Grason-Stadler Audera

Audera meets your needs for Evoked Potential testing by providing a unique combination of Auditory Steady State Response (ASSR) testing and traditional cochlear and retro-cochlear auditory potentials (ABR, ECochG, AMLR and CAEP). 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. GSI Audera also provides DPOAE testing for hospitals, clinics and offices.

Interacoustics Eclipse

Eclipse is the Interacoustics platform for measuring auditory evoked potentials and otoacoustic emissions. It is a single high performance hardware unit controlled from a laptop or PC by a variety of software modules designed around specific test areas.

Vivosonic Integrity™

Using Kalman Weighted Filtering, the Integrity is able to generate superior diagnostic results without sedation. This is particularly suitable to pediatric patients, who can now feed, speak, play or wake up while being tested. It is also an invaluable tool for-hard-to test patients from the general population.

​The first system to possess wireless capabilities, Integrity is a revolution in portable diagnostics, fitting unobtrusively on an alert child’s back who is playing quietly during testing, or into the OR. In addition, the Amplitrode (a miniature electrode mounted bio-amplifier) protects against electromagnetic noise, delivering clear results in places with electric and magnetic interferences such as Neonatal Intensive Care Units (NICU), hospitals, military medical centers, Operating Rooms (OR) and other clinical settings
