    600 000 085 - Overview

    The TalkBox is an active acoustic signal generator for speech intelligibility measurements in evacuation and announcement systems, as well as for level alignment of teleconference or any audio system incorporating a microphone input. It allows performing 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 meter according to IEC 60268-16) with the STIPA test signal and spoken messages. Further it provides a wide range of test signals like sine, pink noise, white noise and delay.

    The TalkBox features human head-like dimensions and is based on a solid-state-generator. It replays the STIPA test signal with a precise frequency response, individually equalized for each TalkBox, also ensuring best performance through the internal amplifier and the precision loudspeaker. A variety of supplied or user-defined test signals may be precisely output for different alignment applications.

    Designed to the latest quality standards for reliable measurements results. It offers unmatched signal purity with a distortion lower than 1% over the complete frequency range from 100 Hz to 10 kHz. This ensures the repeatable and precise verification of the speech intelligibility STI.
