Membrane systems incorporating perforated patterns naturally have an acoustic dampening effect because they allow sound waves to enter the ceiling or wall cavity to be absorbed by the materials from which they are made.
For even better comfort, Velaria Systems offers an Enhanced level of acoustic performance by adding sound absorbing material behind the membrane.
