What soaks up energy?

Materials that soak up energy include:

* Insulators: Insulators are materials that do not conduct heat or electricity well. They are used to keep heat or cold from escaping from a space. Examples of insulators include fiberglass, cellulose, and polystyrene foam.

* Absorbers: Absorbers are materials that absorb sound or light waves. They are used to reduce noise or glare. Examples of absorbers include acoustic panels, curtains, and vegetation.

* Dampers: Dampers are devices that absorb shock or vibration. They are used to protect equipment from damage or to reduce noise. Examples of dampers include shock absorbers, springs, and vibration isolators.
