Cavanaugh Tocci Associates

What Cavanaugh Tocci Associates does

Cavanaugh Tocci Associates, founded in 1975 by Bill Cavanaugh and Greg Tocci, is a private acoustics, audiovisual, and theater consulting firm headquartered at 327 F Boston Post Road in Sudbury, Massachusetts, approximately 20 miles west of Boston. The firm operates with 17 full-time consultants holding advanced degrees in acoustics, mechanical and electrical engineering, physics, architecture, theater, and music, and has completed more than 15,000 projects across its history, including dedicated environmental acoustics work on over 300 warehouse and distribution facilities.

The firm is organized around four practice areas: Architectural Acoustics (sound isolation, room acoustics, HVAC noise control, vibration isolation); Environmental Acoustics (ISO 9613-compliant computer noise modeling with GIS integration, regulatory review, and peer review); Audiovisual Design (sound and video systems using Revit, CAD, and loudspeaker modeling); and Theater Consulting (venue design, seating, lighting, rigging, machinery, contract documents, and acceptance testing). Core tools include the ISO 9613-compliant Cadna/A modeling environment, Revit and CAD, loudspeaker modeling software, and GIS-integrated analysis for noise prediction at receptors incorporating topography, barriers, and zoning layers. The firm maintains an active publication record, including co-authored textbooks such as 'Architectural Acoustics—Principles and Practice' and 'Halls for Music Performance,' and contributes to ANSI standards for speech privacy and room criteria.

Revenue is generated through project-based professional services engagements priced by scope rather than disclosed unit pricing. Distribution is exclusively direct: the firm engages architects, engineers, developers, institutional owners, government entities, and municipalities through proposal writing, scoping, and project lifecycle work from schematic design through commissioning, and participates in permitting processes as an expert witness. Customers span higher education (Harvard, Yale, Dartmouth, Brown, Cornell, Northeastern, University of Rochester, Boston Arts Academy), K-12 (Saugus, Chapman, Mount Ararat, Arlington, Phillips Academy), performance venues (Roadrunner Boston, The United Theater, Ventura Music Hall), sports facilities (The Track at New Balance, Cornell and Brown recreation centers), industrial and logistics clients, energy facilities across New England, and hospitality (Weekapaug Inn, Lawson's Finest Liquids). Marketing channels are limited to a project portfolio on the firm's website, professional society participation (ASA, INCE, AES, NCAC, USITT), public meeting presentations, and referral networks within the A/E/C community. Leadership is transitioning in 2026 with Alex Bagnall appointed Managing Director, following Tim Foulkes's retirement in 2025 and the conclusion of Douglas Bell's presidency (2014-2025).
