Our firm provides consulting and design services for clients interested in audiovisual systems for their facilities. A collaborative team approach gives our clients the benefits of our collective experience. Typical audiovisual projects for Salter consultants include designing audio systems, teleconferencing and distance learning systems, sound masking, multimedia web content engineering, and network operations command and control centers. We design audio and video systems for use in businesses, theaters, hospitals, educational campuses, worship spaces, and private residences. Now more than ever before, these elements have become a necessity for everyday interactions and communication.

Architects, building owners, and facilities managers are faced with complex and costly issues when considering audiovisual systems for their projects. Salter provides consulting and design services; we do not sell, manufacture, or install equipment and have no alliance with any brand. Therefore, recommendations are made solely with our clients' interests in mind.


Audio system design is a multi-disciplinary practice that includes electrical engineering, acoustics, building construction, and human factors. These systems are used for speech reinforcement, teleconferencing, live music, and media playback. The goal for an audio system designer is to provide high-quality, intelligible sound to every seat in the house. To achieve this goal, the designer needs to consider many related factors including room acoustics, architectural and aesthetic considerations, sight-lines, and ease of use for the operator. The end result will be systems that provide full-spectrum response, clarity, and intelligibility with no feedback. Building types that often require audio systems include educational facilities, theaters, conference centers, boardrooms, residences, hospitals, and worship spaces.

Projection + Display

Design for audiovisual projection and display systems is a practice that considers the viewer, technology, architecture, and lighting within the space. The designer must be versed in the many available technologies, aspect ratios, pixel densities, and display brightness capabilities if displays are to provide images with good contrast, color rendition, and legibility of text. Conference rooms, boardrooms, auditoriums, courtrooms, operation centers, distance learning classrooms, and cinema venues all have projection and display considerations.

Video + Broadcast

Video and broadcast systems are found in more environments than ever before. Low-cost, high-definition television (HDTV) cameras and other traditional broadcast studio equipment have brought this technology to high schools, colleges, and places of worship. High definition video systems are often integrated with audiovisual presentation or distance learning systems and require the audiovisual consultant to know current broadcast technology practices. Other venues that integrate digital video technology as a part of an audiovisual system include city council chambers and corporations where it is used in support of video conferencing as well as recording.

Digital Signage

Digital signage is the application of flat-panel video displays for presenting information, advertising, messaging, and “way-finding” in public spaces. Unlike traditional building signage, the information on digital signage can be readily updated and can include real-time display of dynamic media such as weather, stocks, traffic conditions, and other evolving information. The digital signage designer must understand the data handling capabilities of the many digital signage solutions to meet the signage owner's ability to create, manage, and update content. Our designers also understand factors affecting the viewability of signage displays, including ambient lighting, display size, viewer distance, and sight lines. Lobbies, reception areas, libraries, circulation spaces, and retail are just a few of the places where digital signage can be found.

Sound Masking

Sound masking systems add electronically generated noise to an environment to improve speech privacy and cover up unwanted sound. The sound masking system designer must account for the principles of acoustics, electro-acoustics, and human perception, since poorly designed and implemented systems can create as many problems as they solve. When properly implemented in an office environment, sound masking can reduce the awareness of unwanted sounds, making a work environment more comfortable, while also improving speech privacy so that workers can better concentrate and be more productive. Open plan offices, medical lobbies, patient consulting areas, detention centers, conference rooms, and other areas where speech privacy is an issue can benefit from reliable sound masking systems.


Videoconferencing, audio teleconferencing, distance learning, and telepresence are the types of systems that facilitate effective communication between people in distant places. These systems reduce the need for travel and are perhaps the "greenest" of building systems. The conferencing system designer must understand acoustics, lighting, audiovisual, and Internet-based communication networks. The conferencing system should provide audio with excellent intelligibility, free from echo, reverberation, feedback, and distortion. For videoconferencing, distance learning, or telepresence systems, images should be clear, with properly lit participants, and should provide full motion video quality with minimum of compression artifacts and latency. Conferencing systems should also allow for the free exchange and interaction of data and graphics from laptops and other computers between the distant sites. Facilities that include conferencing systems include business offices, universities, hotels, research, and conferencing centers.
