The science and practice of measuring hearing ability using specialized equipment to test how well and how loudly a person can hear sounds.
From Latin 'audire' (to hear) + Greek 'metria' (the practice of measuring). The term combines these roots to describe the field devoted to quantifying auditory perception.
Audiometry emerged in the 1920s alongside radio technology—the same vacuum tubes used to amplify radio signals helped create the first electronic sound generators for hearing tests, connecting entertainment technology to medical diagnostics.
