In addition, each assembly references a ROCKWOOL test number, as well as the ROCKWOOL Building partitions, façades (exterior walls), and façade elements (windows and doors) may require a rating for sound transmission. Because of the larger range in expected sound, OITC values are determined for lower frequencies as well, in the range of 80 to 4000 hertz. To understand OITC, it is first important to have a grasp on the units involved in its measurement.
