Filter by:The focus of this project is on a physiologic auditory response called the Medial Olivocochlear Reflex (MOCR) that assesses peripheral neural function. While neural hearing loss is a significant auditory disorder in patients of all ages, more than 50% of newborn infants are screened with a technology that is not sensitive to abnormalities in neural function. The development of a time-efficient and sensitive test system to assess the MOCR will provide significant benefit to infants and patients of all ages with neural deficits who would otherwise go undetected.
Phonak Hearing Systems pass through different development and study stages. At an early stage, feasibility studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interdependency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, as a result, they get optimized. Afterwards, and prior to product launch, the Phonak Hearing Systems undergo a final quality control in terms of clinical trials. This is a pre-validation study, investigating optimized algorithms, features, functions and wearing comfort. This will be a clinical investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).
Prosody is the melody and rhythm of speech, it is used to refer to the supra segmental aspects of speech including pitch, loudness and duration. Variations in these features achieve different prosodic functions and are perceived by the listener as meaningful changes. The role of prosody in language acquisition and effective communication is documented in research. Nevertheless, prosodic intervention in children with hearing impairment received less attention compared to other speech and language areas. The aim of this study is to adapt the "prosody treatment program", an evidence based rehabilitation program, and to detect the efficacy of its activities in improving the prosodic skills of Egyptian hearing impaired children. The "prosody treatment program" is an evidence-based practice targeting receptive and expressive prosodic skills in addition to speech production, intelligibility, pragmatics and phonology. The program is applied using a systematic approach of providing cues following the principles adapted from dynamic temporal and tactile cueing (DTTC) for speech motor learning to help accelerate the child's learning of the prosodic skills targeted in this program. The program was translated to Arabic and adapted to be suitable for the Egyptian children.
Background: Reminding people they are moral adaptable human beings ("self-affirming") reduces the perceived stigma associated with wearing hearing aids and increases actual hearing aid use. The proposed study aims to reduce stigma in a representative sample of people aged over 60 from the general population who may or may not already be wearing hearing aids and improve multiple hearing health outcomes (e.g., attending screening, device use). Methods/Design: Double-blinded randomized controlled trial in which a representative sample of people aged over 60 from the general population will be asked to complete surveys about hearing stigma, hearing loss and multiple hearing health outcomes. Participants randomized to the control group will only complete the survey; participants in the intervention group will be asked to affirm their values. Six months later, all participants will complete the same survey to assess outcomes. Discussion: The proposed research will lead to a brief psychological intervention to reduce stigma in relation to hearing loss/aids.
This is a Phase 1b, prospective, randomized, double-blind, placebo-controlled, single-dose, multicenter, safety study of FX-322, administered by intratympanic injection, in adults with severe sensorineural hearing loss.
The purpose of this study is to investigate the functional benefits of frequency compression vs no frequency compression or fitted to hearing loss in severe-profound hearing impaired adults with high frequency hearing losses. Thus, assessing whether hearing aids for this patient population can be adapted to improve speech perception.
The objective of this randomized controlled study was to demonstrate whether fetal hearing can be assessed in utero.
Bone anchored hearing aids provide a hearing solution for patients that are unable to wear traditional air conduction hearing aid solutions. The technology of the devices has developed significantly over the last 510 years and patients are gaining access to their sound processor at a much earlier stage than when first brought onto the market. Despite this the investigators feel there is still room to develop this and with the new abutments with specialised hydroxyapatite coating it is hoped that patients can be loaded with their sound processor in the day of surgery. This study will compare abutment stability between two groups of patients. Those loaded immediately with their sound processor and those loaded traditionally at 2 weeks post operatively. At routine followup appointments patients will have the stability of their abutment checked and the investigators will compare to see if loading earlier had any detrimental effects on osteointegration and the stability of the abutment. Based on the favourable outcomes and high stability record for the BA400 it is anticipated that the time to processor fitting may be further reduced, provided favourable bone conditions at the implant site and provided satisfactory soft tissue status at the time of loading. It is hypothesised that loading immediately at the time of surgery is possible with comparable short and long term outcomes when compared to standard loading at 2 weeks
The cochlear implant is a neural prosthesis and has been the gold standard treatment for severe to profound sensorineural hearing loss over several decades. The surgical procedure for cochlear implantation aims to atraumatically insert the electrode array of the cochlear implant into the cochlea. However, due to the location of the cochlea inside the skull, the surgeon is required to create an access from the surface of the temporal bone to the cochlea (inner ear). In conventional methods, this access is acquired by removal of portions of the mastoid bone through a mastoidectomy and posterior tympanotomy. The outcome and success of the conventional procedure varies due to mainly two factors: surgeon skill and subject anatomical variation. To overcome these variables toward a more consistent and less invasive cochlear implantation surgery, the development of robotic and image guided cochlear implantation has taken place. This study primarily aims to explore the performance of robotic cochlear implantation surgery.
In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of the device under investigation on sound perception. This design was shown to be successful in previous studies for the evaluation of sound coding strategies. Furthermore, a within-subject comparison decreases the variance in the results allowing for fewer subjects when the population using the investigational device is not large in general.
