Home theatre soundproofing and acoustics in Atlanta
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is. American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment.
- Containment
- Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
- Low frequency inside
- Corner absorption with depth, before any surface treatment.
- Reflections
- Side wall and ceiling first reflection points at the seating position.

01 / The material
What this material is and where it earns its place in Atlanta
Serious equipment in a room with no isolation plan. The complaint is almost never the speakers. It is bass leaving the room and an untreated box making the system sound worse than it is.
American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment.
Work reaching us from Atlanta is mostly production stages, edit and mix rooms, offices, schools, clinics, restaurants, home theatres.
- Light frame residential Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
- Savannah, then the road The container lands at the coast and drives in. We quote the sea leg and the road leg separately so the programme is built on real dates.
- Production rooms have no tolerance A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
- Containment Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for home theatre soundproofing are on the main product page. This page covers what that means for a project in Atlanta.
02 / The build-up
The stack, in the order it is installed
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Atlanta, packaged rooftop units and ducted forced air are standard, so noise arrives through the duct rather than through the wall. Lining the first three metres of duct and treating the return path is usually the whole job.
Floor, floating. Membrane under a resilient layer and a floating deck, so impact energy is broken before it reaches the slab.
-
Layer 2
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Atlanta, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Full height with return. Curtain taken floor to soffit with a side return and an overlap, because the gap is what leaks, not the fabric.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Atlanta, public school buildings run long corridors with hard floors and lay-in tile ceilings that were chosen for cost, not for speech. Classroom reverberation and corridor spill are the two complaints, and both respond to ceiling area rather than wall panels.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / In this market
What we see driving Atlanta briefs
- Light frame residential
Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
- Savannah, then the road
The container lands at the coast and drives in. We quote the sea leg and the road leg separately so the programme is built on real dates.
- Production rooms have no tolerance
A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
- Warehouse conversions
Big metal and concrete shells make superb volume and terrible acoustics. Rain on a metal deck and traffic outside both get in, and the inside is completely live.
- The housing stock
American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment.

Where the money goes on a Atlanta project
-
Containment
Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
- Soundproofing materials, 2100 kg per cubic metre. 2.5 mm STC 30 at 5.25 kg per sq m, 4 mm STC 34 at 8.4, 6 mm at 12.6
- Soundproof curtains, 10 to 12 mm
- Acoustic carpet and rugs, High density polyester
-
Low frequency inside
Corner absorption with depth, before any surface treatment. The container lands at the coast and drives in. We quote the sea leg and the road leg separately so the programme is built on real dates.
- Soundproofing materials, 1800 x 900 x 20 mm, 100 kg per cubic metre, NRC 0.85
- Soundproof curtains, 5.5 kg per sq m
- Acoustic carpet and rugs, Felt
-
Reflections
Side wall and ceiling first reflection points at the seating position. A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
- Soundproofing materials, Mass, then decoupling, then cavity absorption, then sealing
- Soundproof curtains, Up to 30 dB
- Acoustic carpet and rugs, 64 sq ft per pack
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate and durability
Durability in Atlanta, before acoustics is discussed
Atlanta is hot dry summers and mild wet winters, and that narrows the material list before acoustics is discussed.
The swing between a dry summer and a wet winter moves timber. PET felt is dimensionally stable across that swing; slat panels want a stable substrate and a ventilated fixing.
The failure we design against here is seasonal movement in timber and winter damp in unheated stock.
On a Atlanta job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.

Where this kind of project usually fails
-
Foam on the walls as a soundproofing measure
It sounds like a small detail until the room is finished and the complaint arrives.
-
A standard door on a room built to hold bass
A 6 mm undercut under a door leaves a hole the size of a brick. The wall around it is then decorative.
-
Treating before the room is sealed
Soundproofing fails at the gaps, not the materials. One unsealed service penetration can undo a correctly built wall.
-
Treating it as a generic Atlanta job
Homes and apartments here are gypsum on studs, which passes low frequency far more easily than masonry. Added mass and a decoupled layer do the work, not absorption.
05 / Supply
What the route into Atlanta actually looks like
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Savannah, then road to Atlanta |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Savannah |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. The sea leg to the US East Coast is long, so plan the full door to door window. We give real dates rather than optimistic ones.
Sea freight into Savannah, then road to Atlanta. Air freight for samples, colour approvals and genuinely urgent quantities.
Questions from Atlanta projects
What makes home theatre soundproofing and acoustics different in Atlanta?
American homes are timber frame with gypsum board on both faces, so a party wall or a basement ceiling has almost no mass. Adding a second leaf with a limp membrane between does more than any amount of surface treatment. A mix room or a stage either isolates or it does not. There is no partial credit, which is why we design the shell before anyone chooses a fabric colour.
Where should the budget go first on a Atlanta project?
Containment. Bass through the wall, floor and door. Mass and decoupling, with the door usually the weakest point. Low frequency inside. Corner absorption with depth, before any surface treatment.
Do you have an office or installation team in Atlanta?
No. We manufacture in India and supply into Atlanta. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Atlanta site?
ships from: Palwal, Haryana, India, arrives at: Savannah, then road to Atlanta, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg to the US East Coast is long, so plan the full door to door window. We give real dates rather than optimistic ones.
What goes wrong most often on this kind of project?
Foam on the walls as a soundproofing measure. A standard door on a room built to hold bass.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
