Active clinical trials for "Hearing Loss"

Within the course of this study, a signal processing feature has been developed at Ecole Polytechnique Fédérale de Lausanne (EPFL), in collaboration with Sonova AG, in order to enhance the listening experience with remote microphone systems. In particular, the developed feature is supposed to improve the so-called audio-visual fusion, i.e. the fact to perceive the sound as coming from the physical location of the source. One of the main goals of the present study is to evaluate the extent to which this feature reaches that objective.

The investigators aim to investigate the effect of operating room noise on anesthetist hearing

Study to accumulate post-market clinical evidence for the safety and effectiveness of the Sophono Alpha 2 and Alpha 2 MPO systems in subjects diagnosed with conductive hearing loss, single-sided deafness and mixed hearing loss who currently have or have had the Sophono implant.

Despite being effective, the majority of people who would benefit from using hearing aids do not access them. For those who do obtain hearing aids, around 20% do not wear them regularly. People often do not use their hearing aids because they continue to experience difficulties when listening to and understanding speech in noisy situations. Conventional hearing aids must be programmed and adjusted by a trained audiologist with specialist equipment and therefore provide limited user-control over the hearing aid's functionality. In comparison to conventional hearing aids, Smartphone-connected hearing aids enable patients to adjust their programmes themselves in different situations using a Smartphone application. Smartphone-connectivity can supplement clinical practices, as patients can adjust their hearing aids without the need to visit the clinic. This has the potential to empower patients to be actively involved in their own hearing healthcare. A systematic review assessing the effectiveness of alternative listening devices showed that there is no published high-quality research assessing the clinical effectiveness of Smartphone-connected hearing aids. Furthermore, a usability research study has shown that patients want to personalise and adjust their own HA programmes to meet their individual needs. Having carried out the early development work, the next step would be to carry out a study to evaluate smartphone-connected hearing aids, in accordance with the MRC guidelines on developing and evaluating complex interventions. This study will assess the benefits of a smartphone application, eAdjust that has been developed for use with Phonak Audeo B90-Direct hearing aids. The eAdjust app connects to the hearing aid via Bluetooth, and enables hearing aid users to fine-tune their hearing aids via their smartphone. The benefits of the eAdjust app will be assessed in the real-world as well as in the laboratory. A mixed methods approach will be taken, using both behavioural and patient reported outcomes.

The roles of thrombophilia and cardiovascular risk factors in sudden sensorineural hearing loss (SSNHL) remain controversial. Cochlear micro-thrombosis has been hypothesized as a possible pathogenic mechanism of SSNHL. The objective was thus to measure the levels of markers of macrovascular thrombosis and microvascular risk factors

assess the effect of dental educational program on oral hygiene among institutionalized hearing impaired and mute children in Cairo, Egypt.

Obesity may directly or indirectly lead to hearing loss

The purpose of this study, which contains a series of successive study parts, is to methodically evaluate Phonak Hearing Systems on hard of hearing participants to grant quality control prior to each product launch.

In this study, the investigators have aimed to investigate whether GDM is a risk factor for hearing impairment in newborns. To the investigators knowledge, this study is the first prospective, controlled study on this subject.

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).
