BBC reports a new study from Oxford University researchers:

“We are all capable of “hearing” shapes and sizes and perhaps even “tasting” sounds, according to researchers.

“This blending of sensory experiences, or synaesthesia, they say, influences our perception and helps us make sense of a jumble of simultaneous sensations. (Emphasis added)

“Oxford University scientists found that people associate lower-pitched sounds with larger and more rounded shapes.”

Researchers say, though, that relatively few people actually do use their senses this way, we all could.
