Filter by:This study investigates the possible benefits of using binaural spatialization techniques in digital wireless microphone systems for hearing aids. Speech intelligibility tests, speaker localization tests and preference tests are performed. The results of a diotic (current rendering) and a binaural (suggested rendering) rendering are compared.
The purpose of this study is to evaluate the long-term safety and efficacy of the Esteem® Hearing Implant in subjects suffering from moderate to severe hearing loss.
The aim of this study is to validate uHear™, an iOS-based tool, as a screening tool to detect significant hearing impairment as part of a comprehensive geriatric assessment in patients aged 70 years and older. The pass or fail screening cut-off is defined as having two or more consecutive hearing grades starting from the moderate-severe threshold zone ranging from 0.5 - 2.0 kHz.
This study examines the effect of an exercise and health education/auditory rehabilitation and socialization intervention on functional fitness, hearing handicap and psychosocial distress measures in older adults with hearing loss.
The aim of this study is to evaluate cerebral asymmetry for face processing in a group of profoundly deaf participants and a group of hearing controls by the mean of fMRI measure. To this end, we present chimeric faces (faces split into different halves), entire faces, or faces presented in divided visual field, and subjects perform a gender categorization task while lying in a fMRI scanner. It is expected to find a reduced cerebral asymmetry in the Fusiform Face Area in deaf in comparison with hearing participants.
Currently, the fitting of hearing aids is using a computer interface that allows to adjust the gain and compression of acoustic amplification. This adjustment is made face to face, patient and audiologist being located in a soundproof space to test the effectiveness of the hearing aid. However, advances in telemedicine in this context, let consider the possibility of addressing these hearing aids fitting via the same computer interface, but remotely controlled by the hearing care professional. The purpose of this study is to assess the ability to perform these tests no longer in front of the patient settings, but away from it, and without visual and sound contact other than through a computer interface. At the end, this project wants to show that a remote fitting is an acceptable procedure that provides comparable results to-face fitting in terms of speech perception, speech in noise audiometry, hearing loss related quality of life in order to be able to offer this type of strategy.
The ability to encode the speech signal is determined by ascending and descending auditory processing. Difficulties in processing these speech signals are well described at the behavioral level in a specific language disorder. However, little is known about the underlying pathophysiological mechanisms. The assumption is that we should observe a degradation of the signal provided by the ear in the deaf subject while in case of specific language impairment it would be a phonemic disorder (possibly linked to a processing disorder auditory). The two population groups should therefore have different abnormalities of their central auditory process - which could be modified by the target remediation for each group.
The purpose of this research study is to test the effectiveness and safety of the study drug, AM-111. AM-111 is tested for the treatment of sudden sensorineural hearing loss where the cause is unknown.
Cochlear implantation enables profoundly deaf children to acquire speech and develop their understanding of spoken language. However, there are significant interindividual differences in the results obtained with the implant. Given the lack of theoretical knowledge on acoustic predictors, cognitive and language to obtain optimum speech recognition with cochlear implants associated with a good communicative and language development of deaf children, the investigators intend to achieve a preliminary longitudinal study aimed to describe the cognitive, communicative and perceptive implanted deaf children. The main objective of our study is to describe the cognitive and communicative development of deaf children implanted from the pre-implant assessment to 18 months post-implantation, by addressing the following aspects: - The psychomotor and cognitive development assessed using the Brunet-Lézine test; - The development of preverbal communication, evaluated using the Early Social Communication Scale.
The objective is to study the relation between the reorganization of the central auditory system, and the psychophysical deficits in binaural hearing in subjects with single sided deafness.
