Among risk factors of neurodevelopmental disorder is congenital hearing loss. However, congenital deafness is neither necessary nor sufficient for the occurrence of warning signs of neurodevelopmental disorder. The investigative team hypothesizes that the co-occurrence of these two clinical entities results from a common origin, within a syndromic diagnosis including other medical issues. These situations would therefore be very different from those of babies suffering from isolated sensorineural deafness. This study aims to identify which factors are statistically correlated with the association of congenital deafness and early symptoms of neurodevelopmental disorder, thanks to a partnership between a regional center for psychiatry of deaf children (Therapeutic Childhood and Deafness Unit of St Maurice Hospitals, UTES) and a pediatric audiophonology department (ENT department of the Necker-Enfants Malades hospital). This work is based on a cohort of 26 children under ten months of age diagnosed with severe to profound congenital sensorineural hearing loss. As part of their pre-implantation cochlear assessment, a consultation was filmed to precisely analyze the interactional and sensorimotor skills of these children (clinical observations, administration of a specific evaluation grid called Olliac Grid), after reviewing the films. The investigative team will then be able to grade the neurodevelopmental risk. In order to clarify what factors are linked with a neurodevelopmental risk, medical data concerning the child's family context, birth, and audiological profile will also be collected, and put in perspective with the assessed neurodevelopmental risk gradation.
Overhearing is important for vocabulary learning and speech and language development in young children. However, contemporary hearing aids are generally unable to provide adequate access to low-level auditory inputs from multiple talkers at a distance to capitalize on overhearing. A recent investigation by Jace Wolfe and colleagues showed that, even when aided, children with hearing loss had significantly poorer speech recognition at 40, 50 and 60 dBA compared to children with normal hearing. Furthermore, they showed that increasing hearing aid gain for very low-level inputs produced a statistically significant improvement in syllable-final plural recognition and a non-significant trend toward better monosyllabic word recognition at very low presentation levels. Additional research is needed to document low-level speech recognition ability of children with hearing loss as well as the potential benefit or detriment of increasing hearing aid gain for low-level inputs. A novel hearing aid technology known as Soft Speech Enhancer has been shown improve low-level speech perception in adults with hearing loss; however, the effect of Speech Enhancer on speech recognition in children is not yet known and will be evaluated.
Participants with hearing loss and Tinnitus will wear hearing aids with amplification-only or with an added sound, and have their tinnitus level evaluated before and after intervention.
This clinical study aims to investigate speech performance in quiet with an OTE Sound Processor with modified firmware compared with the commercially available CP1150. The study also investigates CP1110 and CP1150 with Forward Focus.
The aim of this study is to understand how audiometric, cognitive and electrophysiological results relate to sentence recognition score in adults using currently a Nucleus cochlear implant.
Dysarthria and hearing loss are communication disorders that can substantially reduce intelligibility of speech and the addition of background noise adds a further challenge. This proposal utilizes an established signal processing technique, currently exploited for improved understanding of speech in noise for listeners with hearing loss, to investigate its potential application to overcome speech-in-noise difficulties for listeners understanding dysarthric speech. Successful completion of this project will demonstrate proof-of-concept for the application of this signal processing technique to dysarthric speech in noise, and inform the development of an R01 proposal to perform a large-scale evaluation of the technology, and clinically meaningful implications, in a broad range of disordered speech types and severities.
Hearing comprehension under complex listening conditions is considered to be the central complaint of everyday life for patients with cochlear implants. Localization is one of the cues for listening comprehension. However, only few studies have investigated the effect of spatial localization training on listening comprehension performance in noise. None of these studies correspond to the desire to purpose training by speech therapists while using affordable equipment. The main objective of this study is to evaluate the effect of a spatial localization training protocol in cochlear bi-implanted subjects with post-lingual deafness on their ability to understand in noise. 2 groups of 10 subjects each will be recruited: a patient group and a control group. The patient group will undergo 8 sessions of spatial localization rehabilitation lasting an average of 45 minutes each. After this programme, the pre-test and post- test results obtained will be compared.
The present study will investigate the benefit of hearing aids for speech intelligibility (in both quiet and noisy environments) compared to the unaided condition. Participants will include adults with moderate to moderately severe hearing impairment. The participants will complete laboratory-based speech intelligibility assessments with binaural hearing aids and without hearing aids.
Participants will be comparing the sound quality of their own voice and the sound quality of streamed music using universal couplings and a custom earmold with a dynamic vent.
