Venue and restaurant acoustics in Ethiopia
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other. Church buildings and conference halls are tall hard volumes with long reverberation.
- Containment
- Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
- Table level comfort
- Absorption at the ceiling so guests stop raising their voices at each other.
- Entrance and service
- Doors, lobbies and extract paths, which is where most of the leakage actually is.

01 / The product
What you are buying, and what it fixes in Ethiopia
Two different jobs that get quoted as one: keeping bass inside the building for the neighbours, and making the room comfortable enough that guests can talk. Solving one does nothing for the other.
Church buildings and conference halls are tall hard volumes with long reverberation.
Work reaching us from Ethiopia is mostly industrial parks, offices, hotels, places of assembly, schools, hospitals.
- Landlocked, so the road leg counts Djibouti then several hundred kilometres by road. We quote the sea leg and the road leg separately so the date is honest.
- Packing has to survive the run A long road leg on mixed surfaces is hard on a pallet. We brace and wrap for that rather than for a short port transfer.
- Industrial parks at scale New manufacturing built quickly, where enclosure and partition detail can still be designed in rather than retrofitted.
- Containment Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for venue soundproofing are on the main product page. This page covers what that means for a project in Ethiopia.

02 / The build-up
What goes where, from the structure in
-
Layer 1
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Ethiopia, split units and generator sets, with mechanical plant close to occupied areas.
Resilient bar. Where a full independent leaf will not fit. Effective, and very easy to short circuit with one wrong screw.
-
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 Ethiopia, church buildings and conference halls are tall hard volumes with long reverberation.
Ceiling first. In most rooms the ceiling is the largest untreated surface and the cheapest square metre of result.
-
Layer 3
Wooden slat acoustic panels
Timber slats on an acoustic backing. In Ethiopia, classrooms are concrete and hard surfaced with large class sizes and long corridors.
Slats on felt backing. The standard. Absorption comes from the backing behind the gaps, so the slat gap ratio is an acoustic decision, not only a visual one.
We would rather argue about the build-up at design stage than on site. See how we support architects.
03 / Local conditions
What we see driving Ethiopia briefs
- Landlocked, so the road leg counts
Djibouti then several hundred kilometres by road. We quote the sea leg and the road leg separately so the date is honest.
- Packing has to survive the run
A long road leg on mixed surfaces is hard on a pallet. We brace and wrap for that rather than for a short port transfer.
- Industrial parks at scale
New manufacturing built quickly, where enclosure and partition detail can still be designed in rather than retrofitted.
- Large assembly spaces
Halls and civic spaces built in concrete where speech fails long before the room is called echoey.
- Assembly and performance rooms
Church buildings and conference halls are tall hard volumes with long reverberation.

Where the money goes on a Ethiopia project
-
Containment
Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Djibouti then several hundred kilometres by road. We quote the sea leg and the road leg separately so the date is honest.
- Acoustic panels, 9 to 24 mm, 1220 x 2440 mm standard, up to 2440 x 4270 mm, 1200 to 3600 GSM
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Acoustic carpet and rugs, High density polyester
-
Table level comfort
Absorption at the ceiling so guests stop raising their voices at each other. A long road leg on mixed surfaces is hard on a pallet. We brace and wrap for that rather than for a short port transfer.
- Acoustic panels, 1800 x 900 mm, image printed into the felt rather than onto a facing
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Acoustic carpet and rugs, Felt
-
Entrance and service
Doors, lobbies and extract paths, which is where most of the leakage actually is. New manufacturing built quickly, where enclosure and partition detail can still be designed in rather than retrofitted.
- Acoustic panels, Cut pattern in PET felt, adds visual rhythm without changing the absorber
- Wooden slat acoustic panels, 14, 16 and 18 mm
- Acoustic carpet and rugs, 64 sq ft per pack
Designers get colour, pattern and CNC options with the absorption figure attached to each. See how we work with interior designers.
04 / Durability
What the Ethiopia climate rules in and rules out
Ethiopia is warm and humid through most of the year, with a long wet season, and that narrows the material list before acoustics is discussed.
Humidity is the deciding factor. PET felt does not absorb moisture, shed fibre or feed mould, which is why it outlasts fabric-wrapped mineral wool in this climate. Wood wool and timber need a ventilated cavity behind them.
The failure we design against here is mould, sagging fabric finishes and swelling in timber.
Where a consultant is already engaged on a Ethiopia project, we supply to their specification and send the test reports rather than describing them. More on working with acoustic consultants.
06 / Before you buy
The six errors that cost the most
-
Panels on the wall as a neighbour noise solution
It sounds like a small detail until the room is finished and the complaint arrives.
-
A lobby with both doors able to open at once
A gap undoes the partition it sits in. Sealing is the cheapest line on the quote and the first one to get cut.
-
Extract ducting that bypasses every wall you built
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 Ethiopia job
Djibouti then several hundred kilometres by road. We quote the sea leg and the road leg separately so the date is honest.
05 / Logistics
How material reaches a Ethiopia site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Djibouti, then road inland to Addis Ababa |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Djibouti, then road |
| 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.
Sea freight into Djibouti, then road inland to Addis Ababa and beyond. Air freight for samples and urgent quantities.
Questions from Ethiopia projects
What makes venue and restaurant acoustics different in Ethiopia?
Church buildings and conference halls are tall hard volumes with long reverberation. Djibouti then several hundred kilometres by road. We quote the sea leg and the road leg separately so the date is honest.
Where should the budget go first on a Ethiopia project?
Containment. Low frequency through structure to flats above and beside. Mass, decoupling and a sealed envelope. Table level comfort. Absorption at the ceiling so guests stop raising their voices at each other.
Do you have an office or installation team in Ethiopia?
No. We manufacture in India and supply into Ethiopia. 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 Ethiopia site?
ships from: Palwal, Haryana, India, arrives at: Djibouti, then road inland to Addis Ababa, 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?
Panels on the wall as a neighbour noise solution. A lobby with both doors able to open at once.
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.

Drawings in, BOQ and a delivered date out
Send what you have. We will give you a layer by layer build-up, a bill of quantities and a date material lands, and we will flag anything in the brief that will not achieve what you want.
