Abstract (en)
[origin: WO0001196A1] The invention relates to an open-canal communication device (330) and method for processing sound that is delivered directly in a user's open ear canal (350), so that the user will perceive the sound to have a high quality and a flat frequency response. This is accomplished by enhancing sound intensities (320) at frequencies below the ear canal resonance frequencies, reproducing sound in the canal resonance frequency bands with a flat response, and enhancing sound intensities at higher frequencies.
