Conceptualising sound making and sound loss in the urban heritage environment.

Human existence is complemented by environmental sounds as by-products of people's activities as well as intentionally generated sounds that allow human society to function, including transport and traffic sounds and notification sounds. The resulting soundscapes surround and permeate people's daily existence. Technological, as well as behavioural change causes some of these sounds to become extinct at the local or universal level. While expressions of human communication through spoken words (language) and song are deemed to be heritage and thus formally collected and documented, there is a general lack of consideration of the heritage potential of anthropogenic environmental sounds. Focussing on examples from the state of NSW (Australia), this paper discusses sound loss in the urban heritage environment and advances two variations of a conceptual framework to assist heritage practitioners in decision-making to assess heritage potential in order to safeguard some of these sounds for the future.
