Auditorium acoustics and soundproofing in Al Khobar
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, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief.
- 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 / The material
What you are buying, and what it fixes in Al Khobar
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, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief.
Work reaching us from Al Khobar is mostly control rooms and plant, corporate offices, compound housing, hotels, clinics, schools.
- Industrial noise is a different problem Compressors, generators and process plant are low frequency and structure-borne. Panels on a wall will not touch that. Mass, isolation and sealing will.
- Control rooms and operations centres People sit in these rooms for twelve hours listening to alarms and radios. Intelligibility matters more than a reverberation figure on a sheet.
- Port on the doorstep Dammam is close, so the road leg is short and the landed cost is predictable. That is the practical reason a factory in India can serve this market on schedule.
- 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 Al Khobar.
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 Al Khobar, cooling runs year round at high load, so chillers, AHUs and large duct runs are constant sources. Plant room lining and duct attenuation carry most of the result.
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 Al Khobar, mosques, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief.
Direct to wall. Panel bonded or mechanically fixed flat to the substrate. Simplest, and the weakest at low frequency.
-
Layer 3
Ceiling baffles and clouds
PET felt suspended from the soffit, vertically as baffles or horizontally as clouds. In Al Khobar, new school and university buildings are large, hard and highly glazed. Lecture theatres and sports halls are the spaces that fail first, and ceiling absorption is the practical fix.
Vertical baffles. Hung on edge in rows. Both faces absorb, so coverage figures based on plan area understate them.
Architects working in Al Khobar usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / On the ground
What decides the build-up in Al Khobar
- Industrial noise is a different problem
Compressors, generators and process plant are low frequency and structure-borne. Panels on a wall will not touch that. Mass, isolation and sealing will.
- Control rooms and operations centres
People sit in these rooms for twelve hours listening to alarms and radios. Intelligibility matters more than a reverberation figure on a sheet.
- Port on the doorstep
Dammam is close, so the road leg is short and the landed cost is predictable. That is the practical reason a factory in India can serve this market on schedule.
- Heat, dust and sealed buildings
Buildings stay closed with heavy cooling running year round. Plant noise has nowhere to escape, and rooms get hard and live inside.
- Assembly and performance rooms
Mosques, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief.
- School and campus buildings
New school and university buildings are large, hard and highly glazed. Lecture theatres and sports halls are the spaces that fail first, and ceiling absorption is the practical fix.
04 / Room by room
Where the money goes on a Al Khobar project
-
Reverberation time
Set against use. Speech and music want different numbers, and a dual use hall needs a decision. Compressors, generators and process plant are low frequency and structure-borne. Panels on a wall will not touch that. Mass, isolation and sealing will.
- Wood wool acoustic panels, 1200 x 600 mm
- Wooden slat acoustic panels, 13-3, 14-2, 28-4 and 59-5
- Acoustic carpet and rugs, High density polyester
-
Early reflections
Shaped surfaces that send energy to the rear seats rather than absorbing everything. People sit in these rooms for twelve hours listening to alarms and radios. Intelligibility matters more than a reverberation figure on a sheet.
- Wood wool acoustic panels, 20 mm
- Wooden slat acoustic panels, 2440 x 192 mm and 2440 x 128 mm
- Acoustic carpet and rugs, Felt
-
Rear wall
The single worst surface in most halls, and the first one to treat. Dammam is close, so the road leg is short and the landed cost is predictable. That is the practical reason a factory in India can serve this market on schedule.
- Wood wool acoustic panels, 400 kg per cubic metre
- 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 / Climate and durability
The Al Khobar climate decides the material list
Al Khobar 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.
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.
06 / Worth knowing
Six mistakes that turn into a second fit-out
-
Absorbing the whole room and losing the back rows
It sounds like a small detail until the room is finished and the complaint arrives.
-
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
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Al Khobar job
Compressors, generators and process plant are low frequency and structure-borne. Panels on a wall will not touch that. Mass, isolation and sealing will.
05 / Logistics
Supply into Al Khobar, start to site

Questions from Al Khobar projects
What makes auditorium acoustics and soundproofing different in Al Khobar?
Mosques, conference halls and hotel ballrooms are tall hard volumes where intelligibility over a long reverberation tail is the whole brief. Compressors, generators and process plant are low frequency and structure-borne. Panels on a wall will not touch that. Mass, isolation and sealing will.
Where should the budget go first on a Al Khobar 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 Al Khobar?
No. We manufacture in India and supply into Al Khobar. 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 Al Khobar site?
ships from: Palwal, Haryana, India, arrives at: Dammam, then a short road run across the Eastern Province, 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.
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
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.
