The Sound Intensity Calculator is a physics-based tool that calculates the intensity of a sound wave at a given distance from its source. Using the formula I=P4πr2I = \dfrac{P}{4\pi r^2}I=4πr2P​, where I is the sound intensity, P is the sound power in watts, and r is the distance from the source in meters, this calculator instantly finds how much sound energy passes through a unit area.
