Have it your way

We all strive towards a common goal: To achieve reliable test results to screen or diagnose patients accurately and efficiently.

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.

Making complicated things easy

A range of pre-loaded test protocols are available in each software module ensuring that you will quickly feel confident. After getting acquainted with the software you can add or modify test protocols and tailor them to your specific needs.

The clear layouts allow you to easily interpret the results and focus on the essential outcomes of the test, which can be saved into OtoAccess® Database for easy retrieval, review and export to your EMR in XML format.

Auditory evoked potentials

Knowing when to stop

Reducing noise is the single most important factor for improving any evoked potential recording. The residual noise calculator provides you with the knowledge of when to stop averaging, often saving test time and ensuring confidence in response identification.

Save valuable time

Using Bayesian Weighting during your ABR recording ensures that waveforms remain stable even during periods of patient activity. The influence of patient noise is minimized during the recording, resulting in continuously lower noise in the running average, saving valuable test time.

Fmp – improving confidence

Imagine having an objective waveform confidence indicator to assist you in confirming the presence or absence of a response. The Fmp graph provides objective and mathematical information based on multiple points within the recording to assist with your waveform analysis. Use of the Fmp provides a reduction in test time and confidence in your diagnosis.

Double your response amplitudes

The revolutionary CE-Chirp® stimulus family for threshold assessment (developed by Claus Elberling) compensates for frequency specific cochlear travel times and generates waveform responses up to twice the size of traditional click or tone burst stimuli.

The original CE-Chirp® was designed for optimal response amplitude at medium stimulation intensities. By using the level specific CE-Chirp®, clearer waveform morphology at high intensities is also available. The introduction of the CE-Chirp® LS stimulus family is an overall improvement to the original CE-Chirp® stimulus family.

For an easier visual evaluation of the NB CE-Chirp® responses, each of the NB CE-Chirp® stimuli have been time shifted to provide latencies similar to Click and the CE-Chirp® LS stimulus. The time-shifted NB CE-Chirp® are named NB CE-Chirp® LS, as the placements are level specific. Otherwise, the NB CE-Chirp® LS are identical to the original NB CE-Chirp®.

The CE-Chirp® stimulus family is incorporated in the EP25 (*optional for EP15) and ASSR software modules from Interacoustics.

CE-Chirp® stimulus family - the gold standard for threshold assessment

"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."

Aided Cortical module:
Aided benefit made clear

Traditional hearing testing is not possible in infants and in patients with complex needs, leaving a big question mark on the benefit of a fitted hearing device. Until now.

The Aided Cortical module for the Eclipse offers an objective method to validate the benefit of a fitted hearing aid or cochlear implant in patients who cannot subjectively respond to a hearing test.

In the background, there is a free field setup with one speaker. About a meter and a half away from the speaker, a parent is sitting in a chair with their infant child on their lap. The infant has electrodes placed on their high forehead and cheeks.

Speech-like stimuli

The aided cortical test is based on electrophysiological cortical responses and will allow you to evaluate whether the patient perceives speech-like sounds.

With the speech-like ManU-IRU stimuli and precise response detector, you get a quick and accurate tool that provides the control you need to make the right clinical decisions.

The included sound field analysis feature allows you to quickly check your sound environment and adjust the stimulus presentation accordingly.

Reassuring

You can use the aided cortical test to reassure parents or other relatives that the patient benefits from the hearing device and make informed adjustments to the hearing device if needed.

Enhance your patient's quality of life

By performing aided cortical testing, you can optimize the hearing care pathway and improve the outcome for infants and patients with complex needs who have a hearing loss.

ASSR: 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.

Multi-frequency testing

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.

Optimize VEMP through visual feedback

Vestibular investigation

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 confident and reliable result.

High output stimuli

The Eclipse VEMP (and ABR) can stimulate up to 100 dB nHL with clicks and 110 dB nHL with 250-4000 Hz tonebursts. The B81 bone conductor can go up to 75 dB nHL with 250-4000 Hz tonebursts.
