Where required to provide
42、adequate room to room sound attenuation, entire ceiling assembly, including air terminals and light fixtures, should have appropriate Ceiling Attenuation Class (CAC). Any penetration of ceiling assembly will destroy integrity of ceiling in this regard. Verify that other specification sections and dr
43、awings include appropriate data to ensure that these requirements are met for air terminals and light fixtures. For standard applications, specify CAC range of 35 - 39. A ceiling CAC range of 40-44 is recommended for all spaces where speech privacy is required and that are surrounded or sub-divided
44、by partitions which do not extend to underside of floor or roof deck above. For classified conference rooms, executive offices, teleconferencing rooms and other occupancies requiring the highest degree of speech privacy, sound attenuation requirements will have to be achieved by other means, most likely by high sound transmission class (STC) partition extending to the underside of floor or roof deck above.*Provide a ceiling system with an attenuation class (CAC) of _ for _ and _ for _ when determined in accor
