A Study to Evaluate Hearing in Young Adults After Exposure to 3.0T MRI with Routine Hearing Protections
Rochester, MN
The purpose of this study is to establish whether exposure to 3.0T MRI acoustic noise can induce temporary or permanent hearing threshold shifts or otoacoustic emissions amplitude shifts in patients using the currently accepted routine hearing protection.

A Study to Design a Questionnaire to Measure the Hearing Handicap for the Pediatric Population
Rochester, MN
The purpose of this proposed study is to design a psychometrically valid measure of hearing handicap for the pediatric population.
-
Study to Compare Middle Ear Mechanics in Individuals with Unilateral Otosclerosis, and Unilateral and Bilateral Cochlear Implant Recipients
Rochester, MN
The purpose of this study is to measure the changes in the middle ear mechanics or the transfer function in cochlear implant recipients and compare those changes with the middle ear transfer function measured in individuals with unilateral otosclerosis.

A Study to Assess the Role of Technology for the Detection of Hearing Loss
Rochester, MN
The purpose of this study is to evaluate available tablet-based technology that can be easily used to screen and monitor patients for the detection of hearing loss in a quiet, clinic setting.
-
Study of Auditory Function through Intra- and Post-operative Measurements
Rochester, MN
The purpose of this study is to determine if electrocochleography (ECochG) measurements performed during cochlear implant surgery can be used to monitor cochlear structures and minimize electrode insertion trauma.

Role of Sound Source Location on Directional Microphone Benefit in Adult Cochlear Implant Recipients
Rochester, MN
The purpose of this study is to evaluate how the benefit obtained from using a directional microphone like StereoZoom in noise varies with location of the speech source (functional directionality).
-
A Study of Speech Perception for Children with Cochlear Implants
Rochester, MN
The purpose of this study is to determine whether speech recognition in noise can be improved by the addition of a special listening program to the sound processor. Thus we propose to assess speech perception in noise for pediatric cochlear implant patients using both their everyday listening program as well an autosensitivity program.

A Study to Determine the Feasibility of Doppler Ultrasound of Large Arterial Systems of the Brain as Vascular Involvement Markers in Presbyacusis and Presbyvestibulopathy
Jacksonville, FL
The purpose of this study is to benchmark the feasibility of carotid artery biomechanical analysis and vertebral-basilar Transcranial Doppler (TCD) as markers of vascular involvement in presbyacusis and presbyvestibulopathy.

Utilizing the Bone Anchored Hearing Aid (BAHA) Anchor to Conduct Hearing Tests with the Electrical Hearing Audiometer
Scottsdale/Phoenix, AZ
The purpose if this study is to determine if an electrical audiometer provides the same, better or poorer evaluation of the hearing in patients with a Bone Anchor.
-
A Study to Evaluate Electrophysiological Measurements in Cochlear Implant Patients
Rochester, MN
The purpose of this study is to perform electrophysiological (inner ear) measurements to assess hearing function in cochlear implant patients.
