Hearing loss: etiology, diagnosis and interventions
Keywords:audiology, Hearing loss, Diagnosis, Hearing aids, bone conduction implants, cochlear implants, auditory brainstem implants
Hearing loss is characterized by increasing difficulty in hearing, interpreting and understanding the sounds around us. Although many acousticians are familiar with hearing trauma caused by loud sounds, a significant part of the acoustics community has limited knowledge on how hearing loss is diagnosed, its consequences in everyday life, or the latest innovations in terms of management. This article summarizes the types and degrees of hearing loss, and its impact on quality of life. The main methods of diagnosis (audiometry, tympanometry, acoustic reflex threshold, auditory evoked potentials), treatments (hearing aids, cochlear implants, auditory brainstem implants), and prevention are also discussed to raise awareness of the day-to-day clinical audiology reality to the Canadian acoustic community.
