    Abstract: A system and method of reproducing an audio signal produced by an audio system which includes an earphone is described. The method including the steps of: receiving an audio signal; estimating short-term characteristics of the acoustic exposure of a listener; recording the short-term characteristics; controlling the audio signal and; outputting the controlled audio signal for reproduction. The system or method of the invention may be applied to any sound reproduction system that reproduces sounds by way of an earphone such as telephone headsets or handsets, personal music players, mobile telephones, and two way radios.

    Abstract: A system and method that reduces the perceptual effect resulting from ear occlusion is disclosed. It comprises of an electro-acoustic feedback network that produces phase cancelling sounds in the ear, where a receiver and a microphone are located. A novel control mechanism is disclosed that controls the response of the feedback network to minimise distortion in the ear while maintaining a desired frequency response for external signals. Devices producing the external signal include hearing aids, personal sound devices, in ear monitors, communications headsets and hearing protectors. The integration of the present invention with these devices improves the user's perception of their own voice.
