Assessment of Novel Sound Changing Principles in Hearing Instruments to Determine Their Application...
Hearing LossParticipants will take part in both a passive and active emotion recognition task: (1) passively listening to semantically-neutral sentences with emotional prosody, and (2) actively listening and subsequently categorizing emotional sentences and sounds. Participants are seated and instructed to stare at a fixation cross while the stimulus is played. During this study, non-invasive physiological measurements of pupil dilation will be recorded from the participants. Using this paradigm we will be assessing the effect of frequency lowering on emotion recognition. The study takes the form of a partly three factorial design (passive task x frequency lowering x acclimatization). Participants also perform a two factor design (active task x frequency lowering). Each participant performs two passive tests (20 minutes long each) with frequency lowering on and off, and a four week acclimatization period in-between. Participants perform one active listening task after the acclimatization period with frequency lowering on and off.
Speech Recognition Training in Children With Hearing Loss
Hearing LossclEAR's auditory brain training has been shown to be effective in improving childrens' abilities to recognize the speech of generic talkers in a laboratory setting. In the proposed research, the researchers will build upon these results and assess the extent to which auditory brain training delivered via the web enhances children's abilities to recognize the speech of a potential classroom teacher and diminishes their communication challenges that are associated with significant hearing loss. First, investigators will conduct focus groups with children who have undergone training with the research version of clEAR's pediatric games, then they will recode the games from LabView to Java Script, making changes in the games in response to the focus group comments, and finally, they will collect data from 20 children to assess whether web-based auditory brain training improves their abilities to recognize the speech of their (hypothetical) upcoming school year's classroom teacher.
Physiological, Behavioural and Subjective Measures of Listening Effort
Hearing LossParticipants will perform two different listening tasks: (1) listening to, and repeating back, sentence lists presented in noise, and (2) listening to short radio excerpts and answering subsequent comprehension questions. At the same time participants are required to perform a manual target-tracking task on a touch screen. During this study, continuous, non-invasive physiological measurements (heart rate, skin conductance and hemoencephalography) will be made from participants. Using this paradigm we will be assessing the effect of different hearing aid processing algorithms on listening effort. The study takes the form of a three factor (listening task x algorithm x signal-to-noise ratio), within-subjects design. Each participant performs each listening task (about 4min long each) with each algorithm (reference, noise reduction I, noise reduction II), at two signal-to-noise ratios (+4 decibel and 0 decibel) twice (test-retest).
Hearing Aid Noise Reduction in Pediatric Users (Oticon Study)
Hearing ImpairmentHearing 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. Using a double-blind experimental design, the investigators aim to compare two treatment groups of pediatric (ages 6-12) patients with symmetrical sensorineural hearing losses ranging from the mild to moderately-severe degree. One group will be fit with bilateral Oticon OPN™ behind-the-ear hearing aids set with an omni-directional microphone setting. The other group will be fit with the same hearing aid model with the OSN algorithm enabled. Participants from the groups will be age and audiogram-matched. The investigators will evaluate hearing aid benefit through word recognition in noise (behavioral testing) and everyday hearing/listening abilities (parental/legal guardian reported) at hearing aid fitting and 6-8 months post fitting.
Remote Microphone Candidacy Study
Hearing LossSensorineuralDespite improvements in digital hearing aid technology, many hearing aid users continue to report difficulty understanding speech in challenging listening environments. Remote microphones have been shown to provide benefit in the most common of these challenging listening environments: distant speakers, background noise, and reverberation. Despite demonstrated benefit, there is a low rate of remote microphone use among adult hearing aid users. One reason for low uptake may be an uncertainty among hearing healthcare providers and potential users regarding expected clinically relevant benefit. This clinical trial will attempt the following: To describe the range of remote microphone benefit among adults with mild-to-moderate sensorineural hearing loss To determine specific individual factors beyond the audiogram that are associated with greater benefit from remote microphones
Clinical Performance, Safety and Patient Reported Outcomes of an Active Osseointegrated Steady-State...
Hearing LossThe aim of this clinical investigation is to collect data on objective and subjective hearing performance, quality of life and safety in adult subjects with conductive hearing loss, mixed hearing loss or single-sided sensorineural deafness.
Bimodal, CROS and Severe Profound Hearing Loss Study
Cochlear ImplantSevere-Profound Hearing Loss4 moreThe study will involve the comparison of three groups with severe-profound hearing loss. Patients with a Cochlear Implant only, patients with a cochlear implant and Hearing Aid, and finally patients with two hearing aids. This will enable a comparison of standard fitting protocols against the new rationale using the same devices. Devices used for patients in all 3 groups are now available in standard of care, and can be kept afterwards should the patients wish.
