FIRM PROFILE

CHARLES M. SALTER ASSOCIATES, INC., consultants in acoustics and audio/visual system design, was founded in 1975. With a staff of 31, we are involved in more than 600 projects per year in seven major service areas:

• Architectural Acoustics: designing room acoustics, sound isolation, and noise control for performing arts centers, audio recording, production/post-production facilities, and broadcast studios; government/educational/cultural facilities; airports; housing and hotels; office buildings; hospitals; research facilities; and places of worship.

• Engineering Acoustics: reducing noise and vibration from mechanical, ventilation, plumbing, and transportation systems; product noise control; and acoustic modeling.

• Environmental Acoustics: assessing environmental noise impacts from various sources, including vehicular traffic, airports/heliports, buses, light rail and railroad facilities, construction, geothermal plants, mines/quarries, etc.; designing noise mitigation including sound rated windows, doors, and noise barriers.

• Audio/Visual System Design: defining audio/visual requirements for media rooms and presentation facilities; developing audio/visual design requirements into contract documents; testing the system's electrical, visual, and acoustical characteristics to document performance; and training system operating personnel.

• Sound System Design: integrating electroacoustical systems and architectural acoustics; electronically enhancing room acoustics; reinforcing music and speech in theaters, halls, arenas, shopping centers, meeting rooms, and boardrooms; and designing sound masking systems for offices; design and measurement for loudspeakers.

• Acoustic Simulation: calibrated aural simulation of acoustical environments, generally prior to construction, including sound isolation, reverberation and ventilation noise. Simulations are presented in a sound isolated studio using current multimedia technology.

• Public Presentation/Expert Testimony: effectively communicating technical information to decision-makers and the public at meetings and hearings; providing expert testimony as part of judicial proceedings.
