Which term refers to the study of hearing disorders?

Audiology is the correct answer as it specifically pertains to the study of hearing disorders and the assessment and treatment of auditory and balance issues. This field encompasses various aspects of hearing, including the diagnosis and rehabilitation of hearing loss, the fitting of hearing aids, and the study of auditory pathways.

In contrast, otology is a branch of medicine dealing with ear diseases, but it does not solely focus on hearing; it includes broader ear health concerns. Labyrinthitis refers to inflammation of the inner ear structures involved in balance and hearing, which is a specific condition rather than a field of study. Myringoplasty is a surgical procedure aimed at repairing the eardrum, which also does not relate to the study of hearing disorders in a broader sense. Thus, audiology is the term that most accurately represents the study of hearing disorders.
