摘要:
An elevator cab ceiling includes an upper ceiling panel and a lower ceiling panel that are vertically spaced apart from each other with an intermediate ceiling cavity between them. An inlet duct is associated with the upper ceiling panel and an outlet duct is associated with the lower ceiling panel. The inlet and outlet ducts are horizontally spaced apart from each other and are fluidly connected to each other through the intermediate ceiling cavity to form a ventilation path. This separation of inlet and outlet ducts by an intermediate ceiling cavity reduces airborne noise transmissions that enter an elevator cab through the ventilation path. In one example, at least one baffle is installed within the intermediate ceiling cavity between the inlet and outlet ducts to interrupt a flow between the inlet and outlet to further reduce any transmitted noise.
