Assessing Listening Effort at Different Signal-to-noise Ratios in Bone-anchored Users

2020-01-30 14:40:46 | BioPortfolio

Summary

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.

Description

Pupil dilation can be used as an objective indicator of listening effort during the execution of a task. The aim is to compare listening effort with different settings (OpenSound Navigator ON and OFF) of Ponto 4, the sound processor released by Oticon Medical AB in June 2019, in listening scenarios that differ in complexity. The study consists of three visits of about two hours each in duration, during which the patients will perform a speech-in-noise task where the listening task varies in difficulty (i.e., in terms of signal-to-noise ratio, SNR). Pupil dilation will be recorded during the listening task as an indicator of listening effort. The patients will also use Ponto 4, instead of their own Ponto device, during a field-trial period of three months in between visit 2 and 3. Subjective evaluations of Ponto 4 will be performed via three questionnaires, one regarding self-reported performance in everyday life, one regarding work-related fatigue, and one regarding overall sound processor preference (Ponto 4 vs. patient's own device). All these outcome measures are non-invasive measurements. This is a post market study and all products used are CE marked and used in clinical practice worldwide.

Medical and Biotech [MESH] Definitions

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.
