Bilateral hearing loss refers to the presence of hearing impairment in both ears. This type of hearing loss can be either symmetrical, where the degree and configuration of hearing loss are similar in both ears, or asymmetrical, where there are differences between the ears in terms of severity, configuration, or type of hearing loss. Bilateral hearing loss can result from various causes, including genetic factors, exposure to loud noise, aging, medical conditions, or trauma. Managing bilateral hearing loss often involves hearing aids or other assistive devices to improve overall auditory function and enhance the ability to communicate effectively in various environments. The treatment approach may vary depending on the specific characteristics and causes of the hearing loss in each ear.
