What happens to sound energy when we speak?

In order to speak, we move air past our vocal cords, which makes them vibrate. The vocal cords must be in good shape for speech to sound clear and loud. Air being let out of a balloon mimics how air passes through the vocal cords to produce sound.

Where does the energy of a sound wave go?

Solids, liquids, and gases all transmit sound as energy waves. Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate. That energy moves through the substance in waves. Those sound waves are called kinetic mechanical energy.

How does the sound travel?

Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. Sound can move through the air, water, or solids, as long as there are particles to bounce off of.

What happens when the sound stops?

Sound waves stop forward motion, when they undergo total reflection or absorption.

How is sound energy stored?

Sound is a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid. Therefore, the medium acts as storage for both potential and kinetic energy.

Can sound be converted into energy?

Noise (sound) energy can be converted into viable source of electric power by using a suitable transducer. The vibrations created by noise can be converted into electrical energy through the principle of electromagnetic induction.

When we speak it requires energy, some of this energy goes into the sound waves—as the sound waves travel through the air, it loses its energy and the volume of sound decreases. The sound waves may hit some solid object and loses some more energy and some these waves bounce back.

What happens to the energy in sound waves when they are destroyed?

Energy cannot be destroyed but information can. To answer your question the energy in sound waves goes into warming the air and other materials affected by the sound waves. Mostly the walls ceiling and floor. Outside into air and ground.

How does sound energy transfer from one place to another?

The energy gets absorbed by the materials that the sound wave interacts with—the ground, the walls, even the air—and gets converted into random vibrations of the molecules in the material. That transfers to the surroundings as heat until thermal equilibrium is reached.

How does speaking affect the entropy of the universe?

When you speak or a create noise, the energy in the sound waves is dispered in the room or environment you are in. You are contributing to the entropy of the universe. The energy will be transformed in something that is useful to you (speaking) into spreading of this energy over more and more molecules with less and less impact to your environment.
