The sound of silence: Valuing acoustics in heritage conservation

Abstract

This paper explores the reasons behind the omission of historic acoustic values from heritage assessments in Australia. Best practice dictates that all cultural heritage values associated with significant places should be assessed in order to make informed conservation and management decisions. However, the multi-sensory nature of aesthetics has been reframed in guidance documentation in ways that run counter to the primary frame. Conventions that have developed around the way places are assessed also work against comprehensive identification of values. As a result, the consideration of aesthetics in cultural heritage is limited to contemporary visual qualities. Furthermore, because the assessment of historic value takes a diachronic rather than synchronic approach, we have little knowledge of the places past communities valued for the sounds they experienced there. Research into landscape preference and acoustic ecology highlights the importance of identifying the inherent acoustic dimension of places and the role sound plays in developing a sense of place. Two landscape areas in Western Australia's south-west with historic acoustic values, the Boranup Sand Patch and the Lower Reaches of the Blackwood River, illustrate how historic soundscapes can provide insightful contrasts and resonances with contemporary values, and how vulnerable such places are when the sound of place is overlooked in land management policies. © 2008 The Author.
