Specifications

  • Patented ASSR technology that obtains objective frequencyspecific auditory threshold information
  • Simultaneous testing of up to 4 frequencies per ear2
  • View real-time EEG and the response spectrum
  • Easy monitoring of on going test results – tables and graphs on the collection screen clearly display the response amplitude and noise floor
  • Printing of physiological audiogram with air conduction, bone conduction and soundfield data on the same audiogram
  • User-defined stopping rules to automatically halt collection for individual frequencies based on the number of sweeps, noise levels, and/or statistical criterion (p-value) as well as the ability to stop individual frequency collections manually
  • Choice of montage using Cz to Nape or Cz to Mastoids
  • Masking is available for bone conduction or unilateral hearing loss3
  • Option for higher stimulus intensities (up to 119 dBHL) than available with standard AEP for threshold estimation in children and adults with profound hearing loss
