'audiometry' originates from New Latin and Greek, specifically from Latin 'audīre' meaning 'to hear' and Greek 'metron' meaning 'measure'.

'audiometry' was formed by combining the New Latin/Latin element 'audio-' (from Latin 'audīre') with the Greek-derived element '-metry' (from 'metron'); it entered English in the late 19th to early 20th century and the plural form 'audiometries' developed as the regular plural.

Initially it referred specifically to the act or technique of measuring hearing (the measurement process); over time it has come to refer both to the field/practice and to the individual tests/results (hearing tests themselves).
