Room Acoustic Treatment

Postby angelface » Sat Aug 11, 2018 10:08 am

When I had my main system in the lounge I managed to negociate the following treatment

1200x600 GIK 244 Bass trap horizontal behind TV and thus between speakers
Foam in picture frame behind an oil painting behind the settee we use for watching TV

Now I have a dedicated listening room but it is much smaller. Sounded dreadful until I placed Bass trap behind my head.
Two more 1200x600 GIK 244 Bass traps were purchased and postioned behind speakers and towards centre so absorbing first reflections off back wall. This improved imaging and bass.

Latest purchase was two 600x600 GIK 244 panels that bridge rear corners. On some quieter tracks in feels if bass is a bit missing but with rock music the drums and bass guitar are really clear.

I have no treatment on ceiling but this is high compared with my distance from speakers. I have no treatment on side walls but again these are far enough away compared from my speaker distance.

Overall I am very happy with sound so far.

Can I recommend GIK seconds that appear most weeks on ebay if like me you love a bargain?

Well done. I still cannot believe how much a difference they have made to the sound. Huge upgrade. I used Alpha panels on side walls for reflection points & GIK 242 for ceiling.

I'm quite new to room treatments, I have watched over a dozen youtube videos.
How do you know if you need it?
I'm guessing it's when you can hear an over powering boom from the bass?

Also what do the panels look like inside, is it flat absorbing material inside a frame or is it some type of tunnel system with sound absorbing material that sends the bass on a journey?

Hi Madaboutlawns

before I installed GIK panels, I knew nothing about them, if you go to GIK website they have great section for learning what each panel does. Not all panels are for absorbing, look at reflection points.

With regards to your question how do you know if you need them, installing acoustic treatment will improve your sound “full stop”, if you email GIK & give your room size/position etc, they will recommend what to get. The good thing is you can start with a few panels & increase from there. What size of room do you have? & where is your listening position.

GIK might want you to analyse your room using a mic & raw software. It will give them the detail they need to advise what panels you need. I’ll lend you the mic if you want, just pay for postage. Cost me £150, so worth getting a lend from me.

Cheers

Michael

If you really want to get your head around acoustics then get the book Master Handbook of Acoustics (6th edition); heavy going.

GIK video's and tutorials are very useful. Its pretty straight forward stuff at a cursory view for what your looking for. Once you start getting into the specific problems such as the orders of reflections, etc down the rabbit hole you go. Explain the issues and give drawings or measurement readings, contact them for exactly what they need to assist; until you buy its no obligation.

I've gone down the absorption route with a mix of scatter panels (simple form of diffusion) too keep the sound livened. You can absorb anything, but you steal the energy completely if you go to far. I've gone to the nth degree and currently have 18 panels. But I've been dealing with reflection points and the issues after soundproofing a room.

Only thing I am not convinced by that GIK say is the idea of speakers against the wall if you have sound panels behind.

Hi,

Thanks for the advice and help.
Thank you starwarsmike2422 for the offer to borrow your mike and also thanks to caine for the info on the book.
I think I might start off with trying to get to grips with the book first.
I think I can see the rabbit hole, but I'll have to put it on hold for a short while.
My wife and I have just found out that we're having twins. So I'm a little tied up with things at the minute.
As we've already got 2 little ones I'm spending my free time trawling the internet looking for viano or v class to transport us all around in.
