Acoustic Engineering Systems soundproofing · treatment · engineering — built for Saudi Arabia

At Yamamah Smart, we design and deliver advanced acoustic engineering systems for soundproofing, noise control, and interior acoustic treatment. Our solutions reduce unwanted noise, control sound reflection, improve speech clarity, and create healthier and more comfortable environments — for offices, mosques, halls, hotels, studios, schools, and commercial buildings.

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.

*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.

🧱

Mass-Loaded Vinyl

1-2 lb/ft² (~5-10 kg/m²) · ~2.7-6.4 mm

High-density flexible barrier. The mass component that physically blocks airborne sound. Standard SKUs per ASTM E90 testing.

🌫️

Rock / Mineral Wool

50-100 mm · 40-80 kg/m³

Acoustic-grade mineral wool. The damping component that converts sound energy to heat. NRC measured per ASTM C423.

📋

Gypsum Board

12.5 mm (½″) · 15.9 mm (⅝″ Type-X)

Structural face layers. The surface finish — single, double, or staggered. Manufactured to ASTM C1396.

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.

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.
