One for the future for me
I've done little since moving into this room apart from adding thin curtains
I'll start simple and work on from there when I have the kit settled
Room position is the one I'm working on right now

Good article. There is a lot you can do by experimentation and 'suck it and see' trials. Even opening & closing the curtains should make a difference. Don't be put off from a little experimentation.

I like this "...much can be deduced about a room's mid-range performance simply by holding a conversation in it..." and totally agree. In fact, standing in the middle of your listening room and talking in a normal voice tells you lots. Now try the same experiment in the kitchen and in a bedroom. Hear the difference? If so, you can start making changes and use your own ears as tools for the job.

Is there anyone here capable pf presi'ing the article. I can't read anything so wordy. I don't mean this to criticise. It is a genuin call for help, as the concept is of great interest.

Do you want someone to summarise key points

Yes. What happens on forums is some people cop out of creating a discussion by just sending a link to a great long discourse which was held somewhere else. a place where there would already have been an understanding among the group and knowledge of the nuances of the way the poster writes.
I believe that it is better protocol in a place where the background information isn't present, to introduce the topic at a pace that a total neby can appreciate the progression and learn.
A topic which develops naturally like this can be a magnet to a forum.
a place with links to great long in depth threads nobody has the time to start reading will not grow cohesively into an entity of itself.
My problem is dyslexia. I don't read instructions I learn by touch and feal. But out of interest my mental abilities as a dyslexically wired person like Einstein mean that by my touchy feely method of learning I am an extremely competent boiler repair man. I can also be very inovative in valve amplifier design.
but I never go and get absorbed in a long wordy link anyone posts out of context.

No worries I have Dyspraxia so suffer with similar issues

Yes. Are you tall by any chance? I am not.
I was a nurse until 2003 and I attended a very high brow seminar in a room full of consultants from all around the nation on dyspraxia.
much more prevalent in boys than girls and very common in tall fast growing boys. these same also suffer collapsed lung while they are growing. But after they are fully grown no reason why collapsed lung should persist.
Dam, I have opened the door to an autistic person to say I am off topic.

For Paul
What the article suggest is not to overdo room treatments I think to a degree we want a bit of aliveness and do not want all the energy and the soul of the music drained from it. What it suggests is the room functions as energy store and returning that energy this gives a degree of reverb in the room. Some reverb is good but to much reverb is not. The next issue is room modes, this could be seen a peaks in frequency. This can have a dramatic influence on sound
I post some more from the next few articles latter on

Correct. Audio enthusiasts tend to assume that acoustic absorption is required in listening rooms; and, up to a point, that's correct. But, listening rooms (in the UK at least) tend to be small and small rooms cannot accommodate very much absorption before becoming too 'dead'. Try having a conversation in an anechoic chamber and it's not nice. The key in a listening room is to have enough absorption to control excess reverberation and maybe flutter echoes, but in truth most people have enough soft furnishings and floor coverings to achieve this without adding much else. Where enthusiasts really go wrong is in confusing absorption with diffusion. Diffusive elements (eg bookcases, record racks or commercial diffusion panels) can really bring a room to life, often when used in places where 'conventional wisdom' says absorption should be used. So, a diffusive panel (which can be an attractive thing) placed between the speakers and behind the listener can work wonders. I rather like the diffusive panels made by Kaiser Akustik, but God only knows what they cost! ![]() Also, most enthusiasts do not understand that room modes are a natural function of the room and cannot be eliminated. You can play around with input energy and with things like bass traps, but actually moving the speakers or listening position will have greater effect at no cost - the modes will always be there. If anyone does not believe this, I recommend a visit to a Reverberation Chamber, where the modes can be heard and felt as you walk around. There's no substitute for feeling and visualising what's going on. Place your head in a peak or null and the system will clearly sound wrong, but you only have to move the listening position by a small degree to achieve a better sound balance. |

That balance thing. I first discovered 'balance' when learning about litho printing - you need a balance or ink and water or it don't work. What a pain I thought. I tried my hand at litho printing with a poor teacher and I was rubbish.4 Like so much it's dead easy when you know what you are doing. Since then I discovered balance is there in (almost ?) everything. Too much of a good thing is a bad thing  |

As well as Acoustic Sciences, another good vendor of absorption/diffusion products are GIK, who are cheaper and based in the UK for those of us who live there and want to reduce shipping charges. |

The panel I had made to cover my TV was from GIK, finished in my own selected image (the other panels behind the speakers are from Acoustic Sciences).

That looks fantastic Martin, so much better than looking at a black rectangle in the middle.
We are luck in that the 40 inch TV just fits into the centre section of the somewhat large cabinet, with nice oak doors to hide it when not in use.
Cheers, Alan

Yes, but it's the only one I have of the TV panel. ...and anyone knows that black is old hat and silver is the real deal  |

Yep, silver is the new black. ☺
