Abstract

Apartment noise has become more in focus recently, and most European countries have strict normative limits, whilst some countries have even stricter voluntary limits. Elevator suppliers work to guidelines for minimizing sound emission from elevator shafts into the residential location, but as with other service equipment, with their moving, sliding and rotating electro-mechanical components, complete silence is not practical. The sound transmitted from elevators though the building tends to be structure borne rather than airborne, but elevator safety codes restrict the flexibility of connections between the elevator structure and the building structure. On the other hand there is a trend in the building industry to optimize building materials, and this brings a challenge to sound insulation. Therefore it makes sense to collaborate with
building designers to optimize the acoustic solution for residents. ISO standard EN 12354-5 was used as a basis to create a calculation tool to estimate the structure borne noise in a room behind an elevator shaft wall. Using measured data, transmission through the shaft wall is calculated using power balance methods.
Material properties of the shaft wall, acoustic room parameters and excitation force normal to the wall were used to estimate the resulting noise in the room. The calculations have been verified against several test cases and are used by our sales engineers to work with customers to optimize the elevator in its building.
