“We are finding that sound is affecting not just the perception of our body shape but our physical capabilities. Understand these sounds and we could change our feelings in a positive way.”
The phenomenon works because of a recently discovered theory of how the brain functions called ‘predictive coding.’
The brain is constantly making judgements based on the likelihood of something happening based on past experiences. It is how we know whether there is enough space between cars to cross a busy road.
However, giving the brain new sensory clues will change perception. Sound is an important sense which helps us judge the world around us.
