Aural Rehabilitation for Cochlear Implant Users Via Telerehab Technology
Hearing LossDeafnessThis study evaluates the benefits of short-term training via telehealth for post-lingually deafened adult cochlear implant users. Half the participants will receive aural rehabilitation and the other half cognitive training. The hypothesis is that short-term aural rehabilitation via telerehab technology will improve outcomes for post-lingually deafened cochlear implant users
Evaluation of Speech-in-noise Performance in Cochlear Implant Recipients With a CROS Device on the...
Hearing LossSensorineuralSpeech understanding in noise remains the greatest challenge for people using cochlear implants, particularly when the speech of interest comes from the side of the head opposite to the implant. Recent findings in hearing technology allow for people to either use a hearing aid or a Contralateral Routing of Signal (CROS) device on the non-implanted ear. Differences in speech understanding may result depending on the device chosen by a person, and these differences may be measureable through speech discrimination measurement methods. This study intends to determine whether or not a CROS device improves speech perception in noise when the source of the speech of interest originates from the side of the head opposite to the implant.
Hearing Aids and the Brain
Hearing LossHearing aids are being fit on inexperienced hearing aid users and the short-term and long-term effects are measured. This research aims to improve understanding of the individual factors that contribute to receiving benefit from hearing aids and lead to more individualized treatment of hearing loss.
Coupler-Based Hearing-Aid Fitting Approach for Experienced Users
Hearing LossThe overall aim of the study is to compare the verification accuracy and hearing-aid outcomes between the traditional, fitting approach where the patient is present during the visit and a coupler-based fitting approach where the patient is not present and mailed their hearing aids. If the coupler-based fitting protocol tested in this study as effective as the traditional fitting protocol, then patients receiving replacement hearing aids may circumvent a face-to-face visit.
New Algorithms to Signal Processing for Speech Enhancement in Adult Cochlear Implant Recipients....
Hearing LossThe purpose of this clinical investigation is to develop pre-processing strategies to enhance speech and reduce noise for CI listeners. The Master Umbrella Clinical Investigation will be comprised of several sub-investigations, which will aim to optimize speech enhancement algorithms, to improve real-world functionality, and to incorporate them efficiently into CI speech processors.
Electrical Impulse Parameters and Neuronal Population in the Cochlear Implanted Patient-PULSE
Sensorineural Hearing LossThe cochlear implant provides good auditory performance despite high inter-individual variability, but performance in noise remains limited. Modification of the coding strategies could improve these performances. A better characterization of the remaining neuronal population by looking for the charge integration efficiency (which depends on the duration and the amplitude of the electrical pulse) would allow an optimization of the settings by adapting either the duration or the amplitude of the pulse according to the quality of the remaining neuronal population.

Hearing Aid Noise Reduction in Pediatric Users Pilot Study (Oticon Pilot Study)
Hearing ImpairmentSensorineural Hearing Loss1 moreThe purpose of this study is to evaluate the efficacy of OpenSound Navigator (OSN), a hearing aid speech-enhancement algorithm developed by Oticon, as treatment for pediatric hearing aid users. The study used a within-subjects design with pre- and post-comparisons involving fifteen pediatric (ages 6-12) patients with symmetrical sensorineural hearing losses ranging from the mild to moderately-severe degree. All participants were fit with bilateral Oticon OPN™ behind-the-ear hearing aids set with the OSN algorithm enabled. The investigators evaluated hearing aid benefit through word recognition in noise (behavioral testing) and everyday hearing/listening abilities (parental/legal guardian reported) within one week of the hearing aid fitting (pre-intervention) and two months post fitting (post-intervention).
Speech Intelligibility in Quiet and Noise for New vs. Legacy Hearing Aids
Hearing LossSensorineural1 moreThis clinical investigation is designed to compare audiological performance (i.e., measurements of sound quality and speech understanding) between Starkey's new receiver-in-canal device and a commercially available legacy receiver-in-canal device.
