Products with this attribute (1 total)

The NTI <b>TalkBox</b> 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.</p><p>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.</p><p>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.</p><p>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.</p><p><b>Applications for TalkBox:</b><br />Evacuation Systems <br />Installed Sound<br />AV-Installations</p>
