Auditorium acoustics and soundproofing in Nepal
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem. Temples, function halls and conference rooms are hard volumes carrying amplified speech and music.
- Reverberation time
- Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
- Early reflections
- Shaped surfaces that send energy to the rear seats rather than absorbing everything.
- Rear wall
- The single worst surface in most halls, and the first one to treat.

What this material is and where it earns its place in Nepal
A large hard volume where speech falls apart long before anyone calls the room echoey. The target is intelligibility at the back row, which is a reverberation and early reflection problem, not a loudspeaker problem.
Temples, function halls and conference rooms are hard volumes carrying amplified speech and music.
Work reaching us from Nepal is mostly hotels and guest houses, offices, hospitals, schools, assembly halls, houses.
- Reached entirely by road No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
- Rebuilt and reinforced structures A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.
- Hospitality in dense valleys Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.
- Reverberation time Set against use. Speech and music want different numbers, and a dual use hall needs a decision.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for auditorium acoustics are on the main product page. This page covers what that means for a project in Nepal.
02 / The build-up
The build-up, layer by layer
-
Layer 1
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Nepal, split units and generator sets, with generators close to occupied rooms during outages.
Feature wall only. Slats where they are seen, plain felt elsewhere, to hold the budget where it shows.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Nepal, temples, function halls and conference rooms are hard volumes carrying amplified speech and music.
Over a porous backing. Panel over mineral or PET backing where the room needs genuine low mid control.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Nepal, classrooms are concrete and tile with large class sizes and street noise through open windows.
Zoned. Carpet in the circulation and meeting zones, hard floor elsewhere, so the treatment sits where the noise is made.
For a Nepal practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.
03 / What drives the brief
The Nepal conditions that change the answer
- Reached entirely by road
No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
- Rebuilt and reinforced structures
A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.
- Hospitality in dense valleys
Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.
- Packing for mountain roads
The final leg is often on rough road. We brace and wrap for that rather than for a smooth port transfer.
- Assembly and performance rooms
Temples, function halls and conference rooms are hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are concrete and tile with large class sizes and street noise through open windows.

Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- Ceiling baffles and clouds, 9 to 24 mm
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. A great deal of stock has been rebuilt or retrofitted for seismic performance. Movement joints must stay free and an acoustic layer must not stiffen across them.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Ceiling baffles and clouds, Made to the drawing, standard and custom
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Hotels and guest houses packed into tight streets where street noise reaches rooms through openings rather than walls.
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
- 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
The Nepal climate decides the material list
Nepal is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
Where a consultant is already engaged on a Nepal project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.

Six mistakes that turn into a second fit-out
-
Absorbing the whole room and losing the back rows
This is the one that comes back as a second fit-out rather than a snag.
-
Adding speakers to fix a reverberation problem
It sounds like a small detail until the room is finished and the complaint arrives.
-
Ignoring the rear wall because it is behind the audience
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Nepal job
No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
05 / Getting it there
How material reaches a Nepal site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Overland through the India border, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Road via the India border |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
Overland by road through the India border, then on to site. No sea leg and no port handling.
Questions from Nepal projects
What makes auditorium acoustics and soundproofing different in Nepal?
Temples, function halls and conference rooms are hard volumes carrying amplified speech and music. No port, no container, no sea leg. That keeps lead times short and makes small or repeat orders practical in a way they are not for most export markets.
Where should the budget go first on a Nepal project?
Reverberation time. Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Early reflections. Shaped surfaces that send energy to the rear seats rather than absorbing everything.
Do you have an office or installation team in Nepal?
No. We manufacture in India and supply into Nepal. 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 Nepal site?
ships from: Palwal, Haryana, India, arrives at: Overland through the India border, then road to site, dispatch: 4 to 7 working days. Standard items dispatch in 4 to 7 working days. Grooved panels and custom colours take longer, and we say so before you order, not after.
What goes wrong most often on this kind of project?
Absorbing the whole room and losing the back rows. Adding speakers to fix a reverberation problem.
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
Tell us the room, we will tell you the build-up
We quote from drawings, not from a square foot rate. Send a plan and the section through the critical wall or ceiling and you will get something you can actually build from.
