In addition to being a fully functional Bluetooth headset, Acapella incorporates an advanced state of the art hearing solution. Acapella's new programming in environmental sound detection, its unrivaled 128-bands of Noise Reduction, superior feedback cancellation, built-in feedback path measurement capabilities, sets a new standard of performance and features in digital hearing aid solutions. Acapella incorporates a new programming strategy to a single program setting which can be employed by the user in all environments instead of manually changing to a different memory with a change in the acoustic environment. The brand-new algorithm automatically senses wearer's environment and dynamically adjusts hearing enhancement algorithms (such as Feedback cancellation, Noise Reduction, Compression etc.) without any user involvement. Acapella’s programming accurately predicts speech in quiet, speech in noise, wind, music, quiet and noise environments and make the necessary adjustments to the parameters in the audio path in a gradual smooth and virtually unnoticeable manner. This feature will enable the hearing aid wearer to have an instrument which will work in any environment with a single memory.
