Elevators in residential buildings present the potential for intrusive noise and vibration to the dwelling units. The adverse noise and vibration can result from the elevator equipment located in the machine rooms or the shafts. The impacts can be significant issues related to the sound quality, sleeping conditions, and enjoyment within residences. There are often challenges to identifying the transmission path (airborne vs. structureborne) and how the transmission paths can be mitigated to reduce the noise and vibration. Issues relating to the reliability and safety of the elevator operation can introduce difficulties and conflicts with implementing mitigation. This presentation will discuss various criteria to consider for quantitatively assessing the effects of noise and vibration from elevators. In addition, two different case studies describe the conditions and mitigation for a mid-rise traction elevator machine room and from a hydraulic elevator machine room.
