2cc: Curve display option that shows the gain or output of the hearing instrument as measured in a 2cc coupler. Unitron TrueFit™ automatically displays values in the appropriate coupler for the selected hearing instrument: an HA-1 for custom products and an HA-2 for BTE products. The graph options are accessed from the graph icon at the top right of the graphs.

A

Adaptation Manager: Control which adjusts the overall gain in the hearing instrument to provide a percentage of the prescribed target for the current fitting formula. An automatic component can be activated to gradually transition from a current setting that is focused on providing acceptable initial loudness (current setting) to a setting designed to optimize speech understanding (end value). Both the current and end value settings are adjusted by moving the position of the slider controls. The adaptation manager is a global parameter and therefore affects all programs.

 

Adaptive Directional: This input option uses an adaptive directional polar pattern strategy to improve speech understanding in noise. 

 

AntiShock™: A feature which is able to instantly identify and minimize impulse sounds without eliminating or making the sounds unrecognizable and without affecting speech sounds. This adjustable feature works independently from the gain, MPO and the compression system.

 

AntiShock™ 2: Instantly suppresses sudden loud, irritating sounds without affecting speech and sounds your patients want to hear.

 

Audio Streaming: Input that is provided by wireless transmission of signals (e.g., via uDirect™ inputs or Binaural Phone).
