Listen Here! The Science of Sound and Hearing

Swapping ears (c) Dave Ansell

We open our ears to the science of sound and hearing this week with a look at the genetic causes of deafness and how a deaf person's brain decodes sign language. We also hear how auditory illusions can fool you into hearing things that aren't there and meet a sound simulation system that can improve the clarity of railway station announcements and recreate the "cocktail party effect" to help build better hearing aids.
