Calibrated sounder for acoustic testings - TalkBox
TalkBox is an acoustic signal generator for speech intelligibility measurements in evacuation and announcement systems. It allows performing the complete end-to-end evaluation of the speech intelligibility STIPA from the talker’s microphone to the listener’s ears. It simulates a human talker (60 dBA @ 1 m) with the STIPA test signal and spoken messages.These provide a wide range of test signals like sine, pink noise, white noise and delay.It has a human head-like dimensions on a solid-state-generator. It replays the STIPA test signal at equalized frequency response, also ensures the most best performance through the internal amplifier and the precision loudspeaker.
