NTi Audio Provides Professional Verification of Voice Evacuation Systems

Voice evacuation systems can save lives in an emergency. The correct installation and periodic functional testing of such systems are therefore essential. The NTi Audio TalkBox and XL2 Sound Level Meter with the new extended background noise correction are instruments designed for this purpose.

Audio Precision announced the introduction of their Speech Transmission Index (STI) plug-in for APx500 audio test software. Created for engineers developing public safety (police, fire, emergency) communications and public address systems, as well as flight recorder devices, the APx STI plug-in provides measurement capabilities conforming to international standard IEC 60268-16 (2011).
