AUDITORY BRAINSTEM PROCESSING OF COMPLEX SPEECH SOUNDS IN YOUNGER AND OLDER ADULTS USING SEABR - A REVIEW
Author: Muhammed Ayas, Rajashekhar B.
The ability of the human auditory system to process the acoustic information from peripheral auditory centres to the auditory centres in the brain is integral for understanding speech and non speech sounds. Age is a critical factor that most often impairs the temporal processing in human population. Due to the decline in temporal precision in the aging auditory system, difficulty in speech understanding was expressed by many older individuals.Difficulty in discriminating speech was perhaps one of the most critical forms that hearing loss can have in person’s life. There were various techniques and procedures used to assess the auditory processing in this group of individuals. In recent times, the focus lies on using Speech Evoked Auditory Brainstem Responses (SEABR) to unravel complex speech processing at the brainstem level in children and adults. This article reviews the various studies done using SEABR to understand the brainstem timing changes in various age groups.
Keywords: Speech evoked auditory brainstem response (SEABR), Temporal processing, Onset responses, Frequency following response
