Environmental Optimizer

Provide automatic adjustment of hearing instrument settings.

End user benefit
Users enjoy optimal audibility and listening comfort even when moving through rapidly changing sound environments, and without needing to make frequent manual adjustments.

It is well-known that hearing aid users often have varying preferences for hearing aid volume depending on the listening environment. Therefore, when the Environmental Classifier identifies an environment, the Environmental Optimizer automatically adjusts the volume, which saves the user the trouble of frequent manual adjustments of volume control or program change.

Environmental Optimizer II

In addition to volume per environment, Environmental Optimizer II has individually tailored adaptive noise reduction (NoiseTrackerâ„¢ II) assigned to each environment. It is an extraordinary solution for hearing aid users because both the need to adapt to multiple listening environments and comfort in noise are balanced.
