From acoustics to cognition: Some suprising results

Bruce A. Schneider


The relationship between acoustics and cognitive functioning which enhances the ability of humans to encode and recall information is discussed. The study reveal the evidence that the acoustical environment determines not only the hearing power but also the thinking power. There is emerging evidence that auditory system is under top-down control, and that both the flow of processing and the emphasis given to certain kinds of processing may change according to context and task demands. The study shows that within an integrated model of sensory and cognitive processing, the quality of the auditory system greatly effect the cognitive performance.
