GSI Corti™, a new hand-held OAE instrument


Grason-Stadler (GSI), a world leader in audiometric assessment instrumentation, introduces the GSI Corti™, a new hand-held Otoacoustic Emission (OAE) instrument for screening and diagnostic testing. The Corti provides both Distortion Product Otoacoustic Emissions (DPOAE) and Transient Evoked Otoacoustic Emissions (TEOAE) in a battery powered instrument. The Corti is designed for fast paced screening and diagnostic clinical environments for testing patients of all ages, infant through adult.The intuitive color OLED display on the Corti provides color graphics that are easy to interpret. Assessment may be completed in two ears in as little as three button presses. The four-button operation is easy to learn and use. The Corti introduces smart technology that maximizes accuracy and speed. Corti’s Auto Start automatically assesses the probe fit, background noise and probe stability. When conditions are acceptable, in-the-ear calibration is conducted providing stimulus precision. Immediately following the Auto Start routine, the testing automatically initiates. During testing, Corti continually assesses the probe fit and background noise to ensure test results are accurate. The patented Adaptive Noise Algorithm which uniquely identifies and manages the emissions in challenging variable noise conditions is pivotal to Corti’s speed and accuracy.

Using either DPOAE or TEOAE, the Corti provides fast, accurate screening with results acquired in seconds, and includes data compatibility to HiTrack and OZ eSP which may be a requirement for reporting newborn-screening data. Corti DPOAE and TEOAE protocols are designed to meet U.S. CPT code requirements for a fast return on investment.
