Review of elevator noise and vibration criteria, sources and control for multifamily residential buildings

摘要

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