Abstract: A hearing device adapted to be worn by a user and for picking up sound containing the user's own voice is provided. The hearing device includes an input unit having first and second input transducers for converting sound to first and second electric input signals, respectively, representing the sound. The hearing device is configured to provide that the first and second input transducers are located on the user so that the user experiences first and second, acoustically different, acoustic environments, respectively, when the user wears the hearing device. The first acoustic environment may be defined as an environment where the own voice signal primarily originates from vibrating parts of the bones and skin or tissue. The second acoustic environment may be defined as an environment where the own voice signal primarily originates from the user's mouth or nose and is transmitted through air from said mouth or nose to the second input transducer(s). A method of operating a hearing device is further disclosed.

Abstract: A hearing device adapted to be worn by a user and for picking up sound containing the user's own voice is provided. The hearing device comprises a) an input unit comprising first and second input transducers for converting sound to first and second electric input signals, respectively, representing said sound; b) a processor configured to receive said first and second electric input signals and to provide a combined signal as a linear combination of the first and second electric input signals, wherein the combined signal comprises an estimate of the user's own voice, and c) wherein said hearing device is configured to provide that said first and second input transducers are located on said user at first and second locations, when worn by said user; and d) wherein said first and second locations are selected to provide that said first and second electric signals exhibit substantially different directional responses for sound from the user's mouth as well as from sound from sound sources located in an environment around the user. A method of operating a hearing device is further disclosed. Thereby an improved quality of an own voice estimate may be provided.
