Sound events can be compared historically and geographically by mapping

Evidence

One possible form of a sound map, made during two different time periods on a “listening walk” around a city block. The different types of sounds are given graphic values according to whether they are soft, medium or loud, and tabulated to show the general activity and intensity. Using this method, it is simple to make comparisons of sound events historically or geographically. — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 887

Categorization

• SEED: The graphic soft-medium-loud tabulation on a listening walk is a low-tech, accessible recording method a beginner can adopt immediately to catalog a soundscape.
• DEFINE: Introduces the concept of a ‘listening walk’ as a formal field method for soundscape study.
• corroborated: 2 independent passages support this claim — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 887
• XREF: connects to: Morphology classifies sound changes over time or space — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 534; Soundwalks use mapped scores to guide attention to specific sounds — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 695; Sound maps are built from repeatable measurement methods — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 884 (+2 more)
