Sound intensity refers to the power carried by sound waves per unit area. It is measured in watts per square meter (W/m²) and indicates how much energy the sound waves transmit through a specific area. Higher sound intensity means louder sounds, 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 further away from the sound source, like a speaker or a musical instrument. Understanding sound intensity helps in various fields, including acoustics and audio engineering.
