NTi Audio TalkBox
The NTi Audio TalkBox is required for audio systems with voice microphones. The TalkBox feeds the test signal into the operator microphone of sound reinforcement systems. It presents the standardized voice-like acoustic signal emission simulating a human talker according to IEC 60268-16, combined with a TNO certified speech intelligibility signal at standardized levels. This setup considers the entire signal path for an accurate STIPA measurement. It includes all effects of the operator's microphone and environment.
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).
