Environmental Classifier

Hearing instruments have complex sound processing that adapts to the listening environment. One way they do this is by recognizing characteristics of incoming sound and categorizing them in a meaningful and accurate way.

Environmental Classifier employs sophisticated speech and noise detection algorithms based on frequency content and spectral balance, as well as the temporal properties of the incoming sound. Furthermore, the classification is calculated on the basis of probabilistic models, resulting in classification of listening environments which has shown a high degree of consistency with listener perception. Automatic control of feature settings based on the acoustic environment is transparent and natural-sounding. The user benefits without noticing changes in the sound processing.
