SRAcoustics was formed in 1987 to provide comprehensive consulting services in architectural acoustics, HVAC noise control, sound, audiovisual and television systems. Stan Roller is the principal and partner consultant for SRAcoustics. 

Our continuous personal involvement ensures a combination of creative and well thought-out designs with a willingness to communicate throughout the project. We typically work under the direction of the Architect as part of the design team and pride ourselves as viable, even-tempered team members. We consider ourselves to be the owner's personal acoustics representative on the design team.

We work on all building types, but we specialize in theaters, auditoriums, religious buildings, music halls, music buildings, recording and television studios, government buildings, gymnasiums, stadiums, hospitals, school and university facilities. We provide resource information to the design team and to the owner.  Recommendations are made in meetings, letter reports, drawings, emails, and telephone discussions as required.

Comprehensive budget information and documents are prepared for sound and related systems with final drawings and specifications for inclusion in the Architect's bid package. For architectural acoustics and mechanical system design, information is drafted suitable for incorporation into drawings by the Architects and their Engineers.

We are available to work during all phases of a project. We can follow-up our basic recommendations with bid and shop-drawing reviews, construction site visits, and conformance testing after work completion. Our offices are equipped with CAD facilities, and our drawings are produced on AutoCAD, AutoDesk Revit, Google Sketch-up, or as required by the project.  Our consultants use the latest computer-based programs for acoustic and systems design (where applicable) and provide file documentation.  Our services are supported by a full complement of company-owned acoustic and sound measurement instruments.


Project checkouts include acoustic tests, HVAC noise measurements, documentation as well as the tuning and balancing of sound systems. We have a strong ability and the experience to apply acoustic theory in a viable and creative way to a building so it will successfully meet the requirements for drama, dance, music and other communication uses.

We consider all aspects of the design to be important and we understand the need to work within the budget framework of the designated project.  Our goal is to maximize the acoustic performance of the project while establishing where compromise is appropriate.  We work diligently at maximizing user-friendly systems as well as providing a high acoustic performance that is both aesthetically pleasing and well suited for a multitude of needs.


SRA is a group of independent consultants. We do not represent any manufacturers, resellers, or distributers of acoustical products, sound/video equipment or other components. This allows us to provide our clients with completely unbiased designs and recommendations. We are the owner’s acoustic and technical representative to the design team.

Sound Isolation

SRAcoustics keeps with the strict standards set by our founder, Stan Roller.  Our founder established the Single-Number MTC Rating and has a true passion and knowledge for the cutting-edge concepts used in sound isolation.  We believe this is an important and often overlooked branch of Acoustics.  Understanding sound isolation is essential in a world that is becoming ever more conscious of its environmental impact.  Our consultants have extensive resources as well as an acoustic library with immediate access to almost all acoustic data and test results dating back to the earliest times in our field.  We have an unparalleled ability to assess and determine the necessity for sound isolation and identify the practical solutions for almost any noise control issue.
