The purpose of this study is to evaluate the benefit of bilateral implantation with bone-anchored hearing systems (BAHS), in terms of sound localization abilities, as well as auditory working memory. The hypothesis is that the use of two BAHS (bilateral condition) will not only improve localization abilities, but it will also increase the ability to retain words in working memory, compared to performance with only one BAHS (unilateral condition).
The patients included in this study are adult patients with a bilateral conductive or mixed hearing loss, that are already bilaterally implanted with two percutaneous bone-anchored devices (BAHS). The study consists of two visits. At visit 1, the patients are fitted unilaterally and bilaterally with the investigational device (Ponto 3 SuperPower). After fitting, the patients perform a test of spatial resolution (minimum audible angle, visit 1) and an auditory working memory test (visit 2). These two outcome measures are conducted in the laboratory using the Ponto 3 SuperPower unilaterally and bilaterally. Additionally, the patients fill in a questionnaire (SSQ12) to report perceived performance in their everyday life with their own devices. This is a post market study and all products used are CE marked and used in clinical practice worldwide.

Main objectives - The first main objective is to evaluate the non-inferiority of the ADHEAR system compared to the PONTO 3 SUPERPOWER softband system in terms of average tonal gai...
The purpose of this study is to assess listening effort during a speech-in-noise task in bone-anchored hearing systems (BAHS) users via pupillometry.
This study is designed to investigate the benefits of the hearing aid in the laboratory and in daily life when fitted with two different methods. Subjective and objective evaluations will ...
This prospective, multi-center study funded by Oticon Medical AB will be conducted at six clinical sites in North America. Patients with a hearing loss and that are already planned for tre...
Currently, the fitting of hearing aids is using a computer interface that allows to adjust the gain and compression of acoustic amplification. This adjustment is made face to face, patient...
Purpose This clinical focus article describes considerations for recommending assistive hearing technology to infants and young children who have mild bilateral or unilateral hearing loss. These condi...
The role of bilateral bone conduction amplification in patients with bilateral conductive hearing loss is unclear because cranial attenuation is usually considered negligible, and both cochleae can be...
Purpose Because of uncertainty about the level of hearing where hearing aids should be provided to children, the goal of the current study was to develop audibility-based hearing aid candidacy criteri...
Purpose This study investigated progressive hearing loss in a cohort of children who were identified with permanent mild bilateral hearing loss. Method This population-based study included 207 childre...
Purpose Previous evidence supports benefits of bilateral hearing aids, relative to unilateral hearing aid use, in laboratory environments using audio-only (AO) stimuli and relatively simple tasks. The...
Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
Partial hearing loss in both ears.
Gradual bilateral hearing loss associated with aging that is due to progressive degeneration of cochlear structures and central auditory pathways. Hearing loss usually begins with the high frequencies then progresses to sounds of middle and low frequencies.
Hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 dB. The hearing loss is often in the frequency range 4000-6000 hertz.
Hearing loss due to damage or impairment of both the conductive elements (HEARING LOSS, CONDUCTIVE) and the sensorineural elements (HEARING LOSS, SENSORINEURAL) of the ear.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
