Abstract: The present disclosure relates to an audio device and method for controlling ambient sound through a unified system. The device integrates passive isolation, active noise cancellation (ANC), and passthrough functionality to provide a seamless and customizable auditory experience. By employing a combination schema, users can adjust noise attenuation and amplify specific frequency ranges, such as human voices, to achieve a flat or tailored audio response. The system incorporates intuitive controls, such as dials or sliders, to modify settings in real time, and visual indicators to display adjustments.
