We have investigated the psychophysical properties of low-frequency hearing, both before and after implantation, to see if we can account for the benefit to speech understanding and melody recognition of adding acoustic stimulation to electric stimulation. In this paper, we review our work and the work of others and describe preliminary results not previously published. We show (a) that it is possible to preserve normal or near-normal nonlinear cochlear processing in the implanted ear following…

THE PSYCHOPHYSICS OF LOW-FREQUENCY ACOUSTIC HEARING IN ELECTRIC AND ACOUSTIC STIMULATION (EAS) AND BIMODAL PATIENTS.
TLDR
It is demonstrated that a small masking release is possible with acoustic hearing in just one ear, with the degree ofmasking release being correlated with the low-frequency pure tone average in the non-implanted ear.
HEARING, PSYCHOPHYSICS, AND COCHLEAR IMPLANTATION: EXPERIENCES OF OLDER INDIVIDUALS WITH MILD SLOPING TO PROFOUND SENSORY HEARING LOSS.
TLDR
It can be concluded that older individuals with mild sloping to profound sensory hearing loss have very little to no residual nonlinear cochlear function, resulting in impaired frequency selectivity as well as poor speech recognition in modulated noise.
Combined Electric and Acoustic Stimulation With Hearing Preservation: Effect of Cochlear Implant Low-Frequency Cutoff on Speech Understanding and Perceived Listening Difficulty
TLDR
For standard-electrode CI recipients with preserved hearing, spectral overlap of acoustic and electric stimuli yielded significantly better speech understanding and less listening effort in a laboratory-based, restaurant-noise simulation.
Speech masking release in Hybrid cochlear implant users: Roles of spectral and temporal cues in electric-acoustic hearing.
TLDR
Performance in all three measures was poorest when EAS CI users were tested using the E-Only listening mode, with significant improvements in A-Only and EAS listening modes, which likely indicates that TFS cues provided by residual hearing were used to obtain speech masking release, which aided sentence recognition in noise.
Combined Electric and Acoustic Stimulation (EAS) in Children: Investigating Benefit Afforded by Bilateral Versus Unilateral Acoustic Hearing
TLDR
It is suggested that children with acoustic hearing preservation may not exhibit initial EAS benefit for speech recognition in semi-diffuse noise; however, because none exhibited a decrement in performance with bilateral acoustic stimulation, EAS fittings are recommended to provide bINAural acoustic access allowing for EAS adaptation to binaural cues over time.
Treatments for partial deafness using combined electric and acoustic stimulation of the auditory system
TLDR
The new results demonstrate that patients with high levels of residual hearing (PDCI levels) receive benefits from cochlear implantation that are at least as great as the benefits received by patients with lower levelsof residual hearing.
Cochlear Implantation With Hearing Preservation Yields Significant Benefit for Speech Recognition in Complex Listening Environments
TLDR
It is suggested that preserved low-frequency hearing improves speech understanding for CI recipients, and testing in complex listening environments, in which binaural timing cues differ for signal and noise, may best demonstrate the value of having two ears with low- frequencies.
Fundamental Frequency Information for Speech Recognition via Bimodal Stimulation: Cochlear Implant in One Ear and Hearing Aid in the Other
TLDR
The higher scores obtained in the CI/HA condition than with CI alone in both of the task-specific tests suggested that the use of a contralateral HA provides improved low-frequency information, resulting in better performance by theCI/HA users.
Electro-Tactile Stimulation Enhances Cochlear Implant Speech Recognition in Noise
TLDR
The positive results suggest that the complementary auditory and tactile modes also be used to enhance performance for normal hearing listeners and automatic speech recognition for machines.
Interaural time processing when stimulus bandwidth differs at the two ears.
TLDR
The data suggest that listeners have difficulty attending to ITD differences in one spectral region when there are other spectral regions that contain conflicting or inconsistent spatial information, which is likely to be the case for many CI patients who possess bilateral residual hearing.

Speech and melody recognition in binaurally combined acoustic and electric hearing.
TLDR
The present study utilizes the residual acoustic hearing in the nonimplanted ear in five cochlear implant users to elucidate the role of temporal fine structure at low frequencies in auditory perception and to test the hypothesis that combined acoustic and electric hearing produces better performance than either mode alone.
Combined Electric and Acoustic Stimulation of the Auditory System: Results of a Clinical Study
TLDR
Synergistic effects of EAS were most prominent for hearing in noise with increases of up to 72% as compared to cochlear implant alone.
Combining acoustic and electrical speech processing: Iowa/Nucleus hybrid implant
TLDR
The human ear has the capability to integrate both acoustic and high-frequency electrically processed speech information and such a device can provide a substantial benefit in terms of speech understanding to those with severe high- frequencies hearing loss, while still maintaining the benefits of the residual lower-frequency acoustic hearing.
Noise Susceptibility of Cochlear Implant Users: The Role of Spectral Resolution and Smearing

TLDR
Findings suggest that implant users’ susceptibility to noise may be caused by the reduced spectral resolution and the high degree of spectral smearing associated with channel interaction, which may improve implant performance in noise, especially for temporally modulated noise.
Effects of noise and spectral resolution on vowel and consonant recognition: acoustic and electric hearing.
TLDR
The best cochlear implant user showed similar performance with the CIS strategy in quiet and in noise to that of normal-hearing listeners when listening to correspondingly spectrally degraded speech, suggesting that the noise susceptibility of co chlear implant users is at least partly due to the loss of spectral resolution.
Combining acoustic and electrical hearing.
TLDR
The human ear has the capability to integrate both acoustic and high- frequencies electrically processed speech information and such a device can provide a substantial benefit in speech understanding to individuals with severe high-frequency hearing loss, while still maintaining the benefits of the residual lower-frequency acoustic hearing.
Masker phase effects in normal-hearing and hearing-impaired listeners: evidence for peripheral compression at low signal frequencies.
TLDR
The presence of cochlear-based compression at low frequencies was investigated by measuring phase effects in harmonic maskers, suggesting that normal peripheral compression remains strong even at 250 Hz and maximum differences in masked threshold were correlated with auditory filter bandwidths at the respective frequencies.
Combined electric and contralateral acoustic hearing: word and sentence recognition with bimodal hearing.
TLDR
The data suggest that a full-insertion cochlear implant is a viable treatment option for patients with low-frequency residual hearing and the combination of an implant and contralateral acoustic hearing yields comparable performance to that of patients with a partially inserted implant and bilateral, low- frequencies acoustic hearing.
Cochlear implants: some likely next steps.
TLDR
Some likely possibilities for further improvement are described, including combined electric and acoustic stimulation of the auditory system for patients with significant residual hearing, use of bilateral implants, and applications of knowledge about factors that are correlated with outcomes to help patients presently at the low end of the performance scale.
Accuracy of Cochlear Implant Recipients on Pitch Perception, Melody Recognition, and Speech Reception in Noise
TLDR
Low-frequency acoustic hearing improves pitch discrimination as compared with traditional, electric-only cochlear implants, and these findings have implications for musical tasks such as familiar melody recognition.
