The term "Sound pressure" is a concept originating from physics and acoustics, referring to the local pressure deviation from the ambient (average, or static) atmospheric pressure, caused by a sound wave. While sound pressure is a fundamental measure in fields such as environmental noise control, audio engineering, and occupational safety, it is not a term directly or inherently used within the core disciplines of finance, investment theory, or market analysis.
Attempts to establish a direct definition, formula, or application of "Sound pressure" as a financial concept within a financial encyclopedia like Diversification.com would constitute a misrepresentation of its nature and purpose. While there are economic studies on the impact of noise pollution (which is quantified using sound pressure levels) on property values or health costs4, 5, 6, and market analyses of the sound level meter industry1, 2, 3, these applications describe the economic aspects surrounding the measurement of sound, rather than defining "Sound pressure" itself as a financial metric or a component of financial theory.
Therefore, it is not possible to create an accurate, relevant, and verifiable encyclopedia-style article about "Sound pressure" within the domain of finance, as specified by the prompt. The term does not belong to a financial category, nor does it have an applicable financial formula or direct interpretation within financial markets.
