ASSR System


GSI AUDERA

The GSI Audera meets all your needs for Evoked Potential testing by providing a unique combination of Auditory Steady State Response (ASSR) testing and traditional auditory potentials (ABR, ECochG, AMLR and CAEP).

FREQUENCY-SPECIFIC HEARING ASSESSMENT

THE DEMAND

Universal newborn hearing screening using OAE and ABR technology is expanding globally. The result is that more infants require diagnostic follow-up testing. Consequently, there is a greater demand for accurate and frequency-specific hearing assessment of these infants. In addition, there are applications in older children and adults for frequency-specific objective testing.

THE SOLUTION

Auditory Steady-State Response (ASSR) is the solution for frequency-specific hearing assessment for people of all ages. Also called the steady-state auditory evoked potential (SSEP), ASSR meets all the criteria for follow-up diagnostic testing.

AUDITORY STEADY-STATE RESPONSE

• Can be reliably recorded in sleeping neonates, children and adults

• Are evoked by frequency specific tonal stimuli

• Can be detected objectively using statistical algorithms

• Have thresholds that are highly correlated with behavioral audiogram thresholds

Auditory Steady-State Responses

Obtain frequency-specific ASSR results and an estimated audiograrn using GSI Audera’s testing features. Designed with the user in mind, these features have been refined in more than 10 years of clinical use.

DELIVERING AFP, ASSR AND OAF AEP SOFTWARE FEATURES:

• Click, tone pip and tone burst stimuli with contralateral masking available

• No predefined limits on number of waveforms displayed • Multiple panels of waveforms displayed simultaneously • Continuous live display of ongoing input signals

• Display results for different tests, recorded with different time bases, in a single chart

• Unlimited number of user-defined test protocols

• Built-in, one-button electrode impedance measurement

• Data collected with different protocols can be displayed in the same chart or different charts

• User-definable marker/measurement tables

OAE SOFTWARE FEATURES:

• All DPOAE information is shown in a single display, including the FFT

• IOgrams provide input-output function analysis

• Automatic scoring available for DPOAE

• Spontaneous OAE functionality included

• Easy upgrades for existing GSI Audera systems with software and probe

Auditory Evoked Potentials Use GSI Audera to assess both cochlear and retro-cochlear function with these additional AEP testing capabilities:

ASSR SOFTWARE FEATURES:

• Clinically-validated protocols – University of Melbourne

• All ASSR information is shown in a single display

• Continuous live display allows easy monitor of ongoing EEG signals

• Electrode attachment integrity can be assessed with one-button, on-screen impedance measurement

• Evoke the ASSR with AM/FM-modulated tonal stimuli for the 250-8kHz frequency range

• Objective ASSR detection using patented algorithms eliminates tester subjectivity and provides quality control

• ASSR thresholds can be measured to 5dB accuracy

• The behavioral audiogram is estimated using patented algorithms, and a confidence interval is calculated for each threshold

• With one click of a button, quickly change between displaying individual trial results, ASSR threshold plots, and estimated audiograms

• Preview reports on screen and print them in full-size, single-page format in black and white or color

It is now recognized that early intervention is critical to speech and language development in hearing-impaired infants and children. Available interventions include fitting a hearing aid before six months or performing a

cochlear implant as early as one year of age. Selection of the proper plan requires accurate, detailed information about the hearing loss at all frequencies important for speech and language development.

This makes it critical that hearing clinicians have an objective, reliable method for measuring frequency-specific hearing thresholds in neonates and infants with mild to profound hearing losses. While various technologies including OAE, ABR, and visual reinforcement audiometry have been used, their limitations prevent them from fully meeting the need.

Otoacoustic Emissions

With its combination of reliable DP technology, user-friendly graphic interface and easy-to-understand results, the GSI Audera DPOAE is the instrument for otoacoustic emissions testing in hospitals, clinics and offices around the world.

Audiotory Evoked Potentials

Use GSI Audera to assess both cochlear and retri-cochlear function with these additional SEP testing capabilities:

• Electrocochleography (ECochG)

• Auditory Brainstem Responses (ABR)

• Auditory Middle Latency Responses (AMLR)

• Long Latency or Cortical Responses (LLR)

• Electrical ABR

FEATURES
