What is the term for hearing loss in one ear?

Unilateral hearing loss specifically refers to hearing loss that occurs in one ear, as opposed to both. This term emphasizes the asymmetry of the hearing ability between the two ears, highlighting that one ear experiences a deficiency in hearing capabilities while the other does not. Understanding unilateral hearing loss is crucial for diagnosis and treatment, as it can affect sound localization and communication.

The other terms provided address different conditions: asymmetric hearing loss pertains to differences in hearing levels between both ears but doesn't specify if one ear has completely lost hearing. Bilateral hearing loss indicates that both ears are affected, resulting in a decreased hearing ability in each ear. Moderate hearing loss describes a severity level of hearing loss, regardless of whether it is unilateral or bilateral. Thus, the focus on one ear makes unilateral the correct choice.
