Environmental factors in workspaces affect employee productivity and satisfaction, particularly in call centres. One of the most challenging issues in contemporary offices is overcoming the problems of concentration on work, despite adverse effects such as insufficient lighting, inappropriate acoustics, or inadequate ventilation. The challenges increase in open-plan solutions. This paper presents a case study from Turkey that elaborates on strategies to improve environmental performance in call centres. It is inspired by a questionnaire conducted among employees of a call centre, identifying existing design lacks. Based on the results, acoustic quality calculations of the physical workspace follow, and initial computing outcomes reveal that the conditions do not meet the standards for call centres. The authors propose strategies to improve acoustic performance in the workspace and apply them to a virtual model. Results reveal that the proposed solutions allow for meeting the standards. Based on the findings, the authors suggest several other strategies for improving the physical environmental quality of the place, thus forming a guideline for the architectural design of call centres. The study derives information from a specific case and context to propose universally applicable solutions. It fills a gap in the literature as it exemplifies the characteristics of call centres in Turkey, which have not been studied before.

Implementation of the new standard PN-B-02151-4 - Building Acoustics - Protection against Noise in Buildings, Part 4: Requirements for Reverberation Conditions and Indoor Speech Intelligibility and Testing Guidelines imposes on architects an obligation to design interiors in compliance with acoustic requirements. The above regulations give rise to the need to educate future architects so that the standard can be practically employed in their professional career. The aim of the article is to describe a teaching method tailored for students of architectural design compliant with the standard requirements without using specialized software programmes. The paper presents two types of design tasks that form a basis for teaching students within the framework of design practice in building physics - acoustics. The article shows how to teach students to facilitate full acquisition of the rules governing interior design compliant with reverberation parameters suitable for the assumed function, and to enable thorough comprehension of interior design.

The issue of sonic heritage in sacred historic buildings is gaining popularity and becoming a frequent subject of discussions. The Baroque St Joseph Church of Carmelite Fathers, a minor basilica, is, architecturally and culturally, an exceptional place in Poznań, a city located in western Poland. The church is often used as a concert venue. It underwent an acoustic study with the use of a sound source situated in the presbytery and on the pulpit. The aim of this paper is to present results of acoustic investigations and to compare its acoustic properties with other churches. Acoustic parameters acknowledged as primary values used to assess acoustic properties of a religious building were investigated and then compared with recommended values. Placement of the source in two measurement points rendered it possible to carry out speech intelligibility analyses for a variable position of the sound source, and, in effect, enabled functional assessment of the historic pulpit. Thus obtained results were compared with European Baroque churches whose parameters are available in the literature.

Built environment of Polish cities, both external and internal is polluted not only with chemical and physical harmful particles, but also with a number of diversified, continuous sounds, which may in substantial way negatively affect psychological and physical well-being of humans. Moreover, in extreme situations sound may damage vital organs of organisms and at daily occasions negative exposure may cause a number of problems in a longer time perspective. Noise produced by traffic, loudness of school brakes, shouts and car-horns, humming of air condition devices and ducts, air traffic, plus many more, are exposing city users not only on shorter or longer hearing losses, but also on vibration of internal organs and raising of overall anxiety. At the same time, cities are also filled with positive sounds, which allow to lower the blood pressure, calm and relax residents, like: birds singing, leaves and rain humming, water floating, and so on. Hence, this article was devoted towards presentation of research outcomes on pursuit for ‘cleaner’ and higher quality of sound environment in everyday city, in order to create safer and more ergonomic permanent, day-to-day living conditions.

Zbudowane środowisko polskich miast, zarówno zewnętrzne, jak i wewnętrzne, jest zanieczyszczone nie tylko szkodliwymi cząstkami chemicznymi i fizycznymi, ale także szeregiem zróżnicowanych dźwięków, które w istotny sposób mogą negatywnie wpłynąć na dobrostan psychiczny człowieka. Co więcej, w ekstremalnych sytuacjach dźwięk może fizycznie uszkodzić ważne organy organizmu, a w warunkach codziennych negatywna stała, choć niewielka ekspozycja może powodować wiele problemów zdrowotnych, rozwijających się w dłuższej perspektywie czasowej. Hałas powodowany przez ruch, głośność przerw szkolnych, buczenie urządzeń klimatyzacyjnych i wiele innych, naraża mieszkańców miasta nie tylko na krótko- lub długoterminowe ubytki słuchu, ale także na wibracje narządów wewnętrznych i wzrost ogólnego niepokoju. Jednocześnie miasta są również wypełnione korzystnymi dźwiękami, które pozwalają obniżyć ciśnienie krwi, uspokoić i zrelaksować mieszkańców, takimi jak: śpiew ptaków, szum liści i deszczu, przepływanie wody itp. Ten artykuł został poświęcony prezentacji wyników badań dotyczących dążenia do czystszego i wyższej jakości środowiska dźwiękowego we współczesnym mieście w celu stworzenia stałych, bezpieczniejszych i bardziej ergonomicznych codziennych warunków życia.

Two optimization aspects of the meshless method (MLM) based on nonsingular radial basis functions (RBFs) are considered in an acoustic indoor problem. The former is based on the minimization of the mean value of the relative error of the solution in the domain. The letter is based on the minimization of the relative error of the solution at the selected points in the domain. In both cases the optimization leads to the finding relations between physical parameters and the approximate solution parameters. The room acoustic field with uniform, impedance walls is considered. As results, the most effective Hardy’s Radial Basis Function (H-RBF) is pointed out and the numer of elements in the series solution as a function of frequency is indicated. Next, for H-RBF and fixed n, distributions of appropriate acoustic fields in the domain are compared. It is shown that both aspects of optimization improve the description of the acoustic field in the domain in a strictly defined sense.

An efficiency of the nonsingular meshless method (MLM) was analyzed in an acoustic indoor problem. The solution was assumed in the form of the series of radial bases functions (RBFs). Three representative kinds of RBF were chosen: the Hardy’s multiquadratic, inverse multiquadratic, Duchon’s functions. The room acoustic field with uniform, impedance walls was considered. To achieve the goal, relationships among physical parameters of the problem and parameters of the approximate solution were first found. Physical parameters constitute the sound absorption coefficient of the boundary and the frequency of acoustic vibrations. In turn, parameters of the solution are the kind of RBFs, the number of elements in the series of the solution and the number and distribution of influence points. Next, it was shown that the approximate acoustic field can be calculated using MLM with a priori error assumed. All approximate results, averaged over representative rectangular section of the room, were calculated and then compared to the corresponding accurate results. This way, it was proved that the MLM, based on RBFs, is efficient method in description of acoustic boundary problems with impedance boundary conditions and in all acoustic frequencies.

Large venues and auditoriums are commonly associated with their astounding architecture. Their acoustic quality is an essential factor in its qualification as a great and functional, or a badly designed place. However, acoustics is often overlooked during the design stage of a building due to the complexity and high cost of the measurements involved. For this reason, it is important to explore more accessible ways to implement acoustics evaluations. The aim of this work is to compare typical experimental measuring methods and the use of mobile devices to assess the acoustic quality of a room. These measurements are contrasted with the software simulation of the same acoustical space. The results show that the mobile system can be used for professional measurements with low restrictions in the frequency range of interest of this study (90 Hz to 4000 Hz).

Listening tests have been carried out to quantify the significance of binaural auralization over monaural auralization in accordance with the acoustic properties of the enclosure. To this end, acoustic rendering of three different rooms were generated based on synthesized monaural (two channels with the same audio material) and binaural room impulse responses. The auralizations were evaluated by means of subjective tests using headphones with non-individualized equalization. Parameters, such as localization, spatial impression and realism, were taken into consideration to determine the relevance of providing binaural information for the auralization of a given room. The analysis of the data has been conducted following a statistical approach based on ANOVA and Pearson correlation. The results indicate that spatial perception is strongly dependent on the acoustic characteristics of the rooms and on the listening condition of the audio material. Furthermore, as expected, advantages of binaural rendering in terms of source localization was also confirmed.

An efficiency of the nonsingular meshless method is analyzed in an acoustic indoor problem. The solution is assumed in the form of the series of radial bases functions. The Hardy’s multiquadratic functions, as the bases, are taken into account. The room acoustic field with uniform, impedance walls is considered. The representative, rectangular cross section of the room is chosen. Practical combinations of acoustic boundary conditions, expressed through absorption coefficient values, are considered. The classical formulation of the boundary problem is used. It is established any coefficient in the multiquadratic functions depend on the number of influence points, the frequency and the absorption coefficient. All approximate results are calculated in relation to the exact ones. This way, it is proved that the meshless method based on the multiquadratic functions is simple and efficient method in the description of the complicated acoustic boundary problems for the low and medium ranges of frequency.

The Fourier method is applied to the description of the room acoustics field with the combination of uniform impedance boundary conditions imposed on some walls. These acoustic boundary conditions are expressed by absorption coefficient values In this problem, the Fourier method is derived as the combination of three one-dimensional Sturm-Liouville (S-L) problems with Robin-Robin boundary conditions at the first and second dimension and Robin-Neumann ones at the third dimension. The Fourier method requires an evaluation of eigenvalues and eigenfunctions of the Helmholtz equation, via the solution of the eigenvalue equation, in all directions. The graphic-analytical method is adopted to solve it It is assumed that the acoustic force constitutes a monopole source and finally the forced acoustic field is calculated. As a novelty, it is demonstrated that the Fourier method provides a useful and efficient approach for a room acoustics with different values of wall impedances. Theoretical considerations are illustrated for rectangular cross-section of the room with particular ratio. Results obtained in the paper will be a point of reference to the numerical calculations.
