Abstract: Building Acoustics, Ahead of Print.
After the World War II, Albania was governed by a dictatorship that lasted for about 50 years. The cultural life restarted to be one of the main centers of the society community. Many buildings styles reflected the influence of governors as leaders of countries, in combination with the spread of armed concrete used as the main material for new constructions, given its flexibility compared to brickwork that was not yet developed as it is nowadays. In Albania, many cultural centers were constructed for the local community where citizens can have access to libraries, coffee shops, and auditoria. These latest ones represent the places where live shows are performed, along with international conferences. This paper deals with the assessment of the acoustic response gathered within three auditoria as part of cultural centers in Albania. The acoustic measurements were carried out in accordance with ISO 3382-1. The acoustic response recorded inside the three case studies indicate a good listening condition for both speech and music performance. This outcome has been found in all three auditoria, despite the room volume between each other is different.

Abstract: Building Acoustics, Ahead of Print.
The acoustics of Palacio de los Deportes in Mexico City, a former sport venue for the XIX Olympic Games in 1968, currently in use mainly for massive modern music concerts, was studied by performing measurements in situ, in-lab speech intelligibility tests from measured impulse responses, and by computer ray-tracing simulations. Long reverberation times and late strong echoes were found as the main acoustic disturbances severely affecting speech intelligibility, and acoustic quality indices D50, C50, C80. A simulated solution is proposed including curved diffusers and absorbing treatment that could bring reverberation times and intensity of echoes toward values more suitable for pop and rock events with an expected improved acoustic quality. The acoustics of Palacio de los Deportes is put in context with those of the AO Arena in Manchester and the O2 Arena in London, two similar comparable venues that are well regarded on account of their popularity and acoustic quality.

Abstract: Building Acoustics, Ahead of Print.
Neighbour noise affects health, emotions, behaviours, privacy and social relations. This paper aims to present residents’ perspective on neighbour noise and initiate a discussion on consumer rights and protection based on the results of a social media analysis. In 2021, two newspaper articles about acoustic labelling and neighbour noise were published, receiving over 700 comments in social media. A thematic analysis revealed the experiences in multi-storey housing, and attitudes toward noise sources, responsibilities and solutions. Considering the heterogeneity of apartment users and needs, the economic burden of real estate transactions, and the difficulty of redressing issues, we argue that performance disclosure, for example, through acoustic labelling, is an urgent necessity for providing informed choices to house-buyers and tenants. The results further indicate the need to address the vulnerabilities of certain groups, not only from noise exposure but also from being overheard.

Abstract: Building Acoustics, Ahead of Print.
This manuscript denotes the results of the Interlaboratory Comparisons (ILC) conducted to test the proficiency of accredited laboratories (23) according to in situ measurement methods described in ISO 16283-1:2014/A1:2017, ISO 16283-2:2020 with ISO 717-1:2020 and ISO 717-2:2020. The comparison of all measured parameters and single number building acoustic parameters is presented with attained measurement uncertainties. The overall influence of all uncertainty components on the final results is taken account for sound reduction index and normalized impact sound pressure levels. The measurement uncertainties are obtained by performing one independent measurement from each laboratory and they are determined at the end for all results in reproducibility and repeatability conditions. The obtained values for measurement uncertainties are compared with values given in standard ISO 12999-1:2020 and with previous ILC2015-s results for airborne and impact sound insulation parameters when five independent measurements have been done. The experimental measurement uncertainties for single number results are lower (in average 0.3 dB for u(R′w) and in average 1 dB for (L′n,w)) than values given in standard ISO 12999-1:2020. The experimental measurement uncertainties calculated from reproducibility in one-third octave bands are not smoothed compared to the situation when five independent measurements are done.

Abstract: Building Acoustics, Ahead of Print.
This study investigates the acoustic performance of various porous materials at elevated temperatures, employing Constrained Gaussian Process Regression (CGPR) to model the relationship between specific airflow resistance and the absolute temperature. Experimental data on six fibrous material samples at 600°C are used to develop and compare CGPR models against conventional Power Law Regression (PLR) methods. The developed CGPR incorporates constraints such as boundedness, monotonicity and convexity/concavity derived from the evident relationships and prior knowledge of the specific airflow resistance versus temperature variations. The results of this study prove the outperformance of the developed CGPR over PLR methods in terms of data efficiency, predictive accuracy, uncertainty quantification, overfitting recovery and extrapolation capability. This comparative analysis outlines a significant improvement in the predictive accuracy of CGPR, achieving improved coefficient of determination values compared to PLR. CGPR also furnishes a direct strategy to quantify the uncertainty of predictions which is vital for applications at elevated temperatures. Additionally, CGPR offers valuable insights into sound absorption behaviour, highlighting its applicability in thermal acoustics and materials engineering. Prospective research avenues stem from this research as the developed CGPR technique has the potential to replace various modelling techniques in materials science and acoustic engineering applications.

Abstract: Building Acoustics, Ahead of Print.
Finding a metric to evaluate the sound quality of a given product is a challenging task. It depends on multiple criteria and dimensions. This study proposes a soundscape approach to assess the pleasantness of the acoustic environment in an open-air heritage site, the Corral del Carbón in Granada as a complementary tool for selecting concert venues in addition to environmental and room acoustics criteria. Acoustic measurements and surveys were conducted at two locations: the patio of the building and the adjacent street. The methodology involved soundwalks with participants who provided subjective assessments, complemented by objective acoustic indicators and psychoacoustic parameters. The results reveal a significantly more pleasant acoustic environment inside the patio than the street. This kind of comparisons between sites provide information on which is a more suitable setting for concerts. Soundscape approach offers a practical tool for selecting concert venues in heritage contexts by emphasizing the importance of the perceptual experience of the audience, thereby enhancing the decision-making process for concert programmers and acousticians.

Abstract: Building Acoustics, Ahead of Print.
The acoustic comfort and environmental concerns in the building sector are two interconnected and crucial aspects for the sustainable development of the construction industry. This study investigates the acoustic absorption properties of plasterboards reinforced with woven fabric made from Moroccan sisal fiber. Three different weave designs, Basket 2-2, 2/2 Twill, and 4-Harness Satin, were produced using a conventional weaving process. Plasterboards were manually fabricated by varying the number of fabric layers (one, two, or three) and employing a water/plaster ratio of 0.7. The acoustic performance of the plasterboards was evaluated using an impedance tube according to ISO 10534-2. The results demonstrated that the plasterboards reinforced with the Basket 2-2 weave achieved the highest sound absorption coefficient, reaching 0.39 at 1700 Hz with three layers, significantly higher than pure plasterboards, which exhibited a maximum coefficient of 0.05. The study also employed support vector regression (SVR) models to predict the sound absorption coefficient, with the linear SVM model achieving the best predictive accuracy (R² = 0.88, RMSE = 0.024). These findings underscore the potential of Moroccan sisal fiber as an eco-friendly reinforcement for improving the acoustic absorption of plasterboards.

Abstract: Building Acoustics, Ahead of Print.
In this work, the influence of the modulus of elasticity, the loss factor and the density of reinforced concrete on the vibration transmission index ([math]) of a reduced concrete bench was evaluated. An experimental modal analysis based on the Operating Deflection Shape (ODS) methodology is carried out on a reinforced concrete slab (1.20 × 0.80 × 0.20 m) supported on four concrete pillars, applying four sources of distinct impacts: mallets of 1 and 4 kg, impact machine and one person jumping. The experimental results served to validate the finite element bench model (FEM) considering both the first four modes of slab vibration and the adjustment of the elasticity and shear modulus, the loss factor and the density of the concrete using the NSGA genetic algorithm-II. The [math] index between the slab and the columns was determined experimentally, numerically and analytically, according to the Gerretsen model. The FEM model showed a percentage difference in the frequencies of the vibration modes less than 10% concerning the tests for the [math] index. The influence of density and the modulus of elasticity mainly in the direction perpendicular to the plane of the structure modify the values of the frequencies of the vibration modes by up to 10% without interfering in the modal forms of the structure. In addition, the internal loss factor alters the amplitude of the [math] results by an average of 10 dB. Finally, it is shown that the stiffness varies according to the orthotropy of the material. It was possible to conclude that the computational model showed good convergence in results ([math]%) when compared with the [math] experiments, with the same varying along the frequency, different from what is proposed in the analytical and normative models. This fact proves the hypothesis raised that structural couplings in practice generate significant interference in the results, as happens in residential buildings, with the test bench being an important experiment for initial predictions with little interference from energy transmission to the environment.

Abstract: Building Acoustics, Ahead of Print.
This study examines 22 peer-reviewed papers to offer insights into the current utilization of psycho-acoustic sound quality metrics in research focused on indoor soundscapes. The selection of papers followed the PRISMA method for systematic review, followed by descriptive and bibliometric analyses. The review focuses on (i) identifying what psycho-acoustic indicators can be utilized to obtain an objective soundscape assessment, and (ii) determining if soundscape descriptors vary with the desired activities within the indoor space. The findings provide an overview of how psycho-acoustic sound quality metrics are used to predict perceived annoyance in indoor environments. The discussion delves into response variables related to occupants’ sound perception across various indoor settings. It highlights the lack of sufficient research on prediction models based on psycho-acoustic sound quality metrics within indoor soundscapes. Further research is required to develop tools enabling the optimal design of indoor soundscapes, which can vary according to the intended use of the room.

Abstract: Building Acoustics, Ahead of Print.
Preschool is an important time for children to grow in their experiences, abilities, and knowledge before entering formal school. Therefore, it is vital that the classroom acoustic environment supports children’s listening, learning, and wellbeing. The aim of this scoping review was to determine what is known from the literature about the effect of classroom acoustics and noise on preschool children’s listening, learning, and wellbeing, and what the knowledge gaps are. The scoping review followed the PRISMA-ScR guidelines. Seven papers met the criteria to be included in the review. The findings suggest that poor classroom acoustic conditions and particularly high noise levels, can have a negative effect on preschool school children’s listening and wellbeing, but may not affect word learning at the SNRs investigated. Nevertheless, it would be beneficial to install acoustic solutions and manage noise in preschool classrooms to enhance children’s listening, learning, and wellbeing. Future research avenues are discussed.
