Just an FYI - RT60 is not one value as it varies across the frequency spectrum and should not be / is rarely the same throughout.

I understand. To keep it simple I used the median number.

Ron,
I tried the ipad app .. its quite nifty for a quick and dirty measure .. pretty sure its not very accurate below 100hz or so
I think this shows stored energy in my old transmission lines in elevated mids and room does need more bass traps
Waiting for new dipoles to be finished before I futz with room
I should try pink noise plot with clio and see how they compare
Cheers
Phil

I am glad you downloaded the app! It is fun to see these results!

What new dipoles are you getting?

I'm building some .. will do a thread on it when I have finished .. like most things covid slowed it down a bit

using two layers of sheetrock is excellent however they should ideally be different thickness like 5/8 and 3/4 and use a product like room damp between them gluing them together is not the right way. You can use damping sheets between instead of the room damp but I found my room quieter with the room damp, staggered studs and insulation. I am thinking of taking the wall to wall on croncrete and removing 1/3 of it so my speakers will sit on a flat and hard surface that allows the eEVPS and footers to work better and allow me to perfectly level my speakers.

I highly suggest you have the DIMS of your room run by someone like Norm Varney to help predict the outcome and who has built lots of rooms and is very experienced and helpful in making a good quiet room with no bad room nodes.

I would warn you that concrete is seldom perfectly flat if that is what you are thinking . The solid surface I believe is beneficial for my speakers, component stand and turntable in particular.

Hi all. My apologies for the delay in posting pics of my room for those who are interested. I’ve recently added some diffusers which gave the room a more spacious feel.

I agree with the quick and dirty...so many variables.

What I am wondering is are we using the same app? My results just show a numerical result for 500hz, 1000 and 2000hz. I was using my IPhone. Ron?

Not Ron.... but I think it is ipad only

I believe the back of the chair should not rise above the shoulders

My audio store had these chairs in one of their listening rooms, customers found them very comfortable. My wife liked them, so we had a couple made.

I suppose this room qualifies under the thread title as a dedicated audio room, in that it was designed for listening to music, although we often read and have a drink in here. There are two audio systems in the room, 2-channel and a spatial ceiling system for chilling.

Argh! I remember my own room at that state — I could hear the money pouring through my fingers!

Yeah....but now look at what you have.

 

[Ronboco]

Argh! I remember my own room at that state — I could hear the money pouring through my fingers!

But so worth it huh!

 

[Bobvin]

But so worth it huh!

For sure, with a great room all upgrades, changes, tweaks are more easily heard. And when you put top level kit in a great room —> sonic bliss.

Not so bad. We rebuilt most of the house except for one floor and the roof, and extended needing a foundation that took a month to construct because it had to go down 10 feet, was 40 feet long, and had to be dug mostly by hand. We had good builders, my wife did all the design, I managed it, we have an excellent cabinet-maker who we've known 30 years, we got discounts everywhere and were fortunate to do it in 2021, since when materials costs have gone up 30%.

Having finished the work and used the room for a year, I decided the tonality was a bit too analytical, so I went for a warmer sound. Involved changing the electronics, the speakers had been chosen for this room before we rebuilt.

I think I've got sensible level kit, certainly not top level. I do have a top level dealer who came round to align the speakers and he was blown away with the design of the rest of the house, which was a nice compliment for the wife. He had them done in less than an hour because he found the acoustic of the room very easy to work with.

I think it makes sense to build solid, rigid and structurally sound walls and floor and ceiling. I think natural brick and natural hardwood are good interior wall materials. But I am glad I did not build into the walls, floor and ceiling, and bake irreversibly into the cake, all of the absorption which was recommended to me by my professional acoustician.

As per the image above at ±150, that's exactly what I had to start with. Solid natural brick walls and natural hardwood floor. I was inspired by the fact that great listening spaces were created in the 18th and 19th centuries with solid brick and wood floors, in particular Holywell Music Room, which is almost 300 years old and a great venue.


Our oak floor was made from some beams from an old farmhouse in France we got about 25 years ago and cut to about 30mm thickness. The walls are lined with a product called Acoustiwall, which is very popular, and the ceiling is made of Soundbloc board. There is acoustic glass in the windows. I got advice from a specialist supplier for acoustic products called Muffle, but I did not consult an acoustic engineer.

Welcome to Muffle.co.uk! As experts in all things acoustic, we’re pleased to be able to bring you a huge range of acoustic products to buy online.

www.muffle.co.uk

There is a vast range of acoustic products that look great and don't turn your house into a recording studio. I like Baux from Sweden, but the wife wanted silk so we got silk walls and blinds.

The end result is a sound quality that is as good as I could have hoped for by being sensible rather than overly scientific.

The ceiling contains a second 6-speaker spatial sound system that fills the room, so two or more people and sit and read or chill on the chaise longe surrounded by music.

Much better acoustics than Holywell are at the Sheldonian round the corner, also built in the 1600s, but watch only the Oxford Philharmonic there as they are brilliant. In fact on Dec 15th if you are around, they are performing Schubert's 9th there and Janine Jansen will open.

That said, concert hall acoustics are fine because they have hundreds of people sitting in covering the floors and seats.

Beautiful and very tastefully designed room.

 

[ssfas]

I was going to suggest that if you want good sound, invite round your 50 closest friends and scatter them around the room. Holywell full of people is very good for 1748, only a decade after Covent Garden Mk1 and St John's Smith Square were built. My next two "ye olde" gigs are at St Martins, Sir JEG doing Handel minus Sir JEG (who is indisposed for doing what he's done for years) and the Dunedin featuring Hugh Cutting.
