Types: qudt:QuantityKind

Predicate	Object
`rdf:type`	`qudt:QuantityKind`
`dcterms:description`	Sound intensity or acoustic intensity ($I$) is defined as the sound power $P_a$ per unit area $A$. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
