CrossLink Directionality: Facilitating true binaural auditory processing

Effect of Directional Strategy on Audibility of Sounds in the Environment

Directional microphones in hearing aids have been well-documented to improve speech recognition in noise in laboratory conditions. The real-world perceived benefits of directionality have been less dramatic. The development of directional technology during the past decade has focused on improving laboratory benefit by means of adaptive behavior, and more recently, binaural beamforming made poss...

Crosslink Directionality 2: Directionality That Supports Natural Auditory Processing

Improved Cocktail - Party Processing

The human auditory system is able to focus on one speech signal and ignore other speech signals in an auditory scene where several conversations are taking place. This ability of the human auditory system is referred to as the “cocktail-party effect”. This property of human hearing is partly made possible by binaural listening. Interaural time differences (ITDs) and interaural level differences...

Sensory Behavior of Naval Personnel: M on Aural/binaural Minimum Audible Angle of Auditory Response

This paper considers what one ear contributes to man's perception of his auditory world and evaluates the monaural/binaural role in spatial orientation. Minimum audible angles were determined for monaural listening to moving sounds, and results were compared to similarly obtained binaural data. Much usable directionality existed for the monaural mode even at poor azimuths, and for both modes of...

Binaural fusion and the representation of virtual pitch in the human auditory cortex.

The auditory system derives the pitch of complex tones from the tone's harmonics. Research in psychoacoustics predicted that binaural fusion was an important feature of pitch processing. Based on neuromagnetic human data, the first neurophysiological confirmation of binaural fusion in hearing is presented. The centre of activation within the cortical tonotopic map corresponds to the location of...
