The method employed to improve the sound insulation between two areas depends on the situation. For this reason, the advice of a competent person should be sought at an early stage. Following are general guidelines to consider in improving sound insulation.

In general, applying sound absorbing treatments will not greatly improve insulation conditions. Typically, blocking the transmission of sound by introducing barriers is the most beneficial route to take. Such a barrier could take the form of a barrier blocking the line of sight between a busy highway and house or a massive wall between apartment units. Common culprits in areas where sound insulation is an issue include windows, doors, ceiling plenums, and lightweight roofs.
