What is the difference between sound insulation and sound absorption?
Sound insulation is the act to the act of stopping noise transmission of sound moving from one position to another. An example of sound insulation would be to stop traffic noise from coming into a house or apartment. Typical sound insulation materials involve the use of heavy materials such as bricks, concrete or heavy sound insulation panels.
Sound absorption is the ability of a material to absorb the sound energy that impacts its surface and convert that energy into kinetic energy which is then dissipated as heat. Acoustic foam panels, sound deadening foam panels and soundproofing acoustic foam panels are all products which have excellent sound absorption characteristics.
Sound absorption acoustic foam products should not be used to stop noise transmission.
