Filter by:The current study is a dubble-blinde placebo-controlled cross-over study verifying the preventive effect of antioxidants on noise-induced hearing loss (NIHL) and noise-induced tinnitus (NIT). The antioxidants comprise of a mixture of magnesium and n-acetylcystein which should be taken 1h before leisure noise above 100dB for at least 30 minutes.
People with single-sided deafness (SSD) have significant hearing loss in one ear and normal or near normal hearing in the other ear. Those living with SSD experience several communication difficulties, particularly when listening to speech in the presence of background noise. This problem is worse in situations where the noise is on the side of the good ear and the speech is on the side of the poor ear. The Bone-Anchored Hearing Aid (BAHA) and the Contralateral Routing of Signals (CROS) hearing aid are two devices designed to improve hearing in people who have significant hearing loss in one ear only. The BAHA is a surgically implanted device which also includes an external processor; sounds from the poor ear are transmitted to the good ear through skull vibrations. The CROS does not involve surgery; instead a hearing aid is fitted behind each ear, and the sounds on the side of the poor ear are wirelessly transmitted to the good ear. The majority of previous studies comparing the BAHA to the CROS have used older CROS models with basic technology and a wire along the neck to send sounds from the poor ear to the good ear. There is a lack of studies comparing newer digital wireless CROS hearing aids to the BAHA. The current research will compare the effect of the BAHA and CROS hearing aid on speech perception scores when listening to speech in quiet and in noise. The research will also investigate patients' reported benefits with each device during everyday situations. In order to compare the BAHA and CROS, individuals who already have been implanted with a BAHA will be given a trial period with a new wireless digital CROS hearing aid. The research hypothesis states that the CROS hearing aid will be as equally beneficial or greater than the BAHA in improving hearing and patient benefit. If the findings support the hypothesis that the CROS offers just as much benefits as the BAHA, or is an even better alternative, more patients may choose to avoid surgery and decide to receive a CROS hearing aid instead.
The goal of this study is to determine whether daily assessment and feedback of workers' noise exposures leads to more effective use of hearing protection and prevention of noise-induced hearing loss.
To assess implant stability, implant loss, adverse skin reactions, and Quality of Life Benefit following implantation of the Ponto 4.5mm Wide Diameter implant. Secondary: to determine the feasibility of fitting the sound processor 3 weeks after surgical implantation, and to investigate if the type of skin reactions following implantation could be related to the demographic data of subjects and the type of surgical technique used
The objective of this feasibility study is to obtain preliminary safety and efficacy data associated with cochlear implantation in individuals with severe to profound sensorineural hearing loss contralateral to an ear with normal, or near-normal, hearing. The hypothesis is that restoration of hearing in the deafened ear will result in improved speech perception in the treated ear and advantages related to restoration of hearing to both ears.
The objective of the trial is to investigate whether early treatment with oral valganciclovir of infants with both congenital cytomegalovirus infection and sensorineural hearing loss can prevent progression of hearing loss.
This is an international, multi-center, double-blind, placebo-controlled evaluation valganciclovir treatment for up to 54 children (up to 4 years of age) with virologically-confirmed congenital CMV infection and hearing loss. Subject participation will be over a six-month period and study subjects will be stratified according to age. The primary objective is to assess whether a six-week course of oral valganciclovir can stabilize the hearing of children with congenital CMV infection who present with hearing loss.
The purpose of this study is to determine whether ancrod is effective and safe in the treatment of sudden sensorineural hearing loss (SSHL).
The primary purpose of the research is to study how individuals who wear cochlear implants process sounds in noisy environments and also whether newly designed programs can help improve the communicative ability of cochlear implant patients in noisy situations.
The purpose of this study is to determine whether the use of 'patient journey' model in internet-based counseling of a person with hearing impairment is a feasible approach in management of emotional and social consequences, anxiety and depression, readiness to change and acceptance of hearing loss.
