Explanation:

• Absorption: When a sound wave is absorbed by a medium, its energy is taken in by the medium, not just slowed.
• Echo: An echo is a reflected sound wave that we hear after a delay.
• Reflection: Reflection is when a sound wave bounces off a surface.
• Transmission: When a sound wave passes through a new medium, it can be slowed down as it interacts with the particles of the new medium.

Transmission
