Abstract
A wearable electronic device includes a neck-wearable housing, generally U-shaped, with an electrical connector; two in-ear earphones; two cords, with one end connected to one of the earphones and the other end connected to the connector. The two cords are mechanically connected to the housing. Points of connection of the cords to the housing are close to each other and form a dorsal node, and the two cords are mechanically connected to each other in their portions between the in-ear earphones and the dorsal node to form a suboccipital node. A microphone is placed in the housing on a front (chest) side of the user. A microphone is placed in the dorsal and/or in the suboccipital node. The microphones are used for determination of correlated and non-correlated components of audio signals. The correlated components are treated as a noise signal and the non-correlated components are a target signal.
