(A) Noise Problems

 

Structure-borne Noise

• Vibration from the vibration impact from the rolling or sliding between the lift guide shoes and guide rails may be transmitted through lift shaft wall which is part of the building structure. The vibration transmitted may activate the building structure to generate noise which causes noise disturbance to residents nearby (see Figure 36).

(B) Practical Remedies

 

Structure-borne Noise

• Provide vibration isolation pads for the guide rail (see Figure 37 and Figure 38). This involves operational safety of the lift, lift supplier should be consulted.
