Sonic Touch offers several proprietary directional technologies to improve hearing in noisy situations. Touch has several automatic and adaptive directional options that provide hands-free operation in a wide variety of listening environments.
Fixed Directionality
All Sonic Touch products can be configured to use a fixed, non-adaptive directional response.
Automatic Directionality
Using the signal-to-noise ratio, intensity level of the noise, and amount of wind noise as cues, the Automatic Directionality system continuously engages or disengages, providing the best directional configuration for the environment.
Adaptive Directionality – Focused Null Steering
Sonic Touch features two adaptive directional technologies. The first system, Focused Null Steering, constantly monitors the environment for the location of the loudest sound. Once the sound is located, the directional response is adjusted to minimize sounds coming from that direction. If the location of the loudest sound moves, the directional response dynamically updates to continue to reduce the sound.
Adaptive Directionality – DIRECTIONALfocus™
DIRECTIONALfocus, Sonic Touch’s second adaptive directional system, offers a unique and highly effective approach to managing unwanted noise. As the name implies, DIRECTIONALfocus creates a focus area, or “beam”, in front of the listener and varies how much sounds are reduced as they move out of the beam. Touch 24 also provides an additional variation of the DIRECTIONALfocus system. FLEXIfocus allows the DIRECTIONALfocus functionality to dynamically turn on or off based on the amount of noise in the environment. In quiet, FLEXIfocus disengages. As the level of noise increases, FLEXIfocus engages to reduce the amplification of sounds outside of the beam.
