    Opis:
    The paper presents the new solution to a road acoustic screen consisting of elements which are highly diffusing and simultaneously resistant to weathering, but also characterised by a sound absorption. There is described the comprehensive research of such the road acoustic screen with absorbing and diffusing surface. The study includes screen’s resistance to wind load and snow removal, impact tests and measurements of some acoustic parameters.

    Opis:
    Due to the current shortage of traditional public space because of its privatization, commercialization, and securitization, there is an urgent need to reclaim areas affected by motorized traffic in the urbanized areas. On the other hand, the process of adapting them for new purposes should be carefully carried out, addressing several issues, among them environmental acoustics. This study is meant to contribute to our understanding of acoustic conditions of a general model of the bridge underspace. Therefore, the aim of the research was to examine the existing acoustic climate by measuring noise levels and comparing them with equivalent acceptable noise levels for the expected type of space development and Noise Rating curves. In this research, a pilot case study approach was used, as measurements were taken for a chosen space located under an elevated road that represents certain criteria set by the researchers. The results allowed us to: (1) verify the relationship between the geometry of the bridge underspace and the noise levels, (2) assess the initial acoustic conditions in terms of possibilities of acoustic adaptation of the examined space for outdoor public events, and (3) formulate hypotheses and preliminary assumptions for the planned further and broader studies of the issues raised in this article. The presented results and their analysis show that it is possible to bring the acoustic conditions in the studied space to the state required for public or cultural meeting spaces. In comparison with earlier findings, the research undertaken appears to be pioneering and the results can be used as valuable input for further research on this topic.

    Opis:
    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.

    Opis:
    The specific working conditions of the wind turbine in strong wind cause a number of problems in the measurement of noise indicators used in its short and long-term assessment. The wind is a natural working environment of the turbine, but it also affects the measurement system, moreover, it can be a secondary source of other sounds that interfere with the measurement. One of the effective methods of eliminating the direct impact of wind on the measurement system is placing the microphone on the measurement board at ground level. However, the obtained result can not be directly compared with the admissible values, as it has to be converted to a result at a height of 4 m. The results of previous studies show that this relation depends, inter alia, on the speed and direction of the wind. The paper contains the results of measurements on the measurement board, according to EN 61400-11:2013, and at a height of 4 m above ground made simultaneously in three points around the 2 MW turbine at various instantaneous speeds and changing wind directions. Analysis of the impact of measuring point location on the measurement result of noise indicators and the occurrence of additional features affecting the relationship between the values measured on the board and at the height of 4 m, and especially the tonality, amplitude modulation and content of low frequency content, was made.

    Opis:
    Zgodnie z obecnie obowiązującym prawem podczas wprowadzania inwestycji budowlanej do środowiska jej skala, zastosowane rozwiązania projektowe oraz technologia realizacji obiektu mogą podlegać ocenie środowiskowej. Artykuł przedstawia analizę prognozowanego oddziaływania hałasu i światła, jakie może się pojawić w trakcie codziennej eksploatacji budynków mieszkalnych na obszarze całego osiedla oraz na terenach z nim sąsiadujących. W tym celu wykorzystano dostępne narzędzia komputerowe przy pomocy, których opracowano model sytuacji dla projektowanego osiedla a na jego podstawie, przeprowadzono symulacje przedstawiające rozkład światła i pola akustycznego w sąsiedztwie analizowanego osiedla domów jednorodzinnych.
    Under current law, when entering a construction project to the environment, its scale and the applied design solutions and technology implementation shall be subject to peer review. This article presents a reference to the applicable acoustic requirements concerning the environment. The paper presents the acoustic analysis of the forecasted impact that may arise during the particular phases of construction works and after the completion of the project, during everyday exploitation of the buildings in the whole housing estate. The research part of the paper comprises the analysis of noise impact on the protected areas neighboring with the project in view of the scope and methods of the construction works carried out under the schedule. For this purpose, in the program Soundplan, model variants of the construction works were worked out as well as the target situation, where after the simulations of the distribution of the acoustic field in the vicinity of the project were carried out.
