SOUND PROCESSING APPARATUS, SOUND PROCESSING METHOD AND HEARING AID

WIPO Patent Application WO/2011/048813

A1

Provided are a sound processing apparatus, a sound processing method and a hearing aid whereby the voice of a speaker in the vicinity of the user can be efficiently emphasized independently of the distance between the disposed microphones. The sound processing apparatus uses output signals of the respective ones of a plurality of omnidirectional microphones to output a first directional signal, which forms the main axis of a directivity in a speaker direction, and a second directional signal, which forms the dead angle of the directivity in the speaker direction. The sound processing apparatus calculates individually calculates the level of the first directional signal and the level of the second directional signal and determines, based on the levels of the first and second directional signals, far and near relative to the speaker. The sound processing apparatus derives, in accordance with a result of that determination, a gain to be applied to the first directional signal, and uses the gain to control the level of the first directional signal.
