In the present study, an analytical model has been proposed to specify the relationship between the acoustic parameters such as acoustic impedance of honeycomb and the honeycomb geometry. In this regards, three materials (Polycarbonate, Polypropylene, and Polyurethane), seven angles (45°, 30°, 15°, 0°, −15°, −30°, −45°), and three cell arrangement (1 × 1, 2 × 2, and 3 × 3) were considered to find out the effect of these parameters on the sound absorption coefficient. Sound absorption in the frequency range of 1–500 Hz for angles of 45°, 30°, 15°, 0°, −15°, −30°, −45° was demonstrated using MATLAB software. A comparison of the results showed that the greater the angle’s absolute value, the more the sound absorption coefficient. By comparing all three materials’ absorption coefficient values, it was concluded that the 1 × 1 arrangement had greater absorption than the 2 × 2 and 3 × 3 arrangements. Also, the number of resonance peaks of polyurethane material for all angles was greater than the others in the same frequency range. Then, the panel with the honeycomb core of Polyurethane and 1 × 1 arrangement was recommended for cells with an internal angle of −45° in the present research case study for having more sound absorption.","PeriodicalId":51841,"journal":{"name":"BUILDING ACOUSTICS","volume":"29 1","pages":"263 - 294"},"PeriodicalIF":1.7,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46079757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research and development of green walls are steadily progressing in multiple fields, including but not limited to the environmental, social, and economic areas. Compared to other themes, the number of acoustic studies of green walls is relatively low and lacks relevant review papers. The purpose of this paper is to give a systematic review of the application of green walls in the acoustic field and clarify the key factors that influence the acoustic performance of green walls and the main obstacles that obstruct the broader application of green walls. A total number of 34 papers published in the past 10 years are reviewed. This study identifies that the acoustic applications of green walls are mainly in four aspects, namely laboratory applications, outdoor applications, indoor applications, and audio-visual applications. Vegetation morphology and properties of substrates are the two crucial factors determining green facades and living walls’ acoustic properties, respectively. High installation, operation, and maintenance costs and plant-induced problems are recognized as the main obstructions. A few possible topics are recommended for future study as well.","PeriodicalId":51841,"journal":{"name":"BUILDING ACOUSTICS","volume":"29 1","pages":"295 - 313"},"PeriodicalIF":1.7,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49021155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of the methodology to floating floor systems is of great interest, since, compared to the conventional method (ISO 10140-3), it is less costly and would require smaller specimens. However, previous studies have revealed an influence of the modal behavior of the slab on the sound insulation in the frequency range, causing the ΔL curves to show abrupt oscillations (peaks and valleys), thus deviating from the reliable insulation values and decreasing their accuracy. This study proposes the use of ISO 16251-1 for the evaluation of floating floor systems investigating the main factors that influence the accuracy of laboratory tests and the performance of the devices, namely dynamic stiffness of the resilient layer, total loss factor, and dimensions in the floating slab area. The results of ΔL and ΔLw obtained according to ISO 16251-1 were compared to those of two analytical models and the conventional method for 17 samples of floating mortar screeds of 0.96 and 0.36 m2 areas, 10.8–340.6 MN m−3 dynamic stiffness, and 0.04–0.39 total loss factor. The 0.96 m2 samples showed less abrupt oscillations in the ΔL curves than those of 0.36 m2, and the oscillations recorded for resilient layers of above 68.4 MN m−3 stiffness were minimal when the larger floating slab was used.","PeriodicalId":51841,"journal":{"name":"BUILDING ACOUSTICS","volume":"29 1","pages":"239 - 262"},"PeriodicalIF":1.7,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46233950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, understanding these interactions is critical to enhancing human well-being. Aural attributes play a significant role in shaping the perception of space in addition to visual attributes. It is well known that sounds evoke an emotional response, but less is known about how the acoustic characteristics of environments reinforce such an emotional impact. By adopting virtual reality as a platform for recreating 3D sounds and 360° visuals of built environments of worship spaces as case studies, this study aims to investigate the influence of the acoustic environment considering audiovisual congruency on enhancing the human experience through self-report and physiological response analysis. It also examines the role of cultural background in terms of familiarity with the acoustic environment. The convergent mixed-methods approach, merging both quantitative and qualitative analysis, provides a deep understanding of the role of the acoustic environment in enhancing the auditory experience. The results show that the acoustic environment and audiovisual congruency amplify the intensity of the emotional impact, and the amplification of the impact can vary depending on the acoustic environment of the building. They also reveal that familiarity with sound and acoustic characteristics can increase this impact.","PeriodicalId":51841,"journal":{"name":"BUILDING ACOUSTICS","volume":"29 1","pages":"85 - 106"},"PeriodicalIF":1.7,"publicationDate":"2022-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47434383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings of a numerical study are presented. Software was used to assess effective noise attenuation solutions for naturally-ventilated classrooms exposed to traffic noise. A typical situation in urban schools in Gauteng, South Africa, is considered in which classrooms are ventilated by large open windows in accordance with national building regulations and norms and standards for school design. The aim of the study was to establish a heuristic framework for early design decisions regarding how far from the road a classroom building should be set, and the effective height and position of a solid noise barrier to ensure a suitable ambient noise level inside a classroom with open windows. Efficacy was measured with reference to an indoor ambient sound level of 40 dBA. The findings show that with the insertion of barriers, the required ambient level was achieved for a classroom at least 68 m from the road, if the barrier is at least 3.5 m high. However, it was found that a significant insertion loss (>6 dB) and an improved signal to noise ratio could be achieved for classrooms as close as 17 m from the road with a barrier of at least 2 m high. Though not broadly generalizable, the findings provide a heuristic guide applicable for designing new schools or selecting attenuation interventions in existing city schools that are similar to those used in the study.","PeriodicalId":51841,"journal":{"name":"BUILDING ACOUSTICS","volume":"29 1","pages":"63 - 84"},"PeriodicalIF":1.7,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48295597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only recently have the actual uses of auralization in the consulting community been explored, resulting in the identification of a variety of uses, including (1) to present to clients, (2) to test design ideas, (3) as a verification tool, (4) as a verification tool, (5) as a marketing tool, and (6) to improve internal company discussions. Taking advantage of methodologies from ergonomics research, the present study investigates effective uses through the observation of a collaboration project between an acoustic research team and an acoustic consultant, as a case study. Two spaces have been auralized in the context of the conception of a new skyscraper during the design phase of the project. The two spaces faced different problematics: an Atrium for which three different acoustic treatment options were suggested and experienced through multi-modal auralizations and audio-only auralizations of an Auditorium where an intrusive noise was to be acoustically treated. The ergonomic observation and analysis of this project revealed key impediments to the integration of auralization in common acoustic design practices.","PeriodicalId":51841,"journal":{"name":"BUILDING ACOUSTICS","volume":"29 1","pages":"179 - 199"},"PeriodicalIF":1.7,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"65424457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
