You hear sounds all the time - some are high screeches and some are low rumbles; some are loud bangs and some are soft whispers. Find out how you use your sense of hearing to listen to all these incredible sounds. Discover how people who can't hear use sign language to communicate, how a bat uses echoes to locate things around it and how some minibeasts hear things through their legs. Large, fascinating photographs help to bring the simple text to life and a colourful diagram clearly explains how humans are able to hear things. Two pages of activities encourage children to interact with the world around them by using their senses.
