Windows are usually the weakest part of a residence in terms of exterior-to-interior noise reduction. To achieve optimum noise reduction, a fairly large air gap (about two inches) is placed between two windows of unequal thickness. This can be done by adding a secondary window to the existing one or by replacing the existing one with a double window assembly.
Primary Exterior - solid core exterior doors are installed to replace lightweight hollow core or panel doors, which are significant transmission path for noise.
Secondary Storm Door - if owner chooses to retain existing door, a secondary storm door may be used.
Sliding Glass Doors - sliding glass doors that achieve high noise reduction are slightly heavier and may require some extra force to open, but they are a better alternative to the cumbersome addition of a second door.

Most roof structures can be improved to meet sound insulation goals by simply adding thermal insulation materials to the attic space. These materials absorb sound as it echoes around the attic, and improve the overall noise reduction from outside to beneath the ceiling of a room.
The benefits of sound insulation can only be achieved with windows and doors closed. This means that ventilation (air) should be provided through a system, which does not allow noise penetration. Various types of ventilation systems have been shown to provide this capability.
Other seemingly simple noise penetration areas of a dwelling can become extremely significant and noticeable when windows and doors have been insulated.
