Speech reception thresholds of children and adults with hearing loss, ADHD and CAPD in a virtual acoustic environment

Speech perception and understanding is an essential precondition for successful everyday verbal communication and facilitates social integration. For people suffering either from hearing loss, attention deficit hyperactivity disorder (ADHD), or central auditory processing disorder (CAPD), listening to a conversational partner in presence of distracting talkers might be substantially more difficult compared to normal hearing people, especially under adverse room acoustics. Nowadays, such challenging situations can be effectively simulated through virtual acoustic environments including plausible room acoustic simulations with virtual sound sources representing target and distracting talkers. In this study, a recently developed hybrid binaural reproduction system, extended for hearing aid users by integrating simulated hearing aid signals, has been applied to assess speech perception performance in eight different experimental conditions. These conditions consisted of varying the location of two distractors with respect to a target talker while either sharing the same or a different voice than the target talker to adaptively measure speech reception thresholds under two different reverberation conditions. Experimental results of adults and children both diagnosed with hearing loss and respective normal hearing controls, as well as children with ADHD and CAPD, respectively, are compared in a between-group analysis.
