Deafness gives Bella a new perspective on city life - a fresh way of experiencing the world and the people around her.
In 1997, Bella Bathurst began to go deaf at the age of 28. Within a few months, she had lost half her hearing, and the rest was slipping away. She wasn't just missing punchlines, she was missing most of the conversation - and all of the jokes. For the next twelve years deafness shaped her life.
Sound draws on this experience, exploring the practical and emotional impact of losing your hearing, and what it teaches you about listening and silence, music and noise.
Today, deafness dramatically changes Bella's experience of the busy streets of London. But, as she sits on the top deck of a bus, she realises that while she can't hear the sounds of the crowd, she has a new way to read the interactions she sees on the street below.
