Recording studio acoustics and soundproofing in Dehradun
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later. Very little purpose built studio work. Most demand is hotel entertainment space and small content rooms inside existing hillside buildings.
- Isolation
- A measured background level, agreed before anything is bought.
- Low frequency
- Corner and boundary absorption with real depth, not surface foam.
- Early reflections
- Controlled at the mix position, and only there.

01 / The product
What this material is and where it earns its place in Dehradun
Two jobs that must not be confused: keeping the building out, and making the room honest inside. The first is mass and decoupling and has to be built first. The second is absorption and diffusion and can be tuned later.
Very little purpose built studio work. Most demand is hotel entertainment space and small content rooms inside existing hillside buildings.
Work reaching us from Dehradun is mostly boarding schools and colleges, assembly halls, dormitories, hotels, hospitals, offices.
- Classrooms defeat the teacher Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
- Halls used for everything Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second.
- Dormitories Children sleeping next to corridors and each other. Partition and door detailing does more than anything applied inside the room.
- Isolation A measured background level, agreed before anything is bought.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for studio soundproofing are on the main product page. This page covers what that means for a project in Dehradun.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Acoustic foam and BassBloc
Open cell foam shapes for high frequency control, and BassBloc, a high density absorber built for the low mid range where ordinary foam does nothing. In Dehradun, hotel plant, boilers and generator sets close to guest rooms in compact hillside buildings.
First reflection points. Mirror trick placement on side walls and ceiling, which is a handful of panels rather than a lined room.
-
Layer 2
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Dehradun, hotel banquet rooms, auditoria and temple halls are hard volumes carrying amplified speech and music.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 3
Soundproof curtains
A layered curtain with a mass loaded vinyl core, used where an opening has to stay an opening. In Dehradun, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Track with a seal. Ceiling track plus a floor seal or drape, so the perimeter is closed when it is drawn.
If you are specifying for a Dehradun 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 Dehradun briefs
- Classrooms defeat the teacher
Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
- Halls used for everything
Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second.
- Dormitories
Children sleeping next to corridors and each other. Partition and door detailing does more than anything applied inside the room.
- Next day from the plant
A short run, so freight stays low and samples arrive before the order.
- The housing stock
RC frame houses and hotels built on slopes, with hard floors and cold external walls in the hill towns.
- The studio and content scene
Very little purpose built studio work. Most demand is hotel entertainment space and small content rooms inside existing hillside buildings.

Low frequency
Corner and boundary absorption with real depth, not surface foam. Assembly, examinations, performances and sport in one room. The design has to work for speech first and music second.

Early reflections
Controlled at the mix position, and only there. Children sleeping next to corridors and each other. Partition and door detailing does more than anything applied inside the room.

Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Conditions
Why the climate in Dehradun changes the material, not the target
Dehradun 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.
On a Dehradun job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Before you buy
Six mistakes that turn into a second fit-out
-
Buying foam to solve an isolation problem
Small on the drawing, expensive on site, and almost always found after handover.
-
Treating the room before the shell is isolated
This is the one that comes back as a second fit-out rather than a snag.
-
Killing the room completely and calling it controlled
More absorption is not better absorption. Past the target the room goes flat and people raise their voices to compensate.
-
Treating it as a generic Dehradun job
Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
05 / Logistics
How material reaches a Dehradun site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | next day |
| Dispatch | 2 to 4 working days |
| To site | next day |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly three hundred kilometres, normally next day on a dedicated truck.
Questions from Dehradun projects
What makes recording studio acoustics and soundproofing different in Dehradun?
Very little purpose built studio work. Most demand is hotel entertainment space and small content rooms inside existing hillside buildings. Hard floors, high ceilings and hard plaster mean a teacher raises their voice all day. Absorption on the ceiling recovers most of it.
Where should the budget go first on a Dehradun project?
Isolation. A measured background level, agreed before anything is bought. Low frequency. Corner and boundary absorption with real depth, not surface foam.
Do you have an office or installation team in Dehradun?
No. We manufacture in India and supply into Dehradun. 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 Dehradun site?
made at: Our own plant, Palwal, Haryana, reaches site in: next day, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. 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?
Buying foam to solve an isolation problem. Treating the room before the shell is isolated.
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.

Tell us the room, we will tell you the build-up
One drawing gets you a proper answer. Build-up, quantities, a delivered date, and an honest note on anything we think is the wrong approach.
