Soundproofing for theatres and halls: stopping noise getting in or out

How we approach soundproofing

Three principles govern isolation: mass (heavier materials isolate more), decoupling (two unconnected leaves beat one thick leaf) and sealing (any small gap weakens the whole wall). Good isolation therefore uses double walls with a cavity and mineral wool, and careful details at doors and services.

Flanking paths cause many failures: sound travelling through a shared suspended ceiling, HVAC ducts or a continuous floor. We treat the room as a complete box, not a single wall.

In sensitive rooms such as cinemas and studios, a room-within-a-room may be needed, with a floating floor and independent walls and ceiling on resilient mounts.

Project types

• Isolating theatres and cinemas from surroundings
• Meeting rooms and executive offices
• Studios and recording rooms
• Plant and generator rooms
• Apartments and villas

Project phases

1. Identifying noise sources — External, internal and paths.
2. Target — Required isolation and quietness.
3. Design — Wall, floor, ceiling and door details.
4. Construction — Sealed works with concealed works documented.
5. Testing — Measurement on request.

Applications and clients

• Theatres and cinemas
• Hotels
• Offices
• Studios

We deliver soundproofing first in Saudi Arabia: Riyadh where we are based, then Jeddah and the Makkah region, Dammam and Khobar in the Eastern Province, Makkah and Madinah, and other regions. Beyond that we serve GCC countries (UAE, Qatar, Kuwait, Bahrain and Oman), aligning with each country’s local requirements, and we review international requests case by case.

Checklist before you start

• Is the problem sound transfer (isolation) or internal echo (treatment)?
• Has existing and target reverberation been measured or calculated?
• Have flanking paths such as ceilings and ducts been identified?
• Do materials have tested absorption or isolation values?
• Is the fire classification suitable for a public space?
• Is treatment integrated into the interior design?

Common mistakes we help you avoid

• Using foam to soundproof
• Covering every wall with absorbers so the room goes dead
• Neglecting doors and openings in isolation projects
• Relying on an absorption coefficient without knowing the tested mounting

Requirements in Saudi Arabia

Acoustic materials in public spaces in the Kingdom must meet the approved fire-protection requirements, so we request supplier test certificates and check them against the project specification before procurement.

What you receive

• An initial technical notes report after drawing review or site visit
• A clear itemised scope of work
• Approved drawings and specifications before construction
• A programme linked to project stages
• Records of concealed works and handover with documents and training

How to prepare your request

To speed up the study, prepare what you have: the architectural plan (PDF or CAD), building sections and clear heights, the expected audience size, the main uses in order of importance, photos of the existing site if any, and the target programme. The information need not be complete; helping you complete it is part of our work.
