  • Solid and noise immune hardware
  • Modular and future-safe platform
  • Unique pre-amplifier technology
  • Well-designed layouts and freedom to customize settings
NEW Explore IA OAE suite for the Eclipse.

Design your own diagnostic solution

Whatever your challenge may be, the Eclipse hardware platform enables you to focus on the job at hand with the assistance of dedicated software modules for all facets of auditory evoked potentials and otoacoustic emissions.

„The Eclipse has the largest number of clinically-relevant features of any AEP device today. The platform is an excellent blend of parameter flexibility and user-friendliness.“

The Interacoustics ASSR system reduces test times by 50% thanks to Narrow Band CE-Chirp® stimuli and new powerful automated dual response detection methods.
  • 8 frequencies to be tested simultaneously to threshold in less than 20-30 minutes
  • Save data directly to NOAH

EP25 - Clinical ABR

  • Includes all the features of EP15
  • AMLR, ALLR & P300/MMN testing
  • ECochG Area Ratio Calculation by John Ferraro
  • Research module
  • CM & ECochG testing (optional for EP15)
  • CE-Chirp®, NB CE-Chirp®, CE-Chirp® LS & NB CE-Chirp® LS for optimized threshold assessment (optional for EP15)

New IA OAE Suite

The next generation of OAE software comes with either DPOAE, TEOAE or both and offers a lot of advantages compared to previous OAE software.
  • A whole new user interface
  • Probe check indicator (in/out of ear)
  • Split screen (left and right)
  • Test summary table (incl. SNR and reliability)
  • Historic overlay (compare test data)
  • Prolong tests and add more sweeps
  • Protocol settings for automatic display of pass/refer results for hearing screening
  • Weighted averaging improving data quality and limiting the test time
  • DPOAE frequency range 500-10000 Hz
  • TEOAE frequency range 500-5500 Hz

DPOAE - Distortion product emissions

The DPOAE module produces detailed DP Grams with protocols designed by the user for their preferences or requirements. Confidence in the OAE measurements is ensured via DPOAE reliability criteria.

TEOAE - Transient evoked emissions

The TEOAE uses non-linear broad band clicks to evoke otoacoustic emissions. The extensive range of clinical options provide a full clinical evaluation of TEOAEs.

Optimize VEMP through visual feedback

The Eclipse oVEMP and cVEMP tests measure and analyse the vestibular evoked myogenic potential generated by a loud stimulus.
  • Instant visual feedback – increased quality
  • EMG-based scaling - a reliable result
  • Stimulate up to 100dB nHL with clicks and 110dB nHL with 250Hz-4kHz tonebursts
  • The B81 bone conductor can go up to 75dB nHL with 250Hz-4kHz tonebursts
  • Research module option

The research module

Export waveforms

With the click of a mouse, select the recording to be exported in its averaged state, as presented on the screen. The exported waveform or session is saved in a XML le on the hard drive. The XML- le can be viewed in Microsoft® Excel, MATLAB® or similar analysis software.

The export waveform/session function is available on saved recordings that are created on an Eclipse with the Research Module license, even when viewed on another PC. This gives the exibility to collect data in one location and analyse in another without the need for a connection to the Eclipse.

Import wavefiles

The Research Module allows you to import WAV les, which can be used as stimuli in any ABR test.

  • Add a speech sound for cortical testing
  • The speech stimuli, Da, Ba and Ga are included for any ABR or MMN test
  • Custom WAV file stimuli can be calibrated and a peRETSPL - nHL correction value can be specified, as with traditional stimuli
  • Combine two different WAV files to create an alternating polarity stimulus
  • A WAV file can be specified as a continuous stimuli and used as masking noise

Data logging

The data logging function allows all sweeps to be saved (logged), permitting the entire recording to be “replayed” in analysis software such as Microsoft® Excel or MATLAB®. From here, multiple test parameters can be modi ed (e.g., change the ltering or apply weighed averaging in a replay of all the sweeps) and the resulting waveform reassessed.

The logging can be applied to both custom research protocols or the standard default protocols. The logged sweeps are saved in three text les on the hard-drive.

Optional Eclipse Cart

The optional Eclipse cart offers great mobility and organized storing.

1. The CE-Chirp® stimulus family was developed following many years of extensive human studies by numerous researchers including Claus Elberling, the researcher who the CE-Chirp® has been named in honor of.
2. The Research Module license provides a new dimension in the investigation of AEP recordings. Easily added to your existing EP25 software (from version 4.4) with a new license key.
Note: For countries where the IA OAE Suite has not been registered with the authorities, the previous OAE software will still be available.
