There are many objects that have sound energy. Some of these include musical instruments, vocal cords, and even the human body. Each of these objects produces sound when they vibrate. The vibrations cause the air around them to move, which is what we hear as sound.
Musical instruments are a great example of an object that has sound energy. When you pluck a guitar string, it vibrates and causes the air around it to vibrate as well. This vibration is what we hear as the sound of the guitar. Vocal cords also produce sound by vibrating. When you speak, your vocal cords vibrate and cause the air around them to move, which produces sound waves that we can hear.
The human body can also produce sound waves. For example, when you clap your hands, your palms strike each other and create vibrations that travel through the air and create sound waves.
