Use to record the interpretation of all measurements of hearing acuity for each ear or both ears if tested simultaneously, and an overall interpretation (or audiological diagnosis). This archetype has been designed to capture hearing threshold determination for air conduction and/or bone conduction (with or without masking) for the following tests: - Pure Tone Audiometry; - Play Audiometry; - Auditory Brainstem Response; and - Visual Reinforcement Orientation Audiometry. All of the data elements are recorded using a single method or protocol. If, during the test, any of the protocol parameters need to be modified, then the subsequent part of the test will need to be recorded within a separate instance of the test data, using the updated protocol parameters."> keywords = <"hearing", "test", "audiogram", "audiometry", "acuity", "threshold", "decibels", "ABR", "VROA", "VRA", "play"> misuse = <"Not to be used for hearing screening assessment - use the OBSERVATION.hearing_screening archetype.
