About Geonoise
Thailand's independent acoustic Center of Excellence — 40+ years of experience.
Geonoise is the most specialised acoustic and vibration consultancy in Thailand. We are genuinely independent — we sell expertise and outcomes, not products — so there is no conflict of interest in the solutions we recommend.
Founded in 2006 by Michel Rosmolen — Vice President of the Society of Acoustics (Singapore) and IIAV Director for South-East Asia — our senior engineers bring 40+ years of experience, hold international roles (IIAV, ICSV), use Norsonic-grade equipment calibrated to ISO/IEC 17025 and SoundPLAN modelling, and produce reports referencing ISO 9613-2 that are defensible in legal, EIA, and regulatory contexts.
As a Center of Excellence we don't just meet the standard — we set it and teach it, through Geonoise Academy, raising the bar for acoustics in Thailand and connecting to our partner network across ASEAN.
What sets us apart from material sellers and general noise-measurers is calibrated, standards-grade equipment, genuinely credentialed engineers, and reports that protect you when they have to stand as evidence.
A quality system you can audit, not a claim you have to take on trust
Most acoustic consulting in Thailand runs without an externally audited quality system. Ours does not. From how a job is accepted, to how instruments are calibrated, to how site data is captured, reviewed and signed off — every step is documented and audited on a regular cycle.
ISO 9001:2015
Certified quality management system covering our consulting, measurement and reporting processes.
ISO/IEC 17025
Instrumentation calibrated with certificates traceable to international standards; evidence-grade measurement issued through the ALT laboratory.
