Determining target STCs is one of the first acoustical analyses an architect or consultant should perform when designing a new structure. Since the cost of construction often increases with the level of STC desired, it’s important to determine an acceptable STC without overdefining the requirements. While Commercial Acoustics spends much effort helping architects and developers get to their STC targets, we also pride ourselves in helping them find the ideal target for their development which can be reached in a cost-effective manner.

Commercial Acoustics Target STCs

In addition to common residential target STCs, which are partially or fully defined in the building code, the following commercial STCs are commonly seen:

Classrooms: 40-45

Teleconference Rooms: 45-50

Office Space: 35-45

Sensitive Office Space (Physician Office, Law Office): 45-55
