How Can Sounds Be Loud or Soft?

Sound Waves are what sound travels in! They are little vibrations of air that travel through a medium or a material that it is travelling through. Sound Waves are why you can hear a jackhammer or my podcast!! Sound Waves work like this: First, an object or person has to make a sound. A sound is made by an object vibrating back and forth. When the object vibrates, the air around it starts to move. The molecules of air bump into each other. This causes a wave of air molecules. This wave continues until it reaches your ear!! This is how sound waves work! Sounds travel better through materials or mediums that are very dense. That means that the atoms are packed together tightly.

The volume of a sound depends on how tall the sound waves are. If the sound waves are tall, the sound is loud. If the sound wave is short, the volume is lower. Try to pick out certain sounds that are loud or soft!
