This study explored subjective responses towards various environmental quality parameters. In order to investigate the combined effects of sound, light, and heat on the overall comfort (evaluated by overall comfort vote, OCV) of pedestrians, two residential areas in Yubei District, Chongqing (a Cfa city in China) were selected for field measurements combining questionnaires. Three main conclusions were drawn. Firstly, the average outdoor neutral temperature (NT), LAeq, and LUX were 26.6 °C (indicated by physiologically equivalent temperature, PET), 56.5 dBA, 21.4103 lx, respectively. Secondly, since the effects of both physiology and psychology, thermal perceptions varied for acoustic and light environments. This could be explained by the different NTs in various sound pressure or light levels. Thirdly, environmental quality factors had significant effects on overall comfort. Significant positive correlation between heat stress (PET) and OCV was found (sig＜0.000); while the effects of sound pressure and light intensity were not always significant. Hence, thermal stress played a significant role in people’s overall comfort. Findings of this study were directive for future environment design for creating more physiologically comfortable spaces.

“…Ranpise et al (2021) worked on assessing the levels of noise at important arterial roads in the city of Surat and developed a noise forecasting model by utilising an artificial neural network. Shokouhian et al (2021) utilised Traffic Noise Model (TNM) to compute the noise caused by highway traffic and evaluate the effectiveness of noise reduction measures. A detailed comparison of different models has been presented in Table 5.…”

Most people are not aware that noise from road traffic is the principal cause of annoyance to exposed people. In relation to this, the review aims at providing an overview of research carried out on noise pollution monitoring, mapping, modelling, and health impacts in recent years in different countries. The electronic databases were searched to select the studies related to noise monitoring, mapping, modelling, and health impacts on humans. A total of 91 most relevant studies were reviewed in this article. A comparison of different instruments available for noise monitoring was done. Studies related to monitoring and mapping reveal that most of the locations have higher noise levels in the environment, breaching the noise limits. Only a few articles enumerated health impacts and zone-specific monitoring. Many researchers have conducted a questionnaire-based study related to health to identify the impact of noise. Noise models for many developing countries are not available, so their development and modification are still in progress. Proper zone-specific studies and noise maps will help the town planner with better land use planning. Continuous monitoring stations for noise in crowded cities shall be implemented to mitigate noise pollution. Based on the review, it is concluded that long-term research on noise pollution is very much needed worldwide.

“…The optimization of material design is characterized by varying filler content with the polyester matrix. This composite material is targeted as a noise barrier for high-noise transportation tracts close to residential areas, such as near railway traffic noise (Zheng et al, 2022;Abdulkareem et al, 2021) and highways (Shokouhian et al, 2021).…”

Transportation tracks of railways and highways are the highest noise pollution contribution to the inhabitant urban due to the sources near residential areas. Many researchers proved that the composite material could help reduce the noise by 30%. This study focuses on designing local nature fiber composite for developing a good sound absorption material by providing experimental methods. Three natural fibers of coconut, palm oil, and sugarcane are used to make a composite by varying filler content for sound absorption and transmission loss observation. The results found that sugar cane bagasse is suitable for average performance in varied filler content for both sound absorption and transmission loss. The overall results showed a successful improvement in both sound absorption coefficient and transmission loss with the addition of fiber content.
