摘要：

We investigated the potential benefits for consonant identification of a form of frequency transposition Intended for people with severe or profound hearing loss at high frequencies, but near-normal heartily at low frequencies Frequency components from a "source band in a high-frequency region were transposed downwards to a 'destination band' All experiments used normal-hearing listeners Experiment I showed that (untransposed) source bands centred near 4 kHz yielded highest identification scores Also, performance was better when the source band was wider Experiment 2 used transposition with the 'best' source bands front experiment I. and showed that superimposing the transposed components on the components in the destination band gave better results than replacing the latter by the former Experiment 3 assessed the effects of focused training. using conditions without and with transposition Significant Improvements occurred with training, but overall performance following training was similar for all conditions However, transposition reduced some frequent errors
