Abstract It is vital that people concentrate and focus on the types of sports and amenities in the context of sports facilities to provide acoustic comfort for players and fans. Thus, influences the ...positive or negative psychological and emotional impact experience during the sports matches. Esports events are mostly organized in enclosed spaces facilities such as indoor arenas or stadiums, which are spaces where speech intelligibility and noise level determine, to a large extent, the listening comfort or even the safety of the occupants. More noise may distract players throughout the match and during the match, interfering with their performance and communication with coaches if there is no proper sound blocking or insulation. This research will look at critical literature studies of the defining elements and criteria for this occurrence to develop a conceptual framework for how players, coaches, and spectators experienced acoustic comfort in various types of Esports venue. The primary goal of this research is to clarify the differences in Esports venue design and the determining factors that influence human acoustic comfort. As a result, the goal of this study is to create a framework based on the elements that determine acoustic comfort classification in Esports venues. Designers and architects able to utilize this framework as a guide to assist them prepare estimates of acoustic conditions and corrective activities in Esports venue which tailored suited to players, as well as the effects on staffs and spectators, thus create a highly immersive experience.
This study explores the physiological and psychological recovery effects of outdoor soundscapes on the elderly in urban nursing homes. In this study, virtual reality technology was used to reproduce ...the outdoor audio-visual environment of a nursing home for 29 older adults in a laboratory environment. The experiment used a within-group design to measure the participants' physical and psychological responses. The physiological indicators included skin conductance level (SCL), heart rate (HR), heart rate variability (HRV), respiratory rate (RF), and blink frequency (BF), and the psychological indicators included emotional level and attention. This study confirmed that the outdoor soundscape in nursing homes has inductive and restorative physiological and psychological effects on elderly people by comparing the data from the audio-visual experiment and the pure video experiment. Additionally, it was found that an environment that is too quiet has the potential to impair the mental state of elderly people. We also found that in addition to SCL and HR, many physiological indicators showed noticeable changes after 1 min. Time trends in changes in SCL and positive mood indicators were statistically significant. The data and findings of this study can be widely used in future in-depth research on aged care settings.

Abstract The microperforated panel (MPP) is a unique panel that has evolved from the traditional perforated panel. Previously, the perforated panel was mainly used as a protective cover for porous ...materials. The MPP absorbs sound through the viscous effect around its perforated holes. However, traditional MPPs are typically made from metallic materials that are not environmentally friendly. In contrast, polylactic acid (PLA) is a biopolymer extracted from natural resources such as corn and sugarcane. When buried in soil, PLA degrades naturally with the assistance of soil bacteria and fungi, making it an eco-friendly choice. In this study, 3D printing method was utilized to produce MPP using PLA as the material. The sound absorption performance of PLA MPP was compared to steel MPP, which served as the benchmark. Interestingly, the sound absorption performance of PLA MPP was found to be comparable to that of steel MPP. This highlights PLA as a viable material for MPP production, aligning with the global goal of environmental preservation and Sustainable Development Goal (SDG) 12, which emphasizes responsible consumption and production.
Purpose
This paper aims to investigate the diners’ preference and perception on six acoustic classifications in eatery places during their casual dining. These classifications’ relationship with ...diners’ experience and significant impacts on diners’ preferences and perceptions during casual dining will be analyzed.
Design/methodology/approach
The data was collected quantitatively with randomly distributed self-administrated questionnaires during the restaurants' operating hours; 449 respondents who dined in at two casual dining restaurants in Melaka city area participated.
Findings
Analysis of Variance (ANOVA) tests revealed that the majority of the diners were not adversely affected by the noise level, and they did not have difficulties with their conversations. The results also indicated that the respondents felt that the noise did not stop them from returning to the restaurants. This study's findings may lay the groundwork for future studies to provide the acoustic comfort classification in eatery places, which can also be integrated and synthesized to be used as a reference for acoustic design and practice.
Research limitations/implications
The number of participants used simple random sampling method. Therefore, the sample cannot be typical for the target population, and there is a limited possibility of generalizing the present findings. The data collection was only gathered from two eatery places with similar typologies at the similar demographic background of customers because it was collected at Melaka city. Thus, the impacts of customers may differ at other typologies and locate in different regions, and the physical environment and the quality offered are also different in other places. The measured determinant factors only focus on the diners’ characteristics; thus, future research should be done to investigate other determinant factors impacting the preference and perceived acoustical comfort in eatery places.
Practical implications
The findings in this study would provide a basis reference to assess and evaluate the acoustic classification in eatery places that suits the customers’ perceived satisfaction.
Social implications
This study identified that demographic characteristic, gender and age are not the prominent determinant factors influencing the diners’ preference and perceived acoustical comfort in eatery places. Moreover, the days and dining hours were also found to be the determinants that will influence the preferences.
Originality/value
This paper has developed determining factors on acoustics classification that can be applied upon designing eatery places as well as a fundamental approach in developing rating for acoustics comfort index as reference for the diners to choose where to dine based on their preference and activities.
Abstract
The value of heritage sites is often distinguished through their architectural and physical features. However, the characteristic of a place is forged through the combination of multiple ...sensory elements. Acoustic is an essential element in the study of heritage spaces related to music, performance, congregations, etc. However, in the study of heritage sites, the acoustic elements are often overlooked even though they are an important element that adds spirit to the place. How people perceive their environment aurally is just as important as how they perceive it visually. This paper discusses the application of soundscape assessment methods recommended in ISO/TS 12913-2:2018. The technical specification presented comprehensive guidelines and alternatives on how a soundscape assessment should be conducted. The field study method and all its data collection protocols are reviewed and explored for implementation in the study of heritage streets in Melaka World Heritage Site. Characterising the soundscape profile of Melaka heritage streets will assist in understanding another facet of user experience and the acoustic ecology of the site.
Rainwater is an alternative water resource to fulfill sustainable management of freshwater particularly in the regions receive abundant annual amounts of precipitation such as tropical Malaysia. To ...collect and store rainwater, rainwater harvesting system has been practiced since ancient from horizontal surfaces mostly rooftop of buildings in urban areas. Nowadays, this method in modern urban areas with tall buildings is considered inadequate and uneconomical because the ratio of facade surface areas is much higher than the ratio of roof surface areas. On the other hand, all rain has a horizontal velocity due to wind acting upon rain droplets which is called wind-driven rain (WDR). Growing tall buildings and the presence of WDR phenomenon make building façade surfaces the available promising surfaces to harvest substantial rainwater vertically and more efficiently. This article presents a one-year field measurement results that aims at quantifying the WDR loads impinged on the vertical facade areas of a pilot building located at the main campus of the University Malaya in Kuala Lumpur, Malaysia. Detailed descriptions of the gauge design, building, the measurements of on-site WDR, rainfall duration time, and weather data are presented. Records show that monsoon winds characteristics have significant influence on the WDR loads on the building facades compare to horizontal rainfall intensity. Finally, the collected in-situ data are exploited to validate data and determine WDR coefficient (γ) to estimate the amount of WDR on a building façade via an empirical WDR relationship. Results show the feasibility of each square meter of vertical façade area to supply 12% of non-potable or 4.9% of potable water-usage per capita per day.
All the time, caféis an essential partof our daily life -a node where people socialize, work, or even where they got their inspiration of idea. Lately, there been booming of adaptive reuse of ...heritage buildings to become caféalong the Jonker Street Malacca; each caféis various in size and theme. All these projects mainly to restore historical visual traits and focus on restoration through function change. Somehow, designers and planners always neglect the role of sound, which is very crucial element of our environment and daily lives whenmaking place making. Thus, this research is aimed to investigate and evaluate the level of the acoustical performance of adaptive reuse buildings at Jonker Street Malacca. Analytical method on a computational modelling of cafe will be used for this research which involved acoustical evaluation (noise level, reverberation time, Speech Transmission Index) simulation. Few cafe types were modeled in a room acoustic simulation application with a manipulated variable of volume, sizes and ceiling height. Basic sound field properties of typical cafe types are highlighted based on the finding of the study. The generated index from variables hopefully could be used to design and evaluate caféspecific acoustic environments in the future.
One of the important dining interests for focusing on smelling and tasting during dining in eatery places is having concentration or attention perceived of what we eat or drink. The dining ...satisfaction influenced positive behavior of return intent and recommending the eatery places to others. Higher noise level may distract the concentration for having a fine dining experience and could interrupt the ability of smelling and tasting senses. Settings in the noisy atmosphere of eatery places such as located near to a busy road, open kitchen, table layout and inappropriate decoration as well as the patrons' conversation behavior may affect speech intelligibility. Ultimately, the long period exposure towards high decibel sound and noise affecting not only the health and wellbeing but also the social interactions and communications. It is also having a direct significant impact to human preferences on acoustic comfort during their dining. However, there is no specific classification or rating system established in Malaysia to assist the information on acoustic environment obtained in the eatery place. The aim of this paper is to identify the framework of eatery places classification in Malaysia within the context of the acoustic comfort and its performance. The main concern is to elucidate clearly different categorization of eatery places which might have significant on human psychoacoustics. Based on ongoing research, this paper will discuss on the critical literature reviews to develop a conceptual framework in classifying eatery places typologies and diners' acoustical preferences.
