Our Services
Comprehensive, independent acoustic consulting — pick the service that matches your problem.
Building Acoustics
ISO 16283 field testing, architectural design review, and noise control for residential, hotel, and commercial buildings.
Environmental Noise (EIA)
Environmental Impact Assessment noise studies, ISO 1996 surveys, and community noise management plans.
Industrial & Occupational
Factory noise assessments, workplace hearing protection programs, and end-of-line noise quality control.
Legal & Regulatory
Expert witness reports, noise compliance surveys, and evidence documentation for legal proceedings.
City Noise Mapping
Strategic noise mapping, action plans, and urban noise management for municipalities.
AV & Speech Intelligibility
STI measurement, AV system commissioning, and speech intelligibility testing for public spaces.
Hotel & Resort Acoustics
Design and test guest-room isolation, floor impact, MEP systems, and ballrooms to international standards — with pre-opening verification.
Office & Workplace Acoustics
Balance speech privacy with collaboration — reverberation, background noise, meeting-room confidentiality, and sound masking to standards and green-building criteria.
Vibration Monitoring & Analysis
Construction and blasting vibration measurement to DIN 4150-3, online building monitoring with real-time alerts, and machine condition assessment to ISO 10816.
Rolling Stock Acoustics & Ride Comfort
Exterior and interior noise, driver's cab, ride comfort and PA intelligibility measurement for metro, EMU and locomotive projects — to ISO 3095, ISO 3381, EN 15892 and EN 12299.
Acoustic Contract & Guarantee Review
Have the acoustic clauses in a turnkey quotation read by someone who does not profit from them — before you sign.
Noise Modelling & Prediction
Predict noise before it is built. SoundPLAN modelling to ISO 9613-2 for industrial sites, roads, rail and developments — contour maps, façade levels and mitigation options compared on paper, not on site.
Acoustic Product Development & R&D
Your panel, door or machine did not reach the rating it needed. We find out why and what to change — troubleshooting, design optimisation, prototype development and competitive benchmarking for manufacturers.
Noise Monitoring as a Service
Continuous monitoring without buying the instruments. Class 1 stations, live dashboard, threshold alerts and compliance reporting — installed, calibrated and maintained by us, on a monthly or project fee.
Corporate Acoustic Compliance Programmes
Noise compliance managed as an annual cycle, not a panic. Scheduled occupational and boundary surveys, a measurement record that builds year on year, annual review and site training.
Expert Witness & Forensic Acoustics
Independent acoustic evidence for disputes, arbitration and litigation. Forensic investigation, review of the other side's report, expert reports and testimony — for either party, in Thai or English.
Acoustic Due Diligence
Know the acoustic risk before you sign. Pre-acquisition assessment, development site screening, vendor warranty verification and pre-handover testing — the defect nobody checks for and everybody inherits.
Acoustic Data & AI Monitoring
Continuous acoustic data, automatically classified and engineer-verified. AI detects and sorts the events; a named acoustic engineer verifies and signs the result — so you get evidence, not an algorithm's opinion.
Acoustic Camera & Noise Source Identification
Which machine, valve, panel or roof joint is actually making the noise — shown on a picture, ranked and measured. 128-microphone real-time acoustic imaging for plants, buildings and disputes, with before-and-after verification.
Hearing Conservation Programme
Required by law once any employee's 8-hour exposure reaches 85 dBA. Plant noise survey, noise contour map, personal dosimetry and the complete written programme to the DLPW B.E. 2561 notification — measured under real production, signed by a licensed noise analyst.
Low-Frequency Noise & Hum Investigation
The hum that keeps people awake while the dBA meter says compliant. Spectral and tonality analysis, vibration correlation and switch-off tests to identify a transformer, chiller or pump — and the path it travels — before anyone pays for the wrong fix.
Generator, Chiller & Rooftop Plant Noise
Standby generators, chillers, cooling towers and extract fans against the night-time and nuisance limits. Predicted before purchase, measured during tests, in-situ silencer and sound-power verification, and vendor guarantees checked before the retention is released.
Field Measurement Capability
What we can measure on site, and to which standard. ISO 1996, 16283, 3382, 16032, 9614-2/-3 sound intensity, 3747 in-situ sound power, 11820 silencers, 10848-2 flanking, DIN 4150-3 and more — with the instruments we bring and the calibration behind them.
Field Sound Insulation Testing (STC / DnT,w)
STC test on site: airborne, impact and façade sound insulation measured in the finished building to ISO 16283 and ASTM E336 — DnT,w, R'w, ASTC and L'nT,w for condominium handover, hotel brand audits, fit-out acceptance and disputes. Laboratory STC (ASTM E90) is tested by the ALT laboratory.
PAGA & Voice Alarm Testing (STIPA)
Live STI (STIPA) and alarm audibility testing of PAGA, voice evacuation and fire alarm systems, indoors and outdoors, to IEC 60268-16, ISO 7240-19, BS 5839 and NFPA 72. Independent commissioning witness for plants, terminals, hospitals and high-rise buildings.
Speech Intelligibility Prediction (STI)
Design-stage STI calculation for PA, voice alarm and PAGA systems: a 3D acoustic model, STI maps per zone, and the loudspeaker layout and acoustic treatment checked against the specification before anything is installed.
