Filter by:Normal-hearing participants aged 18-25 with and without musical training will listen to a series of short musical samples that have been recorded through hearing aids. The music will be played at a comfortable listening level. Subjects will use the computer to rate the sound quality of the music on a 7-point Likert scale.
The current standard of care approach for programming cochlear implants uses a generalized pitch-map for all patients. This approach fails to account for individualized inner ear anatomy. As a result, many cochlear implant recipients experience place-pitch mismatch. We have recently developed an automated mathematical tool to produce patient-specific, customized cochlear implant pitch-maps (Helpard et al., 2021). In this study, cochlear implant recipients will be randomized to receive either the clinical default pitch-map (the control group) or a place-based pitch-map (the intervention group). Assessments will be conducted at multiple time-intervals to account for patient acclimation and plasticity to both the generalized and individualized pitch-maps. Audiological assessments will be tuned to identify patients' ability to discern pitch scaling and variation in sounds, as well as to understand complexities in speech such as mood and tone. Audiological testing will be conducted in collaboration with the National Centre for Audiology (London, ON) to ensure that the most accurate and relevant metrics are applied.
Older adults who use cochlear implants to address hearing loss show wide variation in benefit. This research investigates the role of normal aging, the health of peripheral and central auditory pathways, and positioning of the cochlear implant electrode array in contributing to this variability. A range of input types from simple auditory signals to spoken sentences is used to examine these questions.
The primary objective of this study is to determine the (long term) effect of intervention with a CI in adult participants with progressive postlingual moderate/severe-to-profound sensorineural hearing loss on societal related outcomes (participation; communication profile; autonomy; cognition; listening effort; work; productivity loss; income; medical consumption; third party quality of life; quality of life, and capability). The secondary objective is to determine the effect of CI waiting time between referral and CI surgery on the same societal related outcomes, in the adults with postlingual moderate/severe-to-profound sensorineural hearing loss.
Internal research on the manufacturer's hearing aid products has idenitfied areas in which the investigators can improve the hearing aid frequency response curve. This study aims to investigate the current freqeuncy response curve in the manufacturer's products to variations of these curves to determine if hearing aid users prefer the variations over the manufacturer's standard curve.
Severe-to-profound hearing loss can have a major impact on patients´ lives leading to social isolation and decreased quality of life. Most commonly the hearing loss is caused by damage to the inner ear or cochlear nerve. Since the vestibular system which is central for our balance is located in the inner ear it can be suspected that patients with severe-to-profound hearing loss also might have an impaired vestibular function. This impairment may lead to a feeling of dizziness or vertigo. This study aims to investigate if patients with severe-to-profound hearing loss also have impaired vestibular function. The vestibular function will be measured with caloric irrigation, video head impulse test and vestibular evoked myogenic potential.
This study aims to evaluate a cochlear implant headpiece.
Patients with hearing loss who use cochlear implants (CIs) show significant deficits and strong unexplained intersubject variability in their perception and production of spoken emotions in speech. This project will investigate the hypothesis that "cue-weighting", or how patients utilize the different acoustic cues to emotion, accounts for significant variance in emotional communication with CIs. The results will focus on children with CIs, but parallel measures in postlingually deaf adults with CIs will be made, ensuring that results of these studies benefit social communication by CI patients across the lifespan by informing the development of technological innovations and improved clinical protocols.
This study is to build a cohort of sudden sensorineural hearing loss (SSNHL) patients. When the patient visited the Department of otolaryngology clinic for hearing loss, we can diagnose the SSNHL following the result of pure tone audiometry and the history of the patient. The cohort is a system that tracks the hearing recovery status, timing, and degree of recovery of patients who received cocktail therapy with or without high-dose steroids, vasodilators, antiviral agents, and intratympanic steroid injections, satellite ganglion block, and hyperbaric oxygen therapy.
Severe to profound hearing loss affects 0,8% of the global population. For these people, a conventional hearing aid often does not provide sufficient benefit. However, these people can benefit from a cochlear implant (CI). A CI needs to be individually programmed (fitted) for each recipient. A fitting "map" is defined as a set of electrical parameters that are individually adapted to a recipient's needs to achieve optimal sound perception. At present, most CI recipients are fitted with a default frequency allocation map that doesn't take individual variability in size and shape of the cochlea into account. In this study, a fitting strategy based on the post-operative CT scan, that will allow the audiologist to set a frequency-band distribution for CI fitting that may be more closely aligned to the natural tonotopic frequency distribution of a normal hearing cochlea, will be evaluated.
