Active clinical trials for "Hearing Loss"

The purpose of this study is to find out whether the High Frequency Digit Triplet test can be used to screen patients with cystic fibrosis for hearing loss in conditions of health and pulmonary exacerbation. It is also designed to find out the youngest age at which a child can perform the test, the prevalence of hearing loss in a CF population and the prevalence of genetic mutations known to be associated with hearing loss in the same population.

The specific aim of this research is to evaluate the performance, effectiveness, and long-term training benefits of a formal hearing protection fit testing program. This study may provide preliminary evidence on the benefits of direct education/training combined with a formal hearing protection device (HPD) fit testing on HPD fittings on United States Air Force (USAF) employees. Currently, Public Health provides informal, subjective training to employees; this practice may be altered by the results of this study.

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

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.

Obesity may directly or indirectly lead to hearing loss

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

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.

A sound dosimeter will be used to measure noise level to which a population of head and neck patients on the otolaryngology ward are exposed to. The device is the EXTECH 407764 type II sound level meter (IEC 651 RS232). The device will be configured to OSHA and ISO standards, and calibration confirmed in a sound booth with a sound level calibrator. The dosimeter captures A-weighted sound levels between 30 and 130 dB. Specifically, participants included in the study will be head and neck cancer patients on the otolaryngology floor at VG site. Measurements will be taken three times a day at random intervals. Each measurement will be taken in a similar manner. The dosimeter will be placed on the head side of the bed at the level of patient's ear one inch away from the ear and kept there for ten seconds to get a representative level. The overall measurements will be averaged (Leq) for statistical analysis. Investigators will randomly select 50% of the patients and give them protective ear plugs to be used while the participants are inpatients, and the other 50% will not provide them with ear plugs (like what is being done now). Investigators will obtain a baseline hearing test prior to admission and 7 days after admission and then a repeat hearing test at 3 weeks after discharge. The goal is to establish if there is a temporary or a permanent threshold shift.
