NettetWhile sound intensity (in W/m 2) is the SI unit, the sound intensity level in decibels (dB) is more relevant for how humans perceive sounds. The way our ears perceive sound … In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with … Se mer In photometry and radiometry intensity has a different meaning: it is the luminous or radiant power per unit solid angle.

In general, if you’re doing moderate-intensity activity, you can talk but not sing during the activity. In general, if you’re doing vigorous-intensity activity, you will not be able to say more than a few words without pausing for a breath. NettetThe SI unit of irradiance is the watt per square metre (W⋅m −2 ). The CGS unit erg per square centimetre per second (erg⋅cm −2 ⋅s −1) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry where such usage leads to confusion with radiant intensity. In astrophysics, irradiance is called radiant flux.
