Barriers can successively be the glass matrix (e.g. in vitrified waste), the package, engineered barriers for filling and anchoring, designed to protect the packages and prevent or slow down the flow of radionuclides to the geosphere in the event of deterioration, and finally the actual geological disposal environment in which the waste is placed

Sound attenuation provided by barriers is principally related to the sound transmission loss through the barrier material.
