Conceptcommon_audiological_functional_parameters
DescriptionA set of functional parameters that provides an abstract description of all relevant functional aspects of the human auditory system, with interpretation ranging from "normal" (0) to "maximally impaired" (1). The list of possible functional aspects corresponds to the definition of Buhl et al. (2019).
UseUse to summarize data from audiological tests that were performed with humans in hearing aid acoustician, ENT physician, or research scenarios. CAFPAs can be estimated by human experts or predicted by machine learning algorithms.
MisuseNot to be used to directly save measurement results (corresponding to a test corresponding to the respective functional parameter).
PurposeTo summarize data from different audiological tests (as performed in a certain clinic/database) in an independent and abstract representation of the human auditory system. Thereby, the CAFPAs are independent from the exact used tests for characterizing certain aspects of hearing loss in different clinical or research databases, and can be used to compare data from different databases.
