It records OAEs elicited by transient or distortion product stimuli. Used by otolaryngologists, audiologists, and nurses in clinical settings for hearing screening in infants and adults. Device processes acoustic signals to detect cochlear function; output assists clinicians in identifying potential hearing loss. Benefits include non-invasive, objective assessment of auditory system. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Otoacoustic emission screening device; records transient or distortion product stimuli. Class II device (21 CFR 874.1050). ## Regulatory Identification An audiometer or automated audiometer is an electroacoustic device that produces controlled levels of test tones and signals intended for use in conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
