Threshold establishes the patient's ability to hear the lowest possible hearing level.
Earscan incorporates user selectable frequency and intensity levels to optimize test parameters for the best compromise of speed and thoroughness. All testing levels are user selectable prior to testing. At the time of purchase, the user may specify preset levels that will fulfill his testing requirements. If not specified, the most common preset test parameters will be provided. Mechanical signal switches and calibration pots, which are a major cause for instrument failure and calibration drift, have been eliminated.
