Calibrated sounder for acoustic testing
NTi Audio
NTi Audio TalkBox features human head-like dimensions and is based on a Solid-State-Generator with CF-Card. It perfectly equalizes the STI-PA test signal and replays it at the precisely correct playback sampling rate, also minimizing systematic errors through the internal amplifier and internal precision loudspeaker. Due to the required overall accuracy of ±1 dB over the relevant frequency range, each TalkBox is individually equalized and calibrated for precision output. The radiation characteristic complies with the ITU-T P.51 in wide ranges. The built-in combination of solid state generator and DSP ensures highest playback accuracy and lowest sample frequency deviations with minimized jitter effects.
