“…Previous studies on speech perception with binaurally combined acoustic and electric hearing revealed mixed results ͑for adults, see Dooley et al, 1993;Armstrong et al, 1997;Tyler et al, 2002;Ching et al, 2004; for children, see Chmiel et al, 1995;Ching et al, 2001͒. Chmiel et al ͑1995͒ reported significantly better speech performance in quiet with a combined use of hearing aids and cochlear implants in three of the six subjects.…”

“…Recent development of short-electrode arrays allows the preservation of low-frequency acoustic hearing in these patients ͑von Ilberg et al, 1999;Gantz and Turner, 2003͒. For those who are implanted with the conventional long-electrode arrays, low-frequency acoustic information is also available by combining electric hearing with acoustic hearing from the nonimplanted ear ͑Dooley et al., 1993;Tyler et al, 2002͒. Availability of these individuals allows a unique opportunity to study the role of fine-structure information at low frequencies in auditory perception, particularly in tasks that depend on pitch perception ͑i.e., music perception and speech recognition in the presence of a competing talker͒.…”

Speech recognition in noise and music perception is especially challenging for current cochlear implant users. 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. The first experiment measured speech recognition in the presence of competing noise. It was found that, although the residual low-frequency ͑Ͻ1000 Hz͒ acoustic hearing produced essentially no recognition for speech recognition in noise, it significantly enhanced performance when combined with the electric hearing. The second experiment measured melody recognition in the same group of subjects and found that, contrary to the speech recognition result, the low-frequency acoustic hearing produced significantly better performance than the electric hearing. It is hypothesized that listeners with combined acoustic and electric hearing might use the correlation between the salient pitch in low-frequency acoustic hearing and the weak pitch in the envelope to enhance segregation between signal and noise. The present study suggests the importance and urgency of accurately encoding the fine-structure cue in cochlear implants.

“…In these contralateral ear studies, the patients were implanted with a standard-length electrode in one ear, and generally used a hearing aid in the contralateral ear. Dooley et al (1993) reported benefits from providing amplified (and signal-processed) speech to the contralateral ear. Mok et al (2006) reported benefits when amplification was provided to the contralateral ear for approximately one-half of their 14 subjects.…”

Combined acoustic and electric hearing: Preserving residual acoustic hearing

The topic of this review is the strategy of preserving residual acoustic hearing in the implanted ear to provide combined electrical stimulation and acoustic hearing as a rehabilitative strategy for sensorineural hearing loss. This chapter will concentrate on research done with the Iowa/Nucleus 10mm Hybrid device, but we will also attempt to summarize strategies and results from other groups around the world who use slightly different approaches. A number of studies have shown that preserving residual acoustic hearing in the implanted ear is a realistic goal for many patients with severe high-frequency hearing loss. The addition of the electric stimulation to their existing acoustic hearing can provide increased speech recognition for these patients. In addition, the preserved acoustic hearing can offer considerable advantages, as compared to a traditional cochlear implant, for tasks such as speech recognition in backgrounds or appreciation of music and other situations where the poor frequency resolution of electric stimulation has been a disadvantage.

“…Several authors have reported on the performance of patients who use a traditional long-electrode cochlear implant in one ear and a hearing aid in the contralateral ear [7][8][9]. In general, the contribution of the contralateral acoustic ear has been shown to be quite helpful, particularly for understanding speech in noise backgrounds.…”

Abstract-For some individuals with severe high-frequency hearing loss, hearing aids cannot provide a satisfactory improvement in speech recognition. However, these same patients often have too much residual hearing to qualify as candidates for a cochlear implant. Here we describe results with the Iowa/ Nucleus Hybrid cochlear implant, which is designed to preserve the patient's residual low-frequency hearing while at the same time supplementing their high-frequency hearing through electrical stimulation. The advantages of this approach are presented, including improved speech recognition in competing backgrounds as compared with traditional cochlear implants. The results with the Iowa/Nucleus Hybrid device demonstrate the ability of the auditory system to integrate acoustic and electrical stimulation, even under conditions of severe distortions to the normal cochlear place-frequency mapping.
