Hearing health is shaped by both measurable auditory function and the perceived ability to navigate daily life. To fully understand its complexities, it is essential to integrate objective assessments behavioural tests that quantify hearing acuity and functional performance with subjective reports on how individuals navigate and manage their hearing in everyday life. The Oldenburg Hearing Health Repository (OHHR) has been developed to unite these perspectives, providing a comprehensive dataset on hearing health. Collected between 2013 and 2015 at the Hoerzentrum Oldenburg in collaboration with Hearing4all, OHHR includes data from 581 individuals (aged 18 – 86 years; 255 females; mean age = 67.31 years; SD = 11.93 ) with varying degrees of hearing loss. This publicly accessible dataset combines audiometric tests (Pure Tone Audiometry, Loudness Scaling, Speech in Noise tests) with self-reports on hearing difficulties, lifestyle, technology use, and cognitive assessments (DemTect, Vocabulary size test). By integrating subjective experience with objective measures, OHHR will enable researchers to explore the links between hearing ability, cognition, and quality of life, providing valuable insights to advance precision medicine.

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

The details of the IRB/oversight body that provided approval or exemption for the research described are given below:

Data protection approval for this study was obtained from the Data Protection and Information Security Management Office at Carl von Ossietzky Universitaet Oldenburg (Application Number: DSM-H4A Open Dataset/20241113-0009). All procedures comply with General Data Protection Regulation. Informed consent was collected from participants whose contact information was available (40%). For the remaining 60%, whose pseudonymized data precluded re-contact, a consent waiver was granted by the board. Additionally, a k-anonymity process (k=4) was applied to further minimize re-identification risk prior to data publication. This process is only described here; the manuscript includes information about the k-anonymity procedure and the approval from the data protection officer in the Methods and Technical Validation sections. The local ethics committee at the Carl von Ossietzky Universität Oldenburg reviewed and authorized the data collection

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
