'This is a Voice' was an exhibition at the Wellcome Collection, London, that examined the material quality of the voice through a number of audio installations. 

The exhibition brought together a wide range of works by contemporary artists and vocalists including Matthew Herbert, Imogen Stidworthy and Joan La Barbara, punctuated by paintings, manuscripts, medical illustrations and anthropological research. 

Conceived as an acoustic journey, the exhibition space needed be physically open to allow visitors to move freely.  The challenge was combining the contrasting acoustic design aspirations of generating a coherent exhibition soundscape in an open space, with measures to control excess sound-spill between the different exhibits.
