“…The majority of statistical analyses referring to random dispersion of the test results use an assumption that random variable has a normal distribution. The literature data concerning outdoor noise reveal that long-term noise indicators do not have a normal distribution (Batko, Stępień, 2014;Przysucha et al, 2020;Wszolek, 2006). Conversely, it must be accepted that the random variable distribution in the presented cases is related to the special character of the traffic noise variability.…”

Indoor noise can greatly affect the health and comfort of users, so the significance of the right assessment of the compliance with the requirements is obvious. But noise level testing is carried out using different methods, which may not ensure consistency in assessmentsThe paper presents the influence of test methods on measurement results determined based on an analysis of inter-laboratory comparative studies. The analyses presented in the paper apply to an equivalent sound pressure level determined for a permanent source of sound -an air-conditioning device. The test methods were characterised according to their precision. In order to compare them, their compatibility was analysed based on the methodology described in the literature, alongside a single-factor analysis of variance. It was determined that there were no grounds for rejecting the hypothesis about lack of statistical differences between the results obtained via different methods. Each of the methods is characterised by different precision, so consequently the same result obtained with each method carries a different risk in regards to noise assessment.The reason for taking up this kind of research was the decision of the Polish Technical Committee in 2018 about introducing new acoustic requirements in Poland concerning the admissible indoor sound pressure levels. It was decided to implement new international methods of testing indoor sound pressure levels emanating from the service equipment in the building. It was necessary to show the differences between the current method and its new counterparts.

This paper determines the influencing factors of architectural acoustic environment comfort assessment from the perspective of green building acoustic environment comfort, and constructs a two-by-two comparison judgment matrix for each questionnaire survey result. Through the consistency test of the judgment matrix, the weights of the factors influencing the comfort of the building sound environment are obtained, and the construction of the assessment model of the comfort of the building sound environment is completed. Based on the architectural acoustic environment comfort assessment model, optimization variables are selected and multi-objective optimization is used to determine the objective function and constraints of architectural acoustic environment comfort. The comfort of the acoustic environment of the campus building is evaluated and analyzed through simulation analysis. The results show that the two measurement points, point 8 and point 15, located on the north side of the library and information building and the center courtyard, respectively, have relatively low continuous sound pressure levels L eq of 51.7 dB and 44.4 dB, respectively, which are relatively favorable for the creation of a comfortable acoustic environment. Improving the building arrangement through the multi-objective optimization method under the acoustic environment assessment model can provide good environmental protection for people’s daily lives and work.

“…The following description could be considered as a definition of uncertainty in the acoustic measurements: "a parameter related to the measured result, characterising the scatter of results, which can be reasonably attributed to the measured value" [1,2]. This sentence states that uncertainty estimation corresponds to an approximate description of the imperfections of the experiments.…”

Within the frame of SIPARIO, a project recently funded by the Italian region Emilia Romagna, it aims to virtually reconstruct both 3D audio and 360° video of real performances by recording and undertaking acoustic measurements inside the most historical theatres and concert halls spread all over the Europe. However, the measurement of multi-channels IRs is influenced by several other factors, including thermo-hygrometric conditions. This paper deals with the experimental analysis concerning the influence of temperature, relative humidity, and air velocity on acoustic parameters. Thermo-hygrometric variables have been varied and the variation of several room acoustic parameters has been analized. The data have been collected in order to obtained a relation between the variation of the acoustic parameters with the variation of the thermo-hygrometric variables. In further steps, a statistical analysis will be conducted to determine possible correlations between room acoustic parameters and thermohygrometric parameters.
