Annoyance Based Vibro-Acoustic Comfort Evaluation of as Summation of Stimuli Annoyance in the Context of Human Exposure to Noise and Vibration in Buildings

Abstract

This paper presents the issues of assessing the comfort of people staying indoors who are exposed to vibrations and material noise caused by vibrations of partitions like floors and walls (ground-borne noise). Current criteria in the evaluation of vibrational and acoustic comfort cannot be assessed in the context of the simultaneous occurrence of stimuli such as noise and vibration. Railway transport, including passenger and cargo transport, is becoming increasingly prevalent, and new railway lines are being planned for environmental reasons. Sometimes, there are changes in stimuli produced by existing railway lines. For example, high-speed trains appear on an old railway track. Such a situation appeared on the Central Railway Line in Poland, which is still used by old trains, yet its operator plans to raise their speed limits. The analysis of the problem of the simultaneous occurrence of stimuli presented in this paper was based on measurements performed in a residential building located near the Central Railway Main Line in the city Zawiercie. Noise and vibration as the analyzed stimuli in both cases meet comfort requirements, yet when exposure to two stimuli was considered, comfort may be at risk.

Determination of Vibroacoustic Parameters of Polyurethane Mats for Residential Building Purposes

“…This leads to the conclusion that during the design process, an analysis must be conducted to determine the "sweet spot" where acoustical advantages will not overcome the vibration aspect. A method to address this problem can be found in [36].…”

Railway Line Occupancy Control Based on Distance Determination Sound Method

“…The pilot studies show the possibility of using an acoustic wave as an information carrier on an approaching train, e.g., warning time associated with lowering the gate. Thus, it can be considered as having potential applications, for example, as support for the railway safety system or monitoring system [36,37].…”

“…Of course it has to be underlined that railway traffic causes problems with noise and ground-borne vibrations, especially in areas where the ground is composed of clay [35]. When considering ground-borne noise and vibration from railway vehicles, exposure to human annoyance is often considered [36,37]. All these issues are extremely important, especially in the case of monitoring traffic noise in a large urban area [38].…”

Effects of railway noise and vibrations on dissatisfaction of residents: case study of Iran

“…In general, a good number of researches have been done that examine the issue of noise pollution and vibrations caused by railways. Some of this research has only focused on noise pollution caused by railways (Grubliauskas et al, 2014 ; Zhang & Ma, 2021 ), and some other only deals with rail vibrations (Connolly et al, 2016 ; Peris et al, 2012 , 2014 ; Sharp et al, 2014 ) and there is a limited number of papers which investigated as a novel approach, the efficiency of combining railway vibration and noise barriers (Maigrot et al, 2020 ; Nering et al, 2020 ; Peplow et al, 2021 ).…”
