Products GSI Audera

Overview

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.

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.

"and now the ASSR solution is available in a clinical instrument -- the GSI Audera"

The GSI Audera is available in portable or desktop versions to allow you to use the GSI Audera in multiple locations or at bedside.

 

Features

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.


 

ASSR - Auditory Steady-State Response

Obtain frequency-specific ASSR results and an estimated audiogram 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.


 

AEP - Auditory Evoked Potentials

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

  • Electrocochleography (ECochG)
  • Auditory Brainstem Responses (ABR)
  • Auditory Middle Latency Responses (AMLR)
  • Long Latency or Cortical Responses (CAEP)
  • Electrical ABR

 

OAE - 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.
