Key Features

  • Software modules: EP15 (ABR, eABR), EP25 (ABR, eABR, MLR, LLR, P300, MMN, ECochG), ABRIS (automated ABR screening), ASSR (threshold assessment), Aided Cortical, cVEMP and oVEMP, DPOAE and TEOAE
  • EP15 provides threshold and neurological ABR and eABR, Bayesian weighting, residual noise calculator, Fmp calculator, SNR 3:1 ratio calculator and normative latency data
  • EP25 adds AMLR, ALLR and P300/MMN testing, CM and ECochG testing, and ECochG Area Ratio Calculation
  • Optional research module with waveform export, logging of recordings and import of WAV files for stimuli
  • ASSR software enables 8 frequencies to be tested simultaneously using Narrow Band CE-Chirp stimuli
  • ASSR estimated audiogram can be saved to NOAH
  • ABRIS returns a pass/refer result with continuous graphical EEG monitoring
  • Aided Cortical module uses speech-like ManU-IRU stimuli with the Fmpi response detector
  • OAE modules share a probe check indicator, historic overlay, test summary and weighted averaging
  • cVEMP and oVEMP with visual feedback of muscle contraction, EMG-based scaling and automated VEMP ratio calculation
