OH3 Noise Protection



Intent 1:

To limit the probability that the improper method will be used to determine the flanking sound reduction index for the flanking paths at each edge of the separating assemblies, which could lead to miscalculation of the apparent sound transmission class rating (ASTC) by the simplified method, which could lead to occupants in one part of a building being exposed to excessive levels of airborne noise from other parts of a building, which could lead to negative effects on the psychological well-being of persons.
