Abstract
The study investigates the sound levels registered inside the apartments in residential buildings resulting from the operation of the passenger lift installations. Modern multi-family residential buildings are typically equipped with machine room-less (MRL) passenger lift installations where the drive units are mounted directly on the shaft walls. Noise and vibration of the passenger lift operation has now become a major concern. Errors in engineering designs can lead to elevated noise levels in residences, particularly those adjacent to the lift equipment. Subsequently, this may result in exceeding the permissible values of noise level, also vibrations in the apartments. Exceeding the permissible values of vibration and noise level on the one hand is a problem for users of residential premises, and on the other hand, it has an economic dimension, because the improvement of irregularities is often very expensive and financially burdens the developer. This paper summarizes the results of studies highlighting the problem of elevated sound levels in residential areas adjacent to the shaft. The measurements of vibrations and noise in the apartment, as well as in the elevator shaft, showed that the vibroacoustic (V-A) signal is transmitted from the device to the flat. Spectral analysis and signal variability in the time domain were used. As part of corrective actions, mitigation measures and vibration isolation strategies have been proposed, however, not all proposals were feasible. Measurement results obtained prior to and following the vibroacoustic adaptation are compared in the context of noise and vibration control.
