Abstract
Smartphone-based listening tests have expanded the reach of traditional laboratory-based assessments, offering convenient, low-threshold access to hearing evaluations and early diagnostics of hearing loss. Despite these advantages, such tests often suffer from a lack of controlled environments, absence of test supervisors, uncalibrated devices, and inattentive participants, resulting in potential inaccuracies and unreliable outcomes. This thesis explores the potential of smartphone-based hearing tests as accessible, scalable tools for audiological assessment outside clinical environments. Focusing on pure-tone audiometry and categorical loudness scaling, it examines how participant attention, audiologist supervision, and ambient noise affect test outcomes. The findings reveal that when users remain attentive and background noise is minimized, unsupervised mobile-based assessments yield results comparable to standard clinical procedures. These insights highlight the validity, reliability, and efficiency of smartphone-based hearing tests and support their broader use in early hearing loss detection and hearing care delivery, particularly in underserved settings.

Smartphone-basierte Hörtests haben den Umfang herkömmlicher, laborbasierter Hörtests erheblich erweitert und bieten den Teilnehmern einfachen Zugang zur Bewertung ihres Hörvermögens und somit frühen Diagnosen von Hörverlust. Trotz dieser Vorteile leiden solche Tests oft unkontrollierten Umgebungen, fehlenden Testaufsichten, unkalibrierten Geräten und unaufmerksamen Teilnehmern, was zu Ungenauigkeiten und unzuverlässigen Ergebnissen führen kann.
