The study suggests that sound therapy may protect hearing in patients requiring treatment with ototoxic drugs.
Researchers found that consumers are more likely to buy a product from a different location when a pleasant sound draws attention to the item. This effect is attributed to the ability to visually process products presented in the same spatial direction as the auditory signal, making it easier for consumers to make informed decisions.
A study by University of Alberta researcher Deryk Beal found that children who stutter have less grey matter in brain regions responsible for speech production. This discovery highlights the importance of early treatment approaches like those pioneered by the Institute for Stuttering Treatment and Research.
