A S und Investment audio is given consideration before the walls go up. In years past, Emlinger says that number was more like 50 percent. “Once the walls are covered up, if no thought has been given to audio, then running the necessary cables can be very difficult,” he adds. Joe Keefe from Ostergaard Acoustical Associates agrees that decisions about sound systems come up at various points, perhaps multiple times, throughout a project. Keefe recommends that audio system design consultants provide input into whether an audio system should be a part of a project, relying on their expertise to help make the correct choices. Silverman’s Learning Space Design Team of three at GMU manages audio and other technology solutions. The team pulls in other IT colleagues to ensure that specifications are correct, products are researched and agreed upon, and everything works across systems. Since GMU pulled these disciplines in-house six years ago, the university does not use consultants. Johns Hopkins’ Murphy meets frequently and informally with the director of campus operations to discuss changes or additions to its audio system. Murphy ultimately makes the final decision. Can You Hear Me? Coverage and intelligibility are topics that come up during the details of installations, says von Kries. Unfortunately, many hornbased alarm and paging systems tend to sacrifice intelligibility and coverage area for efficiency and maximizing the sound pressure levels of the system. If a speaker does not provide adequate coverage across the whole campus with wide dispersion speakers, von Kries says there is the risk of holes within the coverage area. The most common factors that George Mason University faces relating to audio clarity and quality are high levels of ambient Equipped for teaching: Typical small, yet central, classrooms at UC Boulder have a projector and control system, an audio amplifier, and an input panel, the total cost of which is about $4,000 per room. sound and poor speaker placement. “Our in-house design team has worked closely with our facilities group to minimize HVAC and other mechanical noise, as well as provide as much sound isolation to classroom spaces as practical,” Silverman says. “As for speaker placement, this can easily be overcome by doing speaker coverage studies ahead of time and then following the speaker plan at install.” Silverman suggests that campus administrators have welldefined requirements prior to starting their designs, as they consider updating or adding new audio systems. This involves simply investing the time in design and studies ahead of the project. “Simple audio calculations on whether you will have proper coverage and reinforcement on the front end,” he notes, “will save you a lot of grief on the backend.” Vicki Powers is a Houston-based freelance writer.
