Acoustic energy

Acoustic energy:

Acoustic energy is the energy carried by sound waves as they travel through a medium like air, water, or solid materials. It is a type of mechanical energy resulting from the vibration of particles in a medium.

Key Points:

Generated by vibration: When an object vibrates (like a guitar string or vocal cords), it creates pressure waves in the surrounding medium — this is sound.

Energy transfer: The sound waves transfer energy through compression and rarefaction of particles in the medium.

Measured in joules (J): Like all forms of energy, acoustic energy is measured in joules.

Related to sound intensity: The louder the sound (greater amplitude), the more acoustic energy it carries.

Examples:

A speaker converting electrical signals into sound waves.

A whale call traveling through ocean water.

A hammer hitting metal, producing a loud clang — that sound carries acoustic energy.
