Assessment of Novel Sound Changing Principles in Hearing Instruments to Determine Their Application...
Hearing LossNormal HearingAn EEG study using continuous speech stimuli to assess neural language processing in a hearing impaired population. Participants listen to short radio excerpts in different Signal to Noise Ratios (SNR) and answer comprehension questions as well as listening effort questions. We assess the effect of different algorithms on neural language processing as well as subjective listening effort. Each participant hears 12 randomized segments of speech (about 4min long each) with different settings on their hearing aid (reference condition, noise reduction algorithm, beam forming algorithm). This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.
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.
HEARS-SLP: Providing SLP-Delivered Hearing Health Care to Individuals With Cognitive Impairment...
Hearing LossDementia1 moreBuilding upon the HEARS audiologist-community health worker (CHW) model, this study intervention will be delivered by a speech-language pathologist (SLP). The primary objective of the study is to develop and test an affordable and accessible hearing rehabilitative intervention that will be delivered by a SLP to individuals with cognitive impairment.
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).
