Sound intensity refers to the power carried by sound waves per unit area, typically measured in watts per square meter (W/m²). It indicates how much energy the sound wave transmits through a specific area over time. Higher sound intensity means a louder sound, while lower intensity corresponds to quieter sounds. The intensity of sound is influenced by factors such as distance from the source and the medium through which it travels. For example, sound intensity decreases as you move away from the source, like a speaker or musical instrument. Understanding sound intensity helps in various fields, including acoustics and audio engineering.
