Designed by Selina Botham, the Widex hearing garden includes an interactive "listening wall", water features and sculpture.
Botham was inspired to help people appreciate the sounds around them.
She explained: "Being in a garden, immersed in a full sensory experience, is one of the great pleasures of life. I hope my design will help people to appreciate and celebrate those everyday sounds that are so important in our enjoyment of the world around us."
The Hampton Court show takes place on 8-13 July.
