What is the difference between sound absorption and sound insulation?

Sound absorption improves acoustic comfort within a room by reducing reflections and reverberation. When sound hits an absorptive surface, such as an acoustic ceiling tile or wall panel, some of the sound energy is absorbed. This reduces the build-up of sound, making spaces feel calmer, clearer, and more comfortable. 

Sound insulation prevents noise transmission between rooms or across building elements. While several types of sound insulation exist, Rockfon products mostly focus on two main categories:  

Direct sound insulation: 

blocks noise traveling directly through structural elements such as walls and ceilings.  

Room-to-room sound insulation:

Prevents indirect sound transmission between adjacent spaces via shared structures, for example noise passing above a suspended ceiling into a neighbouring room.  

 To meet all acoustic requirements, Rockfon offers both sound absorbing and sound insulating solutions.
