  • Elliot Freeman was a student when he first noticed that he could hear Morse code. Looking out into the dark one evening, he spotted a lighthouse flashing a signal. It turns out Freeman isn't alone. He is one of a group of people who experience a phenomenon called visually evoked auditory response. This form of synaesthesia makes people hear noises when they see certain silent moving images. Now he has carried out the biggest study of the condition so far and found that one-fifth of us seem to experience it. With his colleague Christopher Fassnidge, Freeman, a psychologist at City, University of London, built an online survey that tests for this response. They found that about 22 per cent of the 4000 respondents rated more than half the videos in the test as stimulating clear sounds.
