Acoustic Design & Engineering Services
Room acoustics engineering across Saudi Arabia. RT60 reverberation tuning, NRC absorption modelling, STC sound insulation — for concert halls, theatres, mosques, offices, classrooms, and recording studios. ASTM E90 · ASTM C423 · ISO 3382 · ANSI S12.60 · ASHRAE Ch.48.
— WHAT WE DO —
End-to-end acoustic engineering
Target RT60 ≈ 1.5–2.0 s, Clarity C80 +2 dB, STI 0.65–0.80, NC 25–30. Variable acoustics for multi-genre programmes, hybrid absorber/diffuser systems, and electroacoustic enhancement where the volume can't be increased.
Target RT60 ≈ 2.0–3.5 s (size dependent), STI 0.55–0.65 for Imam speech intelligibility, and per-zone absorption layouts that preserve the architectural Qibla wall while taming the dome and back-wall reflections.
Target Lp,A,S,4m ≤ 50 dBA, DnT,A ≥ 35 dB between zones. Ceiling absorption + screen absorption + sound-masking to reach speech privacy without isolation.
ANSI S12.60 compliance — RT60 ≤ 0.6 s for K-12 classrooms, ≤ 0.5 s for hearing-impaired. STI ≥ 0.65 for clear speech across the back row. Octave-band absorption modelling.
Control rooms tuned to LEDE / NER / RFZ paradigms · iso booths · floating floors · decoupled wall systems for STC ≥ 60 between rooms.
Equipment-source treatment, in-duct silencers, vibration isolation, plant-room enclosure design. ASHRAE Chapter 48 application for HVAC NC targets.
— OUR PROCESS —
From measurement to handover
On-site RT60, background-noise, and STI measurements per ISO 3382 / ANSI S12.60. We test the as-built room before specifying changes.
Octave-band absorption, scatter, and STC modelling. We size every absorber by frequency band so the room hits its targets, not just "feels better."
Project-specific material list with supplier test reports (NRC, αw, STC, fire), drawings, and contractor method statements ready for submittal.
Installation supervision, snag list, and post-handover verification measurement to confirm the room hits the design targets.
