ARCHETYPE IDopenEHR-EHR-OBSERVATION.categorical_loudness_scaling.v0
ConceptCategorical loudness scaling
DescriptionCategorical loudness scaling
UseUse to record responses to loudness scaling procedures with or without using hearing aids.
Misuse Not to be used for hearing threshold, audiogram or speech understanding assessment Not to be used to record other auditory assessments such as: - Behavioural Observation Audiometry (BOA); - Auditory Brainstem Response (ABR) for diagnostic purposes - Transient Evoked Otoacoustic Emission (TEOAE); and - Distortion Product Otoacoustic Emission (DPOAE). These assessments need to be recorded in specific archetypes for the purpose.
PurposeTo record responses to loudness scaling tests and calculate respective individual loudness growth functions.
