  • 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).

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.

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.
