Description

This project of is a part of the project "Determination of the critical band/auditory filters at low frequencies". The objective is to characterize frequency selectivity for a group of normal hearing subjects in a frequency range that includes both low and mid-frequencies, thus allowing comparison with earlier work. A listening experiment was carried out for this purpose in 2009. The notched-noise method was used, and a total of 12 subjects participated. The range of centre frequencies where characteristics of the auditory filter were estimated was from 50 Hz up to 1000 Hz. Results therefore included new estimates in the frequency range below 100 Hz, where no results had previously been reported. Factors affecting frequency selectivity could therefore be compared across frequency. Modifications to the method, for its proper application in the low frequency range, were as well examined and applied. A manuscript reporting these results was started in 2009 and published in 2010.
