Acoustic Depth

Acoustic depth is an elusive indicator that touches the world of emergencies, or perceptual focus, in a peculiar way. The realm in which these forms of recognition operate indeed links media theory to perception theory and aesthetic reflection. Expressions such as acoustic scene, sound depth or sharpness, or acoustic image when discussing the receptive forms of various microphone models, are just a few cases where imaginative synthesis translates the sense of phenomena arising from the resistance of sensory properties to the structures of linguistic formalization. The language of media is full of these references, which seem to refer to a common sense that emerges in the differentiation of perceptual channels, but is rarely made explicit in a clear manner. To understand acoustic depht’s nature, we can use the concept of emergence: every time we hear a sound, that acoustic process is always surrounded by a myriad of small sounds that interact with it.

The notion of emergence can be applied to anything present in the surrounding environment. It can be applied to any configuration that breaks the homogeneity of a perceptual field. So, we can analyze the complexity of this synthetic formation by tracing it back to increasingly simpler synthetic planes. When talking about composition, synthesis, and association, it has already the results of compositional operations and which provided the ultimate or primary material – either term suffices, depending on the direction we choose to take.

These are essential factors in spatial orientation processes, but they are structurally opaque: we’ll work on three examples taken from classical music, ethnomusicology, and hearing aids.
