Simplified cochlear frequency selectivity assessment in normal-hearing and hearing-impaired listeners
ObjectiveThe ear's spectral resolution or frequency selectivity (FS) is a fundamental aspect of hearing but is not routinely measured in clinical practice. This study evaluated a simplified FS testing procedure for clinical use by replacing the time-consuming two-interval forced choice (2IFC) m...
