'audiometrist' originates from Modern English, formed from 'audiometry' + the agent suffix '-ist', where 'audiometry' itself is built from Latin 'audīre' meaning 'to hear' and Greek 'metron' meaning 'measure'.

'audiometrist' developed from the 19th–20th century coinage 'audiometer' (a device for measuring hearing), which stems from New Latin/Greek combining forms based on Latin 'audīre' ('to hear') and Greek 'metron' ('measure'); English added the agent suffix '-ist' to form 'audiometrist'.

Initially it referred specifically to someone using an 'audiometer' to measure hearing; over time it has remained largely the same, denoting a professional who performs hearing tests (and in some places provides basic hearing-aid services).
