Evaluation of Speech-in-noise Performance in Cochlear Implant Recipients With a CROS Device on the Contralateral Ear
Summary
Speech understanding in noise remains the greatest challenge for people using cochlear implants, particularly when the speech of interest comes from the side of the head opposite to the implant. Recent findings in hearing technology allow for people to either use a hearing aid or a Contralateral Routing of Signal (CROS) device on the non-implanted ear. Differences in speech understanding may result depending on the device chosen by a person, and these differences may be measureable through speech discrimination measurement methods.
This study intends to determine whether or not a CROS device improves speech perception in noise when the source of the speech of interest originates from the side of the head opposite to the implant.

Medical and Biotech [MESH] Definitions
Hearing Loss, Mixed Conductive-sensorineural
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.
Hearing Loss, Central
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.
Hearing Loss, Sensorineural
Hearing loss resulting from damage to the COCHLEA and the sensorineural elements which lie internally beyond the oval and round windows. These elements include the AUDITORY NERVE and its connections in the BRAINSTEM.
Presbycusis
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, Sudden
Sensorineural hearing loss which develops suddenly over a period of hours or a few days. It varies in severity from mild to total deafness. Sudden deafness can be due to head trauma, vascular diseases, infections, or can appear without obvious cause or warning.
