Welcome to the next generation in hearing aid testing!
The FONIX 8000 is the world’s most advanced hearing aid test system, featuring the unique Polar Plot Sound Chamber, capable of performing automatic polar plot measurements of directional hearing aids. Although the results are not a replacement for laboratory testing using an anechoic chamber, the 8120 Polar Plot chamber provides the hearing health professional with a clinical tool for verifying approximate directionality characteristics of the hearing aid. As directional hearing aids continue to grow in popularity, this feature has become essential in the modern hearing aid clinic.
Directional Testing
The Polar Plot Option on the FONIX 8000 Hearing Aid Test System includes two test screens for performing measurements on directional hearing aids: The Directional Polar Test Screen and the Directional Difference Test Screen.The revolutionary Polar Plot test screen gives the clinician a 360º view of the directionality of the hearing aid at the specified angles. The two-dimensional directionality index (2D/DI) is automatically calculated for each curve as well as the overall average 2D/DI for all eleven possible curves. These values will help the clinician quantify the directionality of the hearing aid.
