Consultants in Acoustics, Noise, and Vibration


For almost 30 years, CSTI acoustics has worked with clients in North & South America, Europe, and Asia.


In North America alone, we have worked in 37 of the 50 states and Puerto Rico; two of the 10 provinces of Canada, and two of the 10 largest cities in Mexico.

CSTI acoustics continues to acquire and develop new and exciting technologies in acoustics, noise, and vibration control in order to provide excellent results within the proposed timeframe and the approved budget.




A woman-owned business, CSTI acoustics has had the privilege of working on a variety of projects for many different customers, from large multinational corporations to small, privately held firms—and even individual homeowners.


We have worked with some of the world’s leading energy, engineering, and manufacturing companies, from BP, Chevron, ExxonMobil, Phillips 66, and Shell to Wood Group Mustang, Fluor, GE, Hyundai, Raytheon, and Siemens.

Our clients also include transportation companies, like Goodyear; technology firms, like IBM, Microsoft, and Texas Instruments; chemical companies, like BASF and Dow, and general merchandisers, like HEB, J. C. Penney, Kroger, and Walmart.




Our niche is acoustics, noise, and vibration control, but it’s not limited to just one industry.


CSTI acoustics has worked for energy companies and EPC (Engineering, Procurement, and Construction) firms; architects and developers; churches and universities; transportation companies and technology firms; manufacturers and musicians; federal agencies and local governments, and general merchandisers and charities.


So whether you are Nabisco or Anheuser-Busch, Six Flags or the Mall of America, Good Shepherd Methodist Church or MD Anderson Cancer Center, we can help.

Remember, minimizing noise and vibration and maximizing the sounds that we want to hear isn’t particular to one kind of business—it’s part of life.


CSTI acoustics provides excellent service, from a wealth of experience and dedication to the task at hand.


Principal Consultants

Robert D. Bruce, P.E., INCE.Bd.Cert.

Arno S. Bommer, INCE.Bd.Cert.

Bob Bruce specializes in the solution of acoustical problems. He has investigated occupational noise exposures, hearing loss, structural fatigue, community annoyance, and vibration problems.

Bob has solved noise problems in the following industries: aerospace, automobile, chemical, cogeneration, food, gas compression, lumber, metals, oil, plastics, power, rubber, and textile.

Bob has analyzed noise problems from aircraft, airports, missiles, highways, rapid transit systems, railroads, racecars, and hovercraft.

He has designed acoustical treatments for concert halls, churches, hospitals, office buildings, recreational centers, shopping malls, and university buildings

For more than 40 years and on thousands of projects, Bob has shared with his clients and colleagues his knowledge of acoustical measurements, noise control, vibration, and building acoustics.

He has written chapters on measurements and control techniques for sound and vibration in 11 books and has published over 40 technical papers related to building acoustics, environmental noise, and industrial noise and vibration.

Since 1982, Arno Bommer has worked on acoustical projects ranging from offshore platform noise control to National Park sound surveys to church acoustics. He has worked in both the planning stage, when problems must be anticipated and avoided, and after completion, when existing problems need to be treated.

In the field of industrial noise and vibration control, Arno has worked on cogeneration plants, petrochemical plants, compressor stations, materials processing plants, and aircraft manufacturing facilities. These projects have involved reducing in-plant and community noise levels. On turn-key noise control projects, Arno designed noise control treatments, took his plans to bid, and supervised installation of treatments.

Arno has investigated transportation noise from aircraft, automobiles, boats, buses, dredges, forklifts, front-end loaders, hovercraft, racecars, trains, and trucks. He has also investigated vibration from railroads and pile driving.

For offices and residential buildings, Arno has designed walls and ceilings to improve noise isolation and/or speech privacy. He has designed noise control treatments for mechanical equipment including computers, transformers, elevators, HVAC systems, chillers, compressors, pumps, and cooling towers.

In the field of room acoustics, Arno has specified room shaping and surface materials to improve speech intelligibility and music presentation in churches, theaters, conference rooms, museums, and auditoria.

Arno has written and used computer models to analyze sound propagation and to determine the effectiveness of proposed noise control treatments.

In cases involving litigation, Arno has collected and analyzed noise data, investigated noise requirements, written reports, and served as an expert witness.
