New 2 channel / lounge room

Hi Dennis
Lots of great info on your site thanks for your time and effort. We are going to be building a new house and I would like a good listening room
, but also be a lounge with very little use though. Speakers will be Tannoy se westminsters 15 inch , possibly at subs later thinking rel no.25 but I will see how the westminsters sound first. Size of the room is approx. ( still to be decided ) 5.00m w x 7.5 m l x 3.3 m h . Construction will be concrete floor . Would like to use timber floor rather than carpet ? . I will be using timber framing ( I see from your writings that you are not a fan of it ) , looking at 190 mm a 45 mm studs but with a 75 mm lightweight concrete exterior panels ( trade name Hebel ) to line the walls and ceiling ? We would like the room to look more like a lounge than a dedicated music room , so movable panels are one way or need to come up with other ideas . Acoustic treatment to walls and ceiling just seem to overtake ,there seem to be no products that blend in , the room should be simple not busy. Sorry for the loaded question but any help / different ideas in any area would be great.
cheers Lance from New Zealand

Hi Lance, You are asking for a full design of your room. This service is a fee-based service. Here is service and costs:
Our room design services are broken down into two parts: noise and treatment. Each has an associated fee of 1,500 USD. If you require both noise and treatment services, the fee is 2,500.00. A 50 % of design fee will be credited towards technology purchases from Acoustic Fields.
TREATMENT
The treatment design includes room size and volume, source (speaker)/listening positions within room size and volume for 2 – 40 channels, all low, middle, and high-frequency absorption management, including proper rates and levels of absorption to match usage, type/amount/position. All middle and high-frequency diffusion specified as to type/amount/position to include proper diffusion frequency response/usage. All DIY drawings are provided for all specified treatments and types. Telephone consultation is available to assist you with any build or product implementation.
NOISE
Noise analysis includes all internal/ external noise frequency and amplitude measurements taken by the client under my assistance. Noise measurements are taken inside and outside of the subject room twice a day over 7 days. Barrier design based on these seven-day noise study showing frequency, amplitude, and SPL. DIY drawings provided for barrier design are based on these measurement numbers. Material list provided to build the specified barrier. Telephone consultation is available to assist you with any build or product implementation.

Hi Dennis
Thanks for the reply. We are still a year away from building , but have just purchased a section . Will be in touch about the design ( I am an architectural designer so will try to make things work ) . My wife asks have you any pictures of rooms that look like a lounge more so than a studio with treatment , as she is not keen on the look . As to your products not sure what to do there as the cost of shipping and customs fee will be high .
cheers Lance

L, We ship to New Zealand all the time. Shipping costs are reasonable due to our volume.

Hi Dennis
Sounds good , one last question to help me with my house design . I was going to use timber frame , but reading your info I see the reason why not to use it . Can I use a light weight panel ie Hebel 75 mm thick on a timber frame to give a solid wall . My reason for not wanting to use solid concrete is because of earthquakes here and cost , when you have 2 different weight masses moving at different rates it can destroy things easy.

L, Timber frame is good to use. An ideal blend is a wood frame treatment “shell” with a poured concrete barrier shell. Rooms move with the amount and frequency of energy within them. Knowing this, a good designer will allow for this to occur. A wood framed treatment would work well to displace vibrational energy before it gets to the concrete. This allows for homeostasis to occur quickly. The goal is to let the energy move the room but get the room to back to normal (homeostasis) as quickly as possible. Thus, you avoid larger vibration signatures which with larger surface areas can reach audibility thresholds. My best build was 3 poured concrete walls 8″ thick, each on separate foundations, 6″ apart with a 3″ x 14″ timber frame for floor, walls, and ceiling room surfaces. Resting dB measurements were taken at 10 – midnight showed 24 – 27 dB SPL. You could feel the blood pumping in your ears.

Hi Dennis
Just a thought , have you used cross laminated timber walls , like a tilt panel .

Hi Dennis
https://www.xlam.co.nz/xlam-clt.html X laminated is used world wide , you can make floor , walls and ceiling .

Hi Dennis
Just a few questions on your CAW system
– What would be the minimum size room for this system
– is your CAW inside a built room or are the walls structural
-can I use drywall on the inside to look like a lounge
– can I use a concrete floor instead of the CAW as a floor
Just trying to find out what size I room including the walls I need to allow

L, You need to manage the low-frequency energy within your room and not create too small of distances for the mids and highs. A minimum width would be 14′. You will then lose 2′ total width, 1′ on each side wall. This would make your net width at 12′. This is a minimum width for any audio usage. Walls are framed with 2″ x 12″ studs so yes these can be load bearing. The additional weight of the carbon filters is not an issue and actually adds to the rooms rigidity. You can use a concrete floor. If your room size/volume/usage are not compatible, you may have to frame the floor with 2′ x 12″ studs. Ceiling heights need to start at 11′. Do not use drywall as a surface layer inside any audio room.

Hi Dennis
Hopefully coming to see you about a room design in a new house , but have the chance to buy a pair of subwoofers rel no.25 for music only . My speakers are Tannoy Wesminsters se . Room size will be 6.7 m long 6.4 m wide 3.66 m high with ( hopefully ) your 12 x 2 stud wall system with carbon box infills etc. My question is will the sub’s offer better sound ( seems to be more people using sub’s in music systems ) or am I better without them .
cheers Lance Dixon
