— Three Engineered Systems —
Block sound. Tame echo.
Engineer the outcome.
Each system is engineered based on the project requirements, room function, noise source, surface materials, and acoustic performance targets — from design and material selection to supply and installation.
Soundproofing
Reduce sound transmission between rooms or from outside to inside. Includes soundproof walls, acoustic doors, sound barriers, and multilayer materials such as MLV and acoustic insulation.
Acoustic Treatment
Improve sound quality inside a space by reducing echo and controlling RT60. Uses fabric panels, PET panels, perforated wood, acoustic foam, and ceiling baffles.
Design & Engineering
Site study, noise measurement, RT60 analysis, material selection, and customized solutions per project. The engineering layer that ties soundproofing and treatment together.
— SYSTEM 1 —
Soundproofing Systems
Stop sound from crossing walls, floors, and ceilings. The physics is mass + decoupling + damping. We engineer the full envelope — drywall, MLV, isolation clips, acoustic doors and seals — to hit your STC and IIC targets for halls, mosques, offices, hotels, and villas.
per ASTM E90 / E413 testing
Sound Insulation Targets
PER PUBLISHED INTERNATIONAL STANDARDS · BY SPACE TYPE
*No published Saudi Building Code (SBC) Rw/STC value exists for mosques — the figure shown is a Yamamah Smart engineering recommendation, not a regulatory requirement. STC and Rw are closely related (per ASTM E413 / ISO 717-1) but not identical (typically within ±2 dB).
Mass
Heavy materials (MLV, concrete) — physically resist vibration.
Decoupling
Resilient channels, staggered studs — break the structural path.
Damping
Mineral wool, viscoelastic compound — convert energy to heat.
Sealing
Acoustic sealant, gaskets — close every leak. A small leak (<1% area) can drop wall STC by 15-30 dB.
— OUR APPROACH —
Engineered per project
We do not sell pre-packaged "wall systems". Every space — mosque, hall, office, hotel, villa — is engineered around its own Rw target, budget, and architecture. The right material stack and thicknesses are determined after site survey and acoustic simulation per ISO 717-1.

Acoustic Treatment Systems
Inside the room, sound bounces off every hard surface. Our treatment systems control reflections, RT60, and clarity — through wall and ceiling panels, diffusers, bass traps, and decorative acoustic finishes tuned to each frequency band.
Panel Types & NRC Range
PER ASTM C423 · TYPICAL TYPE A MOUNTING
NRC RANGES = TYPICAL LAB-TESTED VALUES PER ASTM C423 · ACTUAL VALUE DEPENDS ON THICKNESS, DENSITY & MOUNTING (TYPE A DIRECT VS TYPE E-400 AIR GAP)
Target depends on room volume & function
Ceiling (priority 1)
Largest surface, most cost-effective. Suspended grid or direct mount. Typical target NRC ≥ 0.80 (per ASTM C423).
Walls (priority 2)
First-reflection points + back wall. Mid-height treatment. Typical target NRC ≥ 0.70.
Hanging Baffles
Open-plan offices, double-height halls. Bidirectional absorption (both faces) — high effective absorption per unit area.
