Zach lives in an apartment building. His downstairs neighbors are noisy at night, which makes it hard for him to sleep. So, Zach lays a thick rug down on his bedroom floor. This reduces the noise Zach hears at night. The rug is doing what to the sound waves?
The rug is absorbing the sound waves
Wave signals that can travel long distances well are what type of wave signals?
Digital Signals
