What is Biometric Calibration?
Beginning with the extraction of 1600 data points from the client’s ear impression, the directional response of the hearing aid is designed to take into account the effect the client’s ear anatomy has on incoming sound waves. The result is a custom calibrated and more precise beamformer, providing up to 2dB better directionality for directional models.
