Да ладно... а в течении какого временного периода? RMS - длительный, без учета АЧХ.
Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.[1] It is defined[2] as "through a surface, the product of the sound pressure, and the component of the particle velocity, at a point on the surface in the direction normal to the surface, integrated over that surface." The SI unit of sound power is the watt (W).[1] It relates to the power of the sound force on a surface enclosing a sound source, in air. For a sound source, unlike sound pressure, sound power is neither room-dependent nor distance-dependent.
