When a standard office is next to another office, the sensitivity to noise is typically Low or Medium and the potential for noise is typically Low or Medium. A Good to Better sound blocking level of STC 40-45 is required by the acoustics standards and guidelines. Executive offices and conference rooms have a High sensitivity to noise, so the sound blocking level increases to High (STC 50). Blocking is not relevant in open offices.
