Objective:
Common hearing assessments often overlook key aspects of hearing loss and its impact on daily-life. This study evaluates a broad dataset of audiological and functional measures by applying the World Health Organization's International Classification of Functioning, Disability, and Health (ICF) Core Sets for Hearing Loss. The aim is to clarify which aspects of hearing loss-related functioning are represented in the dataset and which aspects are not addressed, thereby supporting appropriate interpretation and use of the data in clinical and research contexts.
Design:
The dataset includes results from otoscopy, pure-tone audiometry, a self-reported hearing and functioning questionnaire (HEAR-COMMAND Tool), speech intelligibility tests (Göttinger Sentence Test, GöSA and Oldenburger Sentence Test, OLSA), listening effort evaluation (Adaptive Categorical Listening Effort Scaling, ACALES), loudness perception assessments (Loudness Validation Method and Adaptive Categorical Loudness Scaling), a multi-talker conversation task (Concurrent Oldenburger Sentence Test, CCOLSA), coupler measurements, in-situ recordings, tone-in-noise perception, and the Dialogue Picture Task (DIAPIX). Using the ICF linking rules, all measures, performed on 76 participants, were systematically mapped to ICF categories.
Results:
For the brief CSHL, the dataset addressed 92.5% of the categories, missing only brain and inner ear structures. For the comprehensive CSHL, the dataset addressed 50.4% of the categories. This included 81.8% of Body Functions, 40% of Body Structures, 59.5% of Activities and Participation, and 29.1% of Environmental Factors.
Conclusion:
The results demonstrate that the dataset captures many key aspects of hearing loss and its consequences while also clarifying which areas of functioning are not addressed. By applying the ICF framework as a standardized reference, this study provides guidance for the transparent interpretation and appropriate use of the dataset in clinical and research settings, while enabling the creation of detailed profiles of an individual's hearing loss that are relevant for modeling speech intelligibility and listening effort.
