TL;DR: Through the multi-channel spectral display of the Tactaid 7 device, subjects were able to identify roughly 2 bits of information in each of four 10-item sets of sounds representative of different environmental settings.

TL;DR: Consonant discriminability by normal-hearing listeners was studied for monosyllables processed using frequency lowering with either uniform (linear) or nonuniform (warped) compression of the frequency axis, finding that lowering was superior to filtering for contrasts of fricative sounds but inferior for contrasted of nasals and semivowels.

TL;DR: A modality-independent upper limit to language processing is suggested as evidenced by a substantial drop in intelligibility in this region and by a shift in error patterns away from semantic and toward formational.

TL;DR: The results indicate that the matched intensity of the 200-Hz auditory tone is less when the A+T and A+A stimuli are close together in frequency than when they are separated by an octave or more, further supporting a strong frequency relationship between the auditory and somatosensory systems.

TL;DR: The results on psychoacoustic and phoneme identification measures illustrate the effects of broader filtering in CI hearing contributing to reduced pitch perception and increased spectral masking and provide further evidence that CI listeners obtain little to no release of masking in temporally gated noise compared to stationary noise.
