Auditorium acoustics and soundproofing in Egypt
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. Mosques, churches and cinema halls are large 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.

01 / What it is
The product, described honestly, for a Egypt brief
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.
Mosques, churches and cinema halls are large hard volumes carrying amplified speech and music.
Work reaching us from Egypt is mostly new development and government buildings, hotels and resorts, offices, hospitals, schools, venues.
- Convenient sailings Our routes to Europe already pass this way, which keeps frequency good and freight competitive.
- Development at scale Very large single orders where the same detail repeats across many buildings. Batch consistency matters more than the figure on one sheet.
- Heat, dust and sealed buildings Closed up with heavy cooling, so plant noise accumulates inside and rooms stay hard and live.
- 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 Egypt.
02 / The build-up
What goes where, from the structure in
-
Layer 1
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Egypt, split units and generator sets, with condensers in light wells that channel noise back into every flat.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
-
Layer 2
PET felt acoustic panels
A rigid non-woven panel pressed from 100% polyester fibre, a large part of it recycled. In Egypt, mosques, churches and cinema halls are large hard volumes carrying amplified speech and music.
On a 25 to 50 mm air gap. The same panel on battens. The air gap moves absorption down in frequency at no extra material cost, and is the cheapest improvement available.
-
Layer 3
Acoustic carpet and rugs
A tile carpet with a dense polyester face on a felt backing. In Egypt, classrooms are concrete and tile with very large class sizes and street noise through open windows.
Over a resilient underlay. Where impact noise to the floor below is the actual complaint, the underlay does that work, not the carpet.
For a Egypt practice, the useful thing is a detail you can put in a drawing set, not a brochure. See how we support architects.

What decides the build-up in Egypt
- Convenient sailings
Our routes to Europe already pass this way, which keeps frequency good and freight competitive.
- Development at scale
Very large single orders where the same detail repeats across many buildings. Batch consistency matters more than the figure on one sheet.
- Heat, dust and sealed buildings
Closed up with heavy cooling, so plant noise accumulates inside and rooms stay hard and live.
- Assembly and function spaces
Large halls in concrete and stone where speech stops being intelligible well before the room sounds wrong.
- Assembly and performance rooms
Mosques, churches and cinema halls are large hard volumes carrying amplified speech and music.
- School and campus buildings
Classrooms are concrete and tile with very 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. Our routes to Europe already pass this way, which keeps frequency good and freight competitive.
- Wooden slat acoustic panels, MDF, FR MDF, HDF or HDHMR
- 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
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. Very large single orders where the same detail repeats across many buildings. Batch consistency matters more than the figure on one sheet.
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- 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
-
Rear wall
The single worst surface in most halls, and the first one to treat. Closed up with heavy cooling, so plant noise accumulates inside and rooms stay hard and live.
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- PET felt acoustic panels, 1220 x 2440 mm standard, 4 x 8 ft
- Ceiling baffles and clouds, ASTM C423
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
Durability in Egypt, before acoustics is discussed
Egypt is hot and dry for most of the year, with dust and high daytime surface temperatures, and that narrows the material list before acoustics is discussed.
Dust is the enemy of open-cell products. PET felt does not shed, does not hold dust in the way fabric-wrapped glass wool does, and wipes down. Timber needs a stable indoor RH or it moves.
The failure we design against here is dust ingress and thermal movement in long runs.
On a Egypt 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
-
Absorbing the whole room and losing the back rows
Small on the drawing, expensive on site, and almost always found after handover.
-
Adding speakers to fix a reverberation problem
This is the one that comes back as a second fit-out rather than a snag.
-
Ignoring the rear wall because it is behind the audience
This is the one that comes back as a second fit-out rather than a snag.
-
Treating it as a generic Egypt job
Our routes to Europe already pass this way, which keeps frequency good and freight competitive.
05 / Getting it there
How material reaches a Egypt site
| Ships from | Palwal, Haryana, India |
|---|---|
| Arrives at | Alexandria, Port Said or Sokhna, then road to site |
| Dispatch | 4 to 7 working days |
| Freight | Sea via Alexandria or Port Said |
| 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 Alexandria, Port Said or Sokhna, then road to site. Air freight for samples and urgent quantities.
Questions from Egypt projects
What makes auditorium acoustics and soundproofing different in Egypt?
Mosques, churches and cinema halls are large hard volumes carrying amplified speech and music. Our routes to Europe already pass this way, which keeps frequency good and freight competitive.
Where should the budget go first on a Egypt 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 Egypt?
No. We manufacture in India and supply into Egypt. 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 Egypt site?
ships from: Palwal, Haryana, India, arrives at: Alexandria, Port Said or Sokhna, 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.
