liminal: The Lost Frequency
In September 2008 liminal were awarded a grant from the Wellcome Trust for the research phase of their project Tranquillity is a State of Mind: Listening Aids for a Listening Impaired Society. Working in partnership with Sustrans, the sustainable transport charity, liminal brought together a research team comprising two acousticians, a computational neuroscientist and a clinical audiologist in order to develop a proposal for what we are describing as a ‘listening aid’ – a device that might encourage the listener to contemplate the act of listening itself.

Of key concern in the development of the project was how an intervention on a site can create such a reflexive listening experience. Implicit in our research (and a driver to the constitution of our research team) was a desire to explore the relationship between unwanted sound in the ear (tinnitus) and unwanted sound in the environment. By getting a better understanding of the physiological and neurological causes of tinnitus and learning about audiological techniques used for its treatment, we hoped to be in a better position to understand the link between our physical response to unwanted sound and our environment.

The research was undertaken over a period from September 2008 to end of May 2010 as part of the Wellcome Trust funded research project Tranquillity is a State of Mind: Listening Aids for a Listening Impaired Society.
