Sound is a kind of energy that we can hear. It is made when something vibrates. When something vibrates, it makes the air around it vibrate too. These vibrations travel through the air as sound waves.
Sound waves can travel through other materials too, like water and solids. But they travel more slowly through solids than through air.
The pitch of a sound depends on how fast the object is vibrating. If the object vibrates quickly, the sound will be high-pitched. If the object vibrates slowly, the sound will be low-pitched.
The loudness of a sound depends on how much energy is in the sound waves. The more energy in the sound waves, the louder the sound will be.
The sound of the waves crashing on the shore was soothing.
