School and classroom acoustics in New York
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet. 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.
- Classroom RT
- A number, set against room volume, achieved mostly at the ceiling.
- Corridor spill
- Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
- Halls and gyms
- Dual use rooms carrying speech, music and sport, where durability decides the product.

01 / The product
What this is, and what it changes in a New York room
Hard floors, bare walls and long corridors that amplify everything. Children with developing language, and anyone with a hearing difficulty, lose more from a live classroom than adults do, which is why intelligibility is the target rather than quiet.
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.
Work reaching us from New York is mostly pre-war apartments, brownstones, offices, studios, restaurants, clinics, schools.
- Boards decide the build-up Co-op and condo rules on floor coverings and separating construction usually set the requirement before any acoustic target does. Get the rule first, then design to it.
- Subway and street Ground level and underground rail put low frequency into the structure. Panels on a wall will not touch it and we will say so.
- Pre-war buildings, timber floors Older stock passes footfall straight down through the joists. A resilient layer under the finish does more than anything applied to the ceiling below.
- Classroom RT A number, set against room volume, achieved mostly at the ceiling.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for school acoustics are on the main product page. This page covers what that means for a project in New York.
02 / The build-up
The build-up, layer by layer
-
Layer 1
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In New York, 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.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 2
Acoustic panels
The full absorber range rather than one product: plain PET felt, printed felt, grooved panels and fabric finishes, chosen by how the room is used and how it has to look. In New York, churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
Mixed finish. Plain felt where it is out of eye line, printed or grooved where it is seen.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In New York, 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.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
If you are specifying for a New York project, we can give you a section, a BOQ and the honest limits of each layer. See how we support architects.

What we see driving New York briefs
- Boards decide the build-up
Co-op and condo rules on floor coverings and separating construction usually set the requirement before any acoustic target does. Get the rule first, then design to it.
- Subway and street
Ground level and underground rail put low frequency into the structure. Panels on a wall will not touch it and we will say so.
- Pre-war buildings, timber floors
Older stock passes footfall straight down through the joists. A resilient layer under the finish does more than anything applied to the ceiling below.
- Depth is expensive here
Floor area costs enough that a wall growing a hundred millimetres into the room is a real number. Thin and effective beats thick and theoretical.
- Assembly and performance rooms
Churches, school gyms and multipurpose halls double as performance spaces, which means a room designed for neither speech nor music has to carry both.
- School and campus buildings
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.

Where the money goes on a New York project
-
Classroom RT
A number, set against room volume, achieved mostly at the ceiling. Co-op and condo rules on floor coverings and separating construction usually set the requirement before any acoustic target does. Get the rule first, then design to it.
- PET felt acoustic panels, 100% PET non-woven, no added binder
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
-
Corridor spill
Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once. Ground level and underground rail put low frequency into the structure. Panels on a wall will not touch it and we will say so.
- PET felt acoustic panels, 9, 12, 18 and 24 mm standard, tolerance plus or minus 5 percent
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic panels, ASTM C423
-
Halls and gyms
Dual use rooms carrying speech, music and sport, where durability decides the product. Older stock passes footfall straight down through the joists. A resilient layer under the finish does more than anything applied to the ceiling below.
- PET felt acoustic panels, 4 to 24 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
The New York climate decides the material list
New York is mild summers and cold, wet winters, and that narrows the material list before acoustics is discussed.
Cold external walls and long heating seasons make condensation behind a lining the thing to design out. PET felt is unaffected by damp air.
The failure we design against here is condensation and cold bridging behind new linings.
Consultants get the raw data, not a sales sheet. That is the whole of our side of the job, and it is set out under working with acoustic consultants.

Six mistakes that turn into a second fit-out
-
Panels at child height where they get damaged
It sounds like a small detail until the room is finished and the complaint arrives.

Treating one classroom and leaving the corridor

Choosing a product that cannot take a football
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.

Treating it as a generic New York job
Co-op and condo rules on floor coverings and separating construction usually set the requirement before any acoustic target does. Get the rule first, then design to it.

Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
Sea freight into the Port of New York and New Jersey, then a short road run to site. Air freight for samples and urgent quantities.
Questions from New York projects
What makes school and classroom acoustics different in New York?
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. Co-op and condo rules on floor coverings and separating construction usually set the requirement before any acoustic target does. Get the rule first, then design to it.
Where should the budget go first on a New York project?
Classroom RT. A number, set against room volume, achieved mostly at the ceiling. Corridor spill. Long hard circulation feeds every room off it. Treating the corridor helps every classroom at once.
Do you have an office or installation team in New York?
No. We manufacture in India and supply into New York. 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 New York site?
ships from: Palwal, Haryana, India, arrives at: Port of New York and New Jersey, then a short road run, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. The sea leg from India is long, so plan the full door to door window into the programme. We give real dates, not optimistic ones.
What goes wrong most often on this kind of project?
Panels at child height where they get damaged. Treating one classroom and leaving the corridor.
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.
Next step
Drawings in, BOQ and a delivered date out
A plan and a section is enough. We will come back with a build-up, a BOQ and a delivered date, and we will say so if what you are asking for will not work.
