Board-Certified Acoustical Engineering · Since 1990
CSTI Acoustics helps refineries, plants, developers, and attorneys measure, model, and mitigate noise and vibration — from OSHA hearing-conservation compliance to courtroom expert testimony.
What we do
Whether it's a worker-exposure limit, a building's sound isolation, or a disputed decibel in court, the physics is the same — and so is the rigor we bring to it.
Protecting workers and neighbors from hazardous noise at refineries, petrochemical plants, LNG, compressor stations, and power generation.
Industrial services →Sound isolation, room acoustics, and community-noise studies for buildings, developments, and land-use — designed to meet code and keep the peace.
Architectural services →Board-certified expert-witness testimony and forensic acoustical analysis for noise disputes, nuisance and ordinance cases, and workplace exposure claims.
Litigation support →
Where noise carries consequences
Thirty-five years measuring, modeling, and mitigating sound where it matters most.
Who you work with
No account managers, no hand-offs to junior staff. When you engage CSTI, you work directly with a board-certified acoustical engineer.
Board-certified acoustical engineer working since 1982 across the full range of industrial and architectural acoustics — from offshore-platform and petrochemical noise control to National Park sound surveys and the acoustics of worship and performance spaces. He leads every engagement from measurement through mitigation.
CSTI was founded in 1990 by Robert D. "Bob" Bruce, P.E. — a Fellow of the Acoustical Society of America and a past president of the Institute of Noise Control Engineering (INCE/USA). Over 40+ years he authored 35+ publications and 12 book chapters that helped define how industrial noise is measured and controlled.
Who we serve
Across three decades, CSTI has served Gulf-Coast energy operators, national manufacturers, design teams, government agencies, and the attorneys who litigate noise — anonymized here by type, named on request under engagement.
