Oconomowoc, WI, April 24, 2007: -Have you ever been in a facility when an announcement comes over the PA system and you can't understand the message? Voice communication and alarm systems play an important role alerting occupants and the clarity of that message can contribute to safe evacuation procedures.
Many things can affect the clarity of speech through a Mass Notification System. The National Fire Alarm Code (NFPA 72) specifies that voice alarm systems should meet specific levels of speech intelligibility.
Quest Technologies has now introduced two products for the evaluation and certification of Speech Intelligibility thru fire alarm, mass notification, and other PA systems. "The Verifier" is available as a stand alone Speech Intelligibility Meter and the Quest SoundPro® Integrating Sound Level Meter Models SE and DL feature the ability to measure and report Speech Intelligibility in STI-PA and CIS formats. They also feature a digital read out to take the guesswork out of whether you are in compliance or not.
Acoustic Spectral Curves are also included with the Speech Intelligibility package on the SoundPro® Models SE & DL. Acoustic Spectral Curves are a way to evaluate the quality of noise in new and existing buildings. The Sound curve options support captured curves, NC curves, PNC curves, NCB curves, NR curves and RC curves.
