SynAudCon Presenting Emergency Communication Systems (ECS) Speech Intelligibility Workshop

SynAudCon will be presenting the Emergency Communication Systems (ECS) Speech Intelligibility Workshop this coming January 3-5 (2013) at the American Airlines Training and Conference Center in Dallas.

With the new NFPA-72 and UL2572 codes that are associated with Emergency Communication Systems, speech intelligibility seems to be on everyone’s mind.

The ECS Speech Intelligibility Workshop will:

—Foster the design of intelligible systems

—Bring attendees up to speed on the codes

—Teach the measurement process to instill confidence that every system will meet the codes

The American Airlines Training and Conference Center, pictured below, is an ideal venue for the workshop. It offers a mock-up of Chicago’s O’Hare Airport terminal, complete with a reverberant field, arch ceilings, large windows—all of the problems that plague large spaces.

SynAudCon has assembled an all-star staff with expertise in system design, intelligibility codes, and STI theory and application, to lead the workshop.
