听力学是一门医学专科，听力学包含了基础听力学、一般听力学、幼儿听力学、职业听力学、听力检查。

• 基础听力学为听觉声学之探讨。
• 一般听力学之下可分为听觉生理、听觉病理两大类，主要是探讨听觉的生理机转以及病理变化。
• 幼儿听力学是专门探讨幼儿听觉生理及幼儿听觉病理相关问题，因幼儿在生理及病理方面与成人有所差异，所以特别另外提出探讨。
• 职业听力学为探讨职业对于听力损害。
• 听力检查为检查听力时的技巧以及仪器，并且因幼儿与成人的不同，所以分为幼儿听力检查以及一般听力检查。

Audiology (from Latin audīre, "to hear"; and from Greek -λογία, -logia) is a branch of science that studies hearing, balance, and related disorders. Its practitioners, who treat those with hearing loss and proactively prevent related damage are audiologists. Employing various testing strategies (e.g. hearing tests, otoacoustic emission measurements, videonystagmography, and electrophysiologic tests), audiology aims to determine whether someone can hear within the normal range, and if not, which portions of hearing (high, middle, or low frequencies) are affected and to what degree. If an audiologist determines that a hearing loss or vestibular abnormality is present he or she will provide recommendations to a patient as to what options (e.g. hearing aid, cochlear implants, appropriate medical referrals) may be of assistance.
