear what is recommended.
 
I have some panels from Blue Frog to treat my first reflection points. It made an enormous positive difference to the stereo image for music, and accuracy of the front and centre channel for A/V.

Well worth doing, but make sure you take measurements and research to do it right.

Yeah exactly I have a guy coming over when the build is complete on 30th November, I'm expecting all sorts of sound problems, as it's a new build, but that's why i want him, to setup as good as he can now and also to highlight any problems and what I can do with them. We shall see... he's doing both my PJ and my sound system so fingers crossed...
