Audiology is the measurement of hearing. 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.  If a hearing loss is present, an audiologist attempts to decide the cause of the problem and proposes to the patient what options (such as hearing aids, cochlear implants, or surgery) may help to restore function.
