Instrumen OAE, BERA / ABR, ASSR merek GSI - Grason Stadler Type Audera Made in USA

Features

GSI Audera Main Unit

• Separate output jacks for left, right and bone transducers, and a free-field speaker output eliminates time wasted switching between transducers
• Built-in mains isolation transformer for safety provides isolated power for a notebook computer and an inkjet printer
• Standard USB interface connects to virtually all of the latest computers
• High-speed serial interface connects to the GSI Audera digital amplifier subsystem

GSI Audera Digital Amplifier Subsystem

• Small size and weight facilitates convenient placement near the patient
• Full two-channel capability for ispilateral/contralateral ABR recordings Isolation for patient safety
• Digital connection to main unit minimizes interference from external noise sources
• Built-in impedance measurement with LED readout at the amplifier minimizes preparation time

GSI Audera OAE Probe

• Superior probe design for neonatal to adult testing
• LED indicates test status
• Backward compatible with all GSI Audera systems

GSI Audera is Compatible With Most Personal Computers

• 32-bit application software operates in several versions of Windows
• Operates with display resolution of 1024 x 768 or higher
• Uses standard Windows drivers for printing on the device of your choice
• Patient database can be backed up on most Windowscompatible archiving devices

GSI Audera’s Standard TIP-50 Insert Transducers

• Foam tips of various sizes eliminate the problem of collapsing ear canals
• Soft 2.5 and 3 mm tips included for tiny infant canals
• Silicone tubes create an acoustic delay, minimizing the click stimulus artifact in ABR recordings
• Stimuli are calibrated in dB HL for ASSR testing and in dB nHL for AEP — calibration data is provided for each transducer set

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.
