“…To further study the frequency-domain features of the monitoring data, power spectrum density (PSD) analysis and 1/3-octave frequency analysis, are employed. These allow for the identification of specific frequency components associated with noise or vibration sources [28]. By transforming the vibration and noise signals from time domain to frequency domain, a visual representation of the frequency distribution of the signals can be obtained.…”

“…Previous studies related to the in-situ measurement of vibration and noise were mainly the 'one-off tests', and many of the tests were basically used to validate and improve the prediction model of dynamic behavior of different structures [4,8,[25][26][27][28]. Zhang et al [12] present a field measurement for the vibration caused by the passage of both intercity trains and subway trains.…”

The concrete floating slab, as a widely-used measure to reduce the subway-induced vibration and noise, can deteriorate with the accumulation of trainload. To monitor the dynamic performance of the floating slab during operation, this study develops a lightweight sensing unit based on MEMS. This sensing unit, which can be easily mounted on the concrete slab, enables synchronous monitoring of vibration and noise at different sampling frequencies with a very low power consumption. With the advantage of easy installation, the sensing units are mounted on various concrete slabs and tunnel walls to collect massive vibration and noise data. With the monitoring data, the dynamic performance and vibration reduction capability of the floating slab can be assessed. A case study is conducted on two floating slab sections: one section has a floating slab with a potential defect on its shear hinge and the other has a normal floating slab. The monitoring results show that: 1) the train condition has a significant effect on the amplitude of the track-side vibration; 2) the train-induced noise data last longer than vibration data during the passage of trains; 3) for the floating slab with shear hinge defect, the vibration levels at edge points are much higher than that in the middle. Through the monitoring test, the performance of the MEMS-based sensing unit and its adaptability in subway circumstances are verified.

Ecotherapy healing forest (EHF) is a new approach that utilizes forest resources for health and increasing ecosystem value. EHF is an alternative that functions to provide physical and mental health interventions by utilizing the environment and forest ecosystem. Ecotherapy healing forest can also help ensure that environmental conditions can always be maintained, so that people's health and welfare can improve, in line with the Sustainable Development Goals (SDGs). This research was conducted in the area of Mount Kelam National Tourism Park, Sintang Regency, with data collection time in August 2022 -January 2023. Location selection is determined purposively by considering accessibility, travel time, and location value. The method used uses a site identification approach carried out on the routes available at NTP. The suitability of the Mount Kelam NTP location as a new EHT location was carried out by taking measurements at 6 location points covering an area approximately 8 ha, including measurements of vegetation, microclimate, noise level, wind speed and negative ion content. Based on the results of the analysis of site identification, community perceptions and preferences, site carrying capacity, and thermal comfort, the Mount Kelam Sintang Natural Tourism Park conservation area is very representative of being a site of ecotherapy healing forest which is beneficial for health. The final results of this research are described in the form of design recommendations for the site of ecotherapy healing forest at the six observation points.

“…It is widely recognized that the indicators used in environmental vibration evaluation vary across different countries and regions, leading to a lack of harmonized assessment methods in this field [12][13][14], as show in table 1. Due to the complexity of the phenomena and the large number of associated parameters, the application of the relevant standards to each other is difficult and sometimes confusing [15,16]. For measurement index, since train-induced building vibration displacements are small, this makes it difficult to measure displacements.…”

The main negative impact of the residential buildings located on the cover structure of a Transit Oriented Development (TOD) metro depot is that residents would suffer from the train-induced annoying vibrations. Arguments accordingly arose on the possibility of evaluating indicators controversy for this application that acceleration data was more captured in the past while velocity would be more related to structure born noise. Therefore, this paper provided a relative comparison based on a measurement campaign that both velocity and acceleration sensors were installed together at the same time. The collected vibration accelerations and velocities are analyzed and discussed using the methods of transmission loss, coherence, and time and frequency domain analysis. The results indicated that even there was no differ-ence for identifying the resonance frequency of structure, but the transit mobility and human annoyance evaluation were obviously different by using velocity or accelera-tion. Attempts to establish a relationship between the two indicators using the calcu-lus method failed because they showed the largest error at the peak frequency at the same vibration level, which would have affected the evaluation results and the judgment on the choice of mitigation measures.
