Explore the difference between volume and pitch as well as what causes them.

Sound Energy

Some ways that sound can be described are by loudness (or intensity) and by pitch. We can relate to loudness, because we often use the volume for our televisions or iPods™ to make the sound louder (more intense) or quieter (less intense). Pitch is a description of how high or low a sound is. Some sounds have a high pitch, like a chirping bird, while some have a low pitch, like a growling dog.

According to the article how is sound energy created?

Answer:

Sound energy is produced when a force causes an object or substance to vibrate. The energy is then transferred through the substance in waves, called sound waves.
