Auditory Evoked Potentials

AUDERA

EVOKED POTENTIALS SYSTEM

Hearing care professionals conduct an auditory evoked potentials test to determine how long it takes nerves in the auditory system to respond to sound and electrical stimuli. Grason-Stadler, a world leader in audiometric assessment instrumentation, provides a user-friendly, clinical solution that meets the testing needs of busy clinics and ENT practices.

The GSI Audera™ provides Auditory Evoked Potentials (AEP) and Auditory Steady-State Response (ASSR) testing in a modular system for busy audiology and ENT professionals. The Audera excels in generating high quality data, providing simple system operation, and utilizing convenient database management. Evoked potential results are easily interpreted through comparison to normative data sets. ASSR is the solution for accurate, frequency-specific hearing assessment for patients of all ages.

FEATURING CE-CHIRP

The GSI Audera is proud to feature the CE-Chirp® and CE-Chirp Octave Band stimuli. The technology optimizes the simultaneous firings along the basilar membrane resulting in larger Wave V amplitudes compared to traditional click and tone burst stimuli. Wave V generated by a CE-Chirp has been demonstrated to be 1.5 to 2 times larger in amplitude than Wave V generated by a click. Frequency-specific threshold testing results in reduced test time, less need for sedation, and increased test confidence for hearing care professionals, especially when testing infants and children.

LEARN MORE

ONE DATABASE

Reduce training time and increase the comfort level for audiologists by using the same operation for both testing modalities - Auditory Evoked Potentials and Auditory Steady State Response. By using a consistent user interface, short cut keys, and automated test sequencing, clinicians will quickly gain familiarity with the technology. Protect your data with a robust and flexible SQL database to archive, backup, and review all patient data.
SHAPE YOUR TESTING

Customize test protocols, ensuring a standardized methodology is used. Enhance clinical confidence of data interpretation when comparing results to published norms, or set your own normative data for specific research needs.
KEEPING THE FOCUS

Perform bedside electrode impedance checks instead of having to go back and forth to the computer. Save time and increase clinical confidence using CE-Chirp, CE-Chirp Octave Band stimuli with up to two times greater ABR amplitudes.

Key System Features

1. CUSTOMIZABLE PROTOCOLS

Save valuable time by using standard protocols or establish your own for specific testing situations.
2. CONTINUOUS DISPLAY

Continuous live display of waveform and EEG allow you to monitor the test.
3. NORMATIVE DATA

Normative data is provided for all test stimuli including CE-Chirp for adults and infants. Quickly establish and enter clinic normative data and waveform markers.

4. CONSISTENT USER INTERFACE

Reduce training time and increase comfort level among clinicians using the same software application for both test types.
5. CE-CHIRP AND CE-CHIRP OCTAVE BAND

Ideal test stimuli for collecting robust waveforms in the fastest amount of time.
6. ABR AMPLIFIER ELECTRODE IMPEDANCE MEASUREMENTS

Save time and make changes by checking electrode impedance at the patient's side instead of at the computer.
