Auditory perceptual disorders

This study is testing whether a single dose of nicotine gum can reverse age-related hearing problems. Researchers will give 48 healthy non-smokers aged 18-85 either nicotine gum or a placebo and measure their hearing and brain responses. The goal is to see if nicotine can improve…

This study tests whether a one-month treatment combining the allergy drug clemastine fumarate with engineered sound can improve the ability to hear speech in background noise for people aged 45-65 with age-related central auditory processing disorder (CAPD). About 344 participant…

This study tests whether hearing aids can improve daily hearing for veterans who have normal hearing tests but still struggle to understand speech in noisy places. About 142 veterans will either get hearing aids or standard communication advice. The goal is to see if the devices …

Many blast-exposed veterans struggle to hear in noisy places even though their standard hearing tests are normal. This study tests whether a new fitting method called speech-based audiometry (SBA) makes low-gain hearing aids more effective than the usual approach. Eighty veterans…

This study tests whether listening to music can improve hearing and cognitive processing in healthy adults aged 60 and older. Participants are randomly assigned to one of four groups, including music listening with or without attentional prompts, and a non-music comparison. Over …

This study looks at how people with hearing aids perceive the timbre (quality) of sounds and understand complex sound scenes, like music or crowded rooms. Researchers will compare 75 adults aged 60-75 with and without hearing loss. Participants will listen to sounds and rate how …

This study looks at whether trouble processing sounds (called central auditory processing disorder, or CAPD) causes poor sleep in children and teens with autism. Researchers will compare two groups of 100 kids with autism—those with CAPD and those without—using parent surveys and…
