• Our Story

      Acentech’s origins and history began with the pioneering work of Bolt Beranek and Newman (BBN),founders of the acoustics and audiovisual profession.

      BBN built its reputation working on prestigious and high-profile projects in the United States, and grew into a world-class acoustical consulting firm serving clients globally. Among other technologies, practices and patents, BBN pioneered the use of computer models to design noise barriers near highways and airports, and designed acoustics for the most renowned concert halls and performance spaces in the world.

      In 1984, BBN and its pioneering acoustical consultants – who would later launch Acentech – were privileged to receive the American Institute of Architects (AIA) Institute of Honor Award, in recognition of “having almost single-handedly invented an entire profession by creating an awareness of acoustical considerations in design and by integrating solutions based on scientific principles with architectural and artistic concepts.”When the acoustics division of BBN became Acentech in 1989, we committed ourselves to building upon this rich heritage by serving a diverse group of global clients with robust technical knowledge and experience. Acentech is proud to be the only acoustical company incorporated directly from acoustics pioneer BBN. Many of our consultants have worked together at both BBN and Acentech, providing an outstanding continuity of service for 30+ years.

      Today, Acentech is a nationally recognized acoustics, audiovisual, IT and security system design, and vibration consulting firm with offices in Cambridge, Massachusetts, Philadelphia, Pennsylvania, and Los Angeles, California. With a professional staff of 50 consultants, Acentech brings more than 60 years of extensive experience and technical knowledge to projects, with an integrated approach that results in cost-efficient solutions and streamlined execution.
