Beyond mere noise: how we perceive the world through soundscapes
In short: We often think of noise as something to be silenced, but the true soundscape is more than just volume. It is a complex, human-centered perception of our acoustic environment, blending the whispers of nature with the mechanical hum of civilization to create a unique sense of place.
While often attributed to composer R. Murray Schafer, the term 'soundscape' likely originated with city planner Michael Southworth, who used it in a 196/67 paper regarding Boston's sonic environment. Unlike the broader 'acoustic environment'—which encompasses all physical sound resources, including inaudible vibrations like bat echolocation—a soundscape specifically refers to how humans perceive and understand these sounds in context. This distinction was standardized by the ISO in 2014.
Ecologists like Bernie Krause have categorized these environments into three distinct layers: geophony (non-biological natural sounds like wind or waves), biophony (non-human biological sounds such as animal vocalizations), and anthropophony (human-generated signatures). Within the anthropophony, we find 'controlled sound,' such as music and language, alongside the mechanical noise of industrial technology. When these layers are disrupted or obscured by excessive noise, it results in noise pollution.
The quality of a soundscape can be measured by its clarity. In a 'hi-fi' landscape, such as a rural area, a high signal-to-noise ratio allows discrete sounds to be heard clearly from both near and far. Conversely, 'lo-fi' landscapes, typical of dense cities, are characterized by a broad-band of noise that obscures perspective, forcing listeners to focus only on immediate, often amplified, encounters. This field now informs urban design, where architects use 'masking'—such as water features—to mitigate unwanted traffic noise and improve psychological well-being.
