Good acoustic performance is a requirement for nearly all types of buildings, but is particularly important for residential buildings, schools and hospitals.
Sound can travel between rooms by two routes; either directly through the separating wall and around the wall through any adjacent elements.
Acoustic insulation for both routes is managed by different features: mass, the total mass per unit area; and isolation separating any different layers within the element.
