From screening ABR to specialized AEP

EP15, EP25 and ABRIS

The Eclipse is a modern and versatile platform. It is designed to fit seamlessly into your everyday work ow and to offer complete reliability and perfect results.

Fast and objective ABR screening

ABRIS is a fast screening software that can be used for all age groups. It returns a simple pass/refer result, requires minimal tester training and is automatic and objective.

Just click “START”

After attaching the electrodes and making a quick impedance check – simply click “Start” and you are set to go. EEG monitoring is provided with a continuous graphical display and no measurements are collected during periods of unacceptable noise. Results are clearly displayed in: Green for Pass and Red for Refer – it’s that easy!

99.7% – don’t settle for less

ABRIS specificity (the ability to correctly exclude normal hearing babies) is as high as 99.7% in large scale clinical trials using two stage screening. ABRIS sensitivity (the ability to correctly identify babies with hearing problems) is 99.99% based on large-scale simulations.

Diagnostic ABR

Developed for clinics performing standard threshold and neurological ABR testing, the EP15 will allow you to do a common task surprisingly well.

A new standard

The contemporary interface delivers unrivalled ease-of-use and superior clarity, which will help you achieve clear and reproducible results in a con dent and timely manner. Pre-loaded protocols peer-reviewed by key-experts, easy tailoring of manual and automatic test protocols and a multitude of useful tools make the Eclipse the preferred choice for threshold and neurological ABR.

For your daily routine

  • Threshold & neurological ABR testing & eABR
  • Bayesian weighting
  • Residual noise calculator
  • Fmp calculator
  • SNR 3:1 ratio calculator
  • CR, RA, INC waveform markers

Clinical AEP

For those who need specialized procedures requiring the full spectrum of AEPs: Go for the advanced EP25 software.

The benefits of specialized features

The EP25 contains all the useful features found in the EP15, but adds the extra functionality needed by more specialized clinics. The EP25 incorporates a full range of test protocols covering the early, middle and late latency tests.

EP25 features

  • All the features of EP15
  • AMLR, ALLR & P300/MMN testing
  • CM & ECochG testing
  • ECochG Area Ratio Calculation by John Ferraro
  • CE-Chirp®, NB CE-Chirp®, CE-Chirp® LS & NB CE-Chirp® LS for optimized threshold assessment
  • Research module including waveform export, logging of recordings, and importing WAV files for stimuli (optional)
Where speed meets accuracy


The Interacoustics ASSR system reduces test times by 50% thanks to Narrow Band CE-Chirp® stimuli and new powerful automated dual response detection methods.

A new (and faster) generation

Interacoustics ASSR represents a true breakthrough and a new generation in ASSR threshold estimation. The ASSR software enables 8 frequencies to be tested simultaneously to threshold in less than 20-30 minutes through the use of Narrow Band CE-Chirp® stimuli and a patented detection engine.

Full control – full speed

You will dramatically shorten test time as you are in full control of selecting the appropriate stimulus levels independently for each frequency based on current and previous results. Also, you are able to change the stimulation rate during testing depending on the state of your patient. All in all: Full control allows full agility and speed.

Cut test times in half

The Interacoustics ASSR software uses the Narrow Band CE-Chirp® stimuli to generate a maximal response, which makes the detection fast and efficient. The dual detection engine evaluates both the phase and the response magnitude from 12 of the higher harmonics of the fundamental modulation rate. This patented technology can reduce test time by 50% compared to traditional ASSR systems and offers unsurpassed accuracy.

Save data directly to NOAH

The estimated audiogram generated by the Interacoustics ASSR can be saved to NOAH. The estimated audiogram can easily be transferred to Genie or other similar hearing aid fitting software, ensuring a smooth and accurate hearing aid fitting.
Otoacoustic emissions


The Eclipse hardware platform accommodates both DPOAE & TEOAE capabilities.

Shared features and benefits

  • Lightweight probe with low internal noise
  • Easy to place in the ear
  • Inexpensive to maintain
  • Auto probe check determines correct placement
  • Validity checkmarks for OAE detection confirmation
  • User-controlled noise sensitivity and rejection for easier collection


Distortion product emissions

The DPOAE20 module produces detailed DP Grams with protocols designed by the user for their preferences or requirements. Build your own customized normative data sets or use the supplied norms from Interacoustics.

Transient evoked emissions

The TEOAE25 uses linear or non-linear broad band clicks to evoke otoacoustic emissions. The extensive range of clinical options provide a full clinical evaluation of TEOAEs. The TEOAE25 also has protocol settings for automatic display of a pass/refer result for hearing screening. Factory defaults are also available.
Optimize 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

Valid cVEMP results are dependent on correct and controlled EMG tonus. The VEMP software provides visual feedback of the muscle contraction to assist you in helping the patient to obtain correct muscle tonus throughout the entire test. This can be done from the software or on a separate patient monitor for cVEMP testing.

EMG-based scaling - a reliable result

By applying EMG-based scaling of the obtained waveforms, you are ensured a crucially important balanced presentation of responses from Left and Right – ensuring a con dent and reliable result.

High output stimuli

The Eclipse VEMP can stimulate up to 100dB nHL with clicks, 250Hz, 500Hz, 1kHz, 2kHz and 4kHz tone bursts.

Research module option

Research module including waveform export, logging of recordings and importing WAV les for stimuli (optional).
Optimize through visual VEMP feedback
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.
