We are trying to transfer acoustic information to hearing impaired persons through tactile sensation using air-jet stimuli. We focused on psychological tonal impressions given when hearing various sounds, and examined whether these impressions could be given by air-jet stimuli. In order to replace percussion sounds with air-jets, we connected the acoustic characteristics to the parameters of the air-jet stimuli. Relationships between the acoustic characteristics of percussion instruments and the physical characteristics of air-jets have been found by analysis of psychological impressions given when hearing percussion instrument sounds and perceiving air-jet stimuli. As a result, transmitting musical information was possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
