NCT07216937
Access to affordable and timely hearing healthcare remains a major challenge for many individuals, partly due to the high cost and long turnaround time. This study will explore whether 3D-printed ear tips perform as well as or better than standard ear tips in terms of sound quality, comfort, and fit. It will also compare how long each method takes to make and how much each costs.
NCT05954520
The purpose of this study is to investigate the effect of nonlinear signal processing algorithms on speech perception.
NCT04618315
Satisfaction and benefit from hearing aids fit using two patient self fit methods will be compared against those fit using audiology-based best practices. Individuals between the ages of 50 and 79 years of age will be randomly assigned to one of three fitting methods. Benefit and satisfaction will be evaluated six weeks and six months after the initial fitting.

Tinnitus - defined as ringing, humming, or other sounds in the ears or head - is a very common problem for Veterans. Hearing aids that deliver low-level amplification are being used by audiologists to help people with tinnitus who also have normal hearing. However, there is a lack of research evidence showing that this practice is effective. Despite this fact, the practice clearly is spreading. Reports from audiologists in the field as well as research presentations refer to hearing aids being used in this way. Use of hearing aids has been shown to reduce distress from tinnitus for people with hearing loss. Additionally, the use of external sound to help reduce the impact of tinnitus has been shown to be effective. There is clearly a gap in the research regarding the use of hearing aids as a therapeutic method to manage tinnitus when hearing is considered normal. This study will obtain pilot data evaluating people with normal hearing and bothersome tinnitus to find out whether low-level amplification through hearing aids may provide benefit.
NCT04840277
Many hearing aid users experience substantial communication difficulties that may affect their participation in daily life situations negatively. One of the reasons for experiencing remaining problems could be due to unrealistic expectations, another reason could be that the hearing aid is not well adjusted or that the hearing aid user didn't got sufficient support and follow-up from the audiologist. The purpose of this project is to offer remote hearing aid adjustment as an additional support for experienced hearing aid users.
