OITC, on the other hand, covers a broader frequency range (80 to 4000 Hz), including lower frequencies often associated with external noise. Notably, road noise is a lower frequency sound, so depending on the proximity to busy streets and interstate highways, it is important to consider the OITC rating and look for higher numbers. Jan 11, 2025 · If meeting an architectural specification that requires, for example, an STC 35 instead of the STC 34 you might meet with dissimilar glass, laminated glass may be necessary. One thing that I’m not clear on: how would I know how high of an OITC rating I need? I’m guessing that I would use a sound/decibel meter to measure the undesired noise, estimate a desirable/tolerable noise level (in decibels), and calculate the difference (bad noise decibels minus good noise decibels, if you will). An OITC rating is best assigned to specimens tested in the laboratory. I do need to point out to you that there are numerous combinations of glass (thickness of components and overall thickness of an insulating glass unit).
