As a social species, humans have developed soundscapes that surround, and to some extent circumscribe, their daily existence. The concept of aural heritage, its conceptualization and its management represent a rapidly expanding area of research, covering aspects of both natural and human heritage. However, there have been no contemporary regional or supra-regional studies that examine the nature of sound making in Christian religious settings, nor the extent to which it is still used. This paper presents the results of a survey into the presence of bells and bell ringing practices among five major Christian denominations in New South Wales, and examines to what extent bell ringing is still practiced and what factors may determine any differentiation. In doing so, it provides an objective basis from which to investigate future changes in bell ringing practices, and provides a solid foundation with reference to aural heritage of sound in a religious setting.
