NTi Audio TalkBox
The NTi Audio TalkBox is required for the verification of installations where voice microphones are in use. The TalkBox produces a calibrated, acoustic, speech-intelligibility test signal that is picked up by the operator’s microphone. The TalkBox simulates a human talker in accordance with the IEC 60268-16 standard, thereby including the microphone and the acoustic environment of the operator’s location in the test. The entire signal path is thus tested, providing a complete STIPA speech intelligibility measurement.
The TalkBox provides two major advantages for STIPA measurements:
- An extended test coverage and an easy to handle test signal injection.
- Sampling frequency deviations - a dangerous trap when using portable CD players - are completely eliminated.
The Minirator MR-PRO is used for electrical signal injection into public address systems that commonly use alarm messages from a hard drive (systems without a microphone).
