Blast Exposed Veterans With Auditory Complaints
Hearing ImpairmentHearing Aid FittingThe purpose of this study is to study blast-exposed Veterans who report hearing handicap but show normal or near normal results on standard audiometric testing. The characteristics and nature of their auditory and auditory-related skills will be examined, along with whether coexisting PTSD contributes to the hearing problems of these Veterans. In a preliminary treatment study, a sub-sample of these Veterans will be fitted with mild-gain hearing aids to determine if they benefit from low-level amplification of high-frequency sounds.
Evaluation of a HiRes™ Optima Sound Processing Strategy for the HiResolution™ Bionic Ear
Severe to Profound Hearing Lossin Adult Users of Advanced Bionics HiResolution™ Bionic Ear SystemThe purpose of this study is to compare a new sound processing strategy to the current sound processing strategy.
Clinical Applications for Time-Compressed Speech Tests
Hearing LossThe purpose of this study is to determine the effects of age-related cognitive changes on hearing aid benefit based on hearing aid compression time constants. The hypothesis is that people with poor working memory skills will benefit from slow time constants in hearing aid compression while those with good working memory skills will be able to benefit from more sophisticated compression algorithms with rapid time constants.
Effect of Hearing Aid Labeling on Speech Understanding Measures
Hearing LossNew and experienced hearing aid users will be fit with two hearing devices. One will be labeled as an OTC (Over-The-Counter) device, the other will be labeled as a Prescriptive (i.e. professionally fit) device. Both devices will be generically programmed for a mild to moderate hearing loss. An objective speech in noise test will be completed with both devices.
Quality Control of CE-Certified Phonak Hearing Aids - 2017_13
Hearing LossBilateral Sensorineural1 moreA methodical evaluation of new CE-labelled Phonak Hearing Systems is intended to be conducted on hard of participants with a hearing loss to grant quality control prior to product launch. The aim of the investigation series is to ensure usability, zero-defect overall performance of the new hearing systems as well as maximum benefit for the participant with the devices in comparison to previously outstanding Phonak Hearing Systems.
A Comparative, Controlled, Clinical Investigation and Quality Control of a New Hearing Aid
Hearing LossThe aim of this study is to investigate the performance of the hearing aid under laboratory as well as everyday conditions. In addition, the performance data of the hearing aid are compared with a Bernafon hearing aid already available on the market. The hearing aids are adapted according to the user requirements. The data collected in the study is intended to show that the benefit of the hearing aid being examined is identical or better than the current CE-marked hearing aid. A further aim is to improve the adaptation of the hearing device in such a way that the benefit for people with hearing impairments can be increased.

Benefits of the HiResolution Bionic Ear System in Adults With Asymmetric Hearing Loss
Hearing LossEar Diseases4 moreThe purpose of this feasibility study is to evaluate the benefit of unilateral implantation in adults who have severe to profound sensorineural hearing loss in one ear, and up to moderate sensorineural hearing loss in the other ear (asymmetric hearing loss).
Clinical Survey of Different Abutment Topologies
Conductive Hearing LossUnilateral Partial Deafness1 moreThis study is designed to compare two different surfaces of bone anchored hearing aid abutments in terms of bacterial colonization, inflammatory response and skin reactions.
A Comparison of a New Acoustic Feedback Canceller in Hearing Aids With the Current System
Hearing LossThe Purpose of the study is to show that the performance of the new feedback cancellation system is better than the feedback system used in the currently marketed hearing aids. Speech understanding should not be negatively affected by the new system, ad there should be no consequential artifacts or unwanted noises caused by the new system.
