best room for sound

You can't just look at a picture of a room and know what it's going to sound like..

It's like looking at a bit of kit and knowing what its going to sound like..

Oh wait:)

Absolutely.

You can't know till you get in there and simulations usually fool more than inform. For example, no room is truly symmetrical, except by chance. But you've got to start somewhere, room dimensions is a pretty good place to start, and presumably Bottleneck is going to ask some more questions further down the line. :)

yeah :)

bought a laser measurer thingy (estate agents don't give ceiling measurements or window measurements).

Idea is, to get some more exact measurements and run some stuff through CARA.
 
No computer program will give you exact, even close, results, it is impossible to predict wall stiffness, etc...

But you can always get main room nodes... ;)
 
Cara models wall construction as well as door and window materials, floor make up and many other things.

Here is something interesting that I've just read:


60 Hz - 12ft 40 Hz - 16ft 30Hz - 24ft 20Hz - 32ft "

If we presume that the article is correct, this goes to show the meaninglessness of plumbing the depths with low frequencies in a small room.... or, to put it another way, your speakers may go to 30hz, but if your room isn't 24 feet long, you're never going to hear it!!

Surely this is wrongly interpreted. Most people's living rooms are not big enough if you apply this. Is it not the case that you will hear the low notes, only they will come over a bit funny if there is not the space to let the wave run it's course fully within the room before reflections , i.e. it will be distorted / overloud in places /unduly quiet in others and it will all depend depend depend where you are sitting and what low frequency you are talking about. But you will hear it.

Is that not a better way to interpret it ?
 
Hi Cloth Ears

I've had a few conversations, PM's and a small amount of reading off air.

It's not as simple (it seems) as the article I linked to - for many reasons.. including hot-spots, null areas and blah de blah blah.

Although some aspects of what the original article was trying to say contains truth.

It's too complex for me, and I suspect you need a lot of training in acoustics to really understand what's going on.

Yes. Remember that the LF energy has not disappeard, it's just interacting with the reflected energy to create unusual effects (nulls, peaks) that are location dependent.

And no amount of training in acoustics will ever tell you what's really going on!
 
- why not bring a little system (mini system even) & plug it in & listen at every house you view ?! :)
 
bottleneck,You may want to consider a home that can allow for a extension to build a dedicated room.A smaller home with the property to alter would be ideal.Consult with an architect in your area not the agent rollo
 
my house never sold, so I am still here for the time being!

oh well..

I'll try again in the summer when the gardens in bloom.
 
Sorry to hear about the house.

Lovely room but those dims are awfully close to 1x2x3 - that's bad, n'est-ce pas?

I really wouldn't get too hung up on some of that guidance re. room ratios. Just because you have potential modal "stacking" at a certain frequency due to near perfect room ratio multiples, it doesn't necessarily wreck the room. The multiple modes have to be driven efficiently for the "stacking" to manifest itself. Provided you are not placing speakers in corners, you can diminish the effect noticeable with careful speaker placement.
