Communications in Collaborative Spaces (HSW)

More and more clients are requesting the collaborative spaces from designers. This includes both collaborating with each other within the same room, and collaborating with peers across the globe. Sometimes this is a flexible-use space that allows users to mobilize and have group discussions, and other times it is more of a lecture-style space that must also accommodate for group discussions from the audience. These rooms not only have technology requirements to house, but also have acoustic challenges that need to be addressed in order to make these rooms successful. Acoustics, noise control, room size/shape, and thoughtful AV design greatly enhance the professors’, students’, and distant learners’ experiences and, in many instances, make the difference between a favored room and an unused room. We will describe what those requirements and challenges are and give you some tools to help create a space your clients will enjoy using. Numerous project examples will be shown, along with demonstrations of online collaboration tools.

NFPA 72 Mass Notification Regulations

The National Fire Protection Association mandates that within public acoustically distinguishable spaces (ADS) where voice communication systems are required, the system can reproduce pre-recorded, synthesized, or live messages with voice intelligibility. Meeting NFPA’s criteria requires careful design, especially for facilities with acoustically dissimilar spaces, like mass transit, healthcare, higher education, and convention centers. A case study describes the process of achieving voice intelligibility in ADS from preliminary design to final testing.

NFPA 72 Fire Alarm Code: Mass Notification System Design Overview

With the release of NFPA 72-2010, opportunities for mass notification technology have increased. Today, alarm and mass notification systems must provide threat-specific verbal guidance and instruction for a variety of threats and hazards, not only within a building, but also outdoors (across a campus for example). Learn about the main components of a mass notification system: identifying acoustically distinguishable spaces, audio system and data network design including fault-tolerance, redundancy and survivability, high-power speaker areas and voice intelligibility testing.
