Crosslink Directionality 2: Directionality That Supports Natural Auditory Processing

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...

Role of the lateral line mechanosensory system in directionality of goldfish auditory evoked escape response.

Goldfish (Carassius auratus) escape responses to sudden auditory stimuli are mediated by a pair of reticulospinal neurons, the Mauthner (M-) cells, which integrate mechanosensory inputs from the inner ear and the lateral line (LL) to initiate a fast directional response away from the aversive stimulus. This behavior is context dependent; when near an obstruction the fish may rather turn towards...

Non-directionality and Self-Assessment in an Example-based System Using Genetic Algorithms

We show the application of an optimisation technique to natural language processing: genetic algorithms, thanks to the definition of a data structure called board and a formal distance. The system hms two interesting features: non-directionality, whict~ Ls more than hidirectionality, and self-assessment, independently of the inner knowledge. Results of experiments are presented and discussed. T...

Binaural processing by the gecko auditory periphery.

Lizards have highly directional ears, owing to strong acoustical coupling of the eardrums and almost perfect sound transmission from the contralateral ear. To investigate the neural processing of this remarkable tympanic directionality, we combined biophysical measurements of eardrum motion in the Tokay gecko with neurophysiological recordings from the auditory nerve. Laser vibrometry shows tha...
