Project Details


The purpose of this project is to characterize human frequency selectivity in the low-frequency range. The project involves investigation of human sound perception of sonic and infrasonic sounds (frequencies above and below approx. 20 Hz). Experimental data is required, which involves the design and completion of psychoacoustic listening experiments, carried out on normal hearing human subjects. Experimental conditions require controlled low-frequency sound reproduction by means of dedicated laboratory facilities. Analysis of data involves the study and application of auditory models, aiming to describe the relevant physiological mechanisms that influence frequency selectivity in the low-frequency range. New findings are expected to contribute to auditory perceptual models, and in turn, provide a tool for prediction and assessment of problems produced by low-frequency noise.
