Hearing loss, affecting about 5% of the world's population, is the partial or complete inability to perceive sounds. Hearing aids (HAs) can help mitigate this problem. However, HAs require fine-tuning, usually done through simple tests in the lab or after in-field trials by users in daily life, involving several audiological visits to achieve a satisfactory fit. Using augmented reality and immersive audio to recreate daily auditory scenarios in the lab can expedite the fitting of HAs. However, establishing such advanced laboratories is expensive and complex. This study aims to validate a low-cost immersive audiovisual laboratory suitable for hospitals and clinics, namely the Audio Space Lab (ASL) at the Polytechnic University of Turin, Italy.
