"Theatre is a strange world where we are often trying to bring life to imaginary places, in distant eras. The audience are often complicit with us, ignoring that we’re sat in an auditorium with traffic going by outside, imagining that we’re in, for example a forest in the 16th century listening to Macbeth talk to a trio of witches. My job encompasses all the aural elements of that suspension of disbelief. And a lot of it involves not just the creation of sounds and a sound system, but also an understanding of how that sound will be heard and perceived by the audience, and how to use that knowledge to take them on the journey of the story."
