The perceived auditory environment is an increasingly important part of people s everyday interactive experiences. While sound design is an established discipline in media such as video games and cinema, this is not the case in Human-Computer Interaction (HCI). HCI designers are rarely trained in sound design, and may not make the most effective use of sound in the design of interactions. Even when sound is at the centre of a design it is rarely evaluated to compare the experiences of designers and listeners. This dissertation reports work conducted to develop a way of comparing sound designers intentions for a sound design with the experiences of listeners.
