Opis:
The Environmental Noise Directive (END), published in 2002, was transposed into Romanian local law in 2005, and it was the starting point for the first urban noise mapping exercises, initially conducted in nine Romanian cities. This paper presents the main evolutionary aspects of the noise assessment process, the development of strategic noise maps, and action plans, dealing with both the legislative side and the practical approach and results obtained. The study considers the specific regulations established by the European Commission regarding environmental noise assessment and deals with the global context at the country level, in which they have been implemented and applied.

Opis:
The paper presents a comparison analysis of the noise generated by wind turbines and the one generated by a ventilation shaft of a working coal mine. The aim of the research was to compare the frequency and amplitude distribution of those sources, especially in the infra range. The ultimate aim it is evaluate possible environmental impact on human annoyance or severity. During the research noise signals were recorded utilizing low frequency microphones, shielded by windscreens. Microphones were localized at the heights of 0.0 m, 1.5 m (approximate location of a human ear in a standing position) and 4 m. Additionally, a measurement position of a microphone in relation to the ground surface was observed. Measurements at ground level were performed according to the standard PN-EN 61400-11:2013-07 and in vertical position, where the microphone was mounted "upside down" with the grid flush with the board. The possible influence of wind speed was also monitored. The results of the measurements are discussed.

Opis:
Aim of the study was to asses noise annoyance in relation to psychoacoustic metrics of sound in an office environment. The Vienna Test System was used for this purpose. Virtual office acoustic environments were developed with sources of different psychoacoustic parameters (loudness, sharpness, fluctuation strength, roughness) but with a constant A-weighted sound pressure level of 55 dB - sound environment with conversations, sound environment with office equipment (computers, printers, telephones) and sound environment with all office noise sources together. The reference environment was a quiet office room with no additional noise sources. Recorded real noise sources were transferred to a virtual 3D sound environment and converted into binaural sound, which was then played back on headphones. During the exposure to each of the acoustic environments, the subjects performed the ALS test (work performance series) and COG test (measurement of attention and concentration) and then assessed the given environment using a questionnaire. The paper presents the results of the statistical analysis - despite different psychoacoustic metrics of office noise sources in the examined acoustic environments, no statistically significant differences were observed in the results of psychological tests.

Opis:
Amplitude modulation increases the annoyance caused by wind turbine noise. One gets the improved annoyance when a penalty is added to the measured or calculated time-average sound level. The amplitude modulated wind turbine noise consists of pulses. Each of them could be characterized by the short time-average sound level and the modulation depth. The latter determines the pulse penalty. This paper shows how to calculate the improved annoyance of amplitude modulated wind turbine noise, when the short time-average sound level and the penalty for each pulse are known. A special case of identical pulses is discussed. The proposed methodology needs to be tested by research.

Opis:
Noise mapping is based on long-term noise indicators, such as LN or LDEN. On the other hand, transportation intensity changes during a day (road traffic peak hours) or a year (more flights during holidays) and this variability is not reflected in single sound level values. We wanted to find out whether not only sound level but also the number of noise events is the factor influencing noise annoyance assessment. Ambisonic recordings of real traffic in a city were used. Road, tramway, and aircraft traffic were investigated and two factors were manipulated: the equivalent sound level value and the number of noise events. All stimuli were presented in an anechoic chamber. The results showed that sound level is always a statistically significant parameter while the number of events has an impact only for tramways and airplanes. Moreover, the difference is observed only between one or more subgroups, no matter what the sound level value was. For road traffic this relation was not found to be statistically significant. It was also shown that the existence of tramway bonus or airplane malus is linked with the number of noise events.

Opis:
Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing. Like air pollution, noise pollution is one of the serious matters of concern in urban areas. Noise pollution occurs when noise level exceeds certain limit and has deleterious effects on human health and wellness. The major sources of noise pollution are industries, road traffic, railways, airplane traffic and social celebrations. The traffic noise is notably high in cities due to higher density of population, frequent movement of people, good transport system coupled with increasing numbers of vehicles (on road). In this work, the assessments of traffic noise in Sambalpur city is presented. Twelve important locations were chosen for the assessment. Noise contours were drawn to visualize the spreading of traffic noise into its surroundings. At the same time, the effect of noise pollution on wellness of the exposed people was studied. The study shows that the traffic noise level and its effects, are both in an alarming stage in the city.

Opis:
Annoyance is the most prevalent community response to environmental noise. Observational and experimental lab studies have shown that exposure to environmental noise leads to annoyance, sleep disturbance, daytime sleepiness, increased heart rate and increased blood pressure. However, previous literature is preliminary based on controlled settings or experimental design, raising the question of the generalizability and applicability in daily life scenarios. This study aimed to investigate two main research questions. First, what is the relationship between short-term annoyance and different amounts of nocturnal aircraft noise exposure in daily life? Second, what is the relationship between physiological parameters, including heart rate, number of awakenings, sleep efficiency, sleep duration and different amounts of nocturnal aircraft noise exposure in daily life? This study also aimed to explore the suitability of non-invasive commercially available activity trackers to measure physiological metrics in a scientific way. During this field study, participants were wearing Fitbit Charge 3 activity trackers recording heart rate and different sleep-derived metrics (e.g. deep sleep duration, sleep efficiency and awakenings). The used activity trackers were readily available, non-intrusive, relatively cheap and easy to use by the participants. Simultaneously, a logbook was used by the participants to track the subjective perception and situational context of air traffic noise exposure. The noise levels corresponding to the exposure of air traffic of each participant were calculated based on the location of the participant and the corresponding radar track using an aircraft noise monitoring system. We hypothesize that a higher amount of exposure to aircraft noise in real life will be associated with increased annoyance, increased rest heartrate, higher number of awakenings, decreased sleep efficiency and decreased deep sleep duration.
Znużenie jest najbardziej rozpowszechnioną reakcją społeczności na hałas w środowisku. Obserwacyjne i eksperymentalne badania laboratoryjne wykazały, że ekspozycja na hałas środowiskowy prowadzi do irytacji, zaburzeń snu, senności w ciągu dnia, podwyższonego tętna i podniesionego ciśnienia krwi. Jednakże, wcześniejsza literatura opiera się wstępnie na ustawieniach kontrolowanych lub projektach eksperymentalnych, podnosząc kwestię uogólnienia i możliwości zastosowania w scenariuszach życia codziennego. To studium miało na celu zbadanie dwóch głównych kwestii badawczych. Po pierwsze, jaka jest zależność między krótkotrwałym znużeniem a różnymi liczbami nocnego hałasu emitowanego przez samoloty w życiu codziennym? Po drugie, jaka jest zależność między parametrami fizjologicznymi, w tym tętnem, liczbą przebudzeń, efektywnością snu, czasem trwania snu a różną ilością narażenia na hałas emitowany przez nocne samoloty w życiu codziennym? Badanie to miało również na celu zbadanie przydatności nieinwazyjnych, dostępnych na rynku urządzeń śledzących aktywność, do naukowego pomiaru parametrów fizjologicznych. Podczas tego badania terenowego uczestnicy nosili urządzenia śledzące aktywność Fitbit Charge 3, rejestrujące tętno i różne wskaźniki fizjologiczne (np. czas trwania głębokiego snu, efektywność snu i przebudzenia). Użyte rejestratory aktywności były łatwo dostępne, nieinwazyjne, stosunkowo tanie i łatwe w użyciu przez uczestników. Jednocześnie uczestnicy korzystali z dziennika rejestrującego w celu śledzenia subiektywnego postrzegania i kontekstu sytuacyjnego narażenia na hałas wytwarzany przez ruch lotniczy. Poziomy hałasu odpowiadające narażeniu na ruch lotniczy każdego z uczestników zostały obliczone na podstawie lokalizacji uczestnika i odpowiadającego mu toru radarowego z wykorzystaniem systemu monitorowania hałasu lotniczego. Zakładamy, że większe narażenie na hałas emitowany przez samoloty w warunkach rzeczywistych będzie wiązało się ze zwiększonym znużeniem, zwiększonym tętnem spoczynkowym, większą liczbą przebudzeń, zmniejszoną efektywnością snu i zmniejszonym czasem trwania głębokiego snu. Wstępne wyniki dotyczące interakcji między narażeniem na hałas emitowany przez samoloty, postrzeganym znużeniem i parametrami fizjologicznymi sugerują, że zwiększona nocna ekspozycja na hałas emitowany przez samoloty wydaje się negatywnie wpływać na efektywność snu i czas trwania głębokiego snu.

Opis:
The noise perceiving issue is very subjective and depends on several factors, such as: the living environment in which each person has grown and developed, the education they have received, the culture in which their life principles have formed and, last but not least, the social and financial status. Therefore, in order to establish effective actions in multiple directions when it comes to any urban noise analysis, it is very important to know the perception and the subjective reactions of the individuals involved. The paper respects this idea, presenting the results of a sociological study on urban noise, applied in the city of Cluj-Napoca, Romania. The intention was to capture the reactions of the permanent residents of the city, but also of the people in transit, as well as to analyse the changes that occurred as result of the implementation of the Environmental Noise Directive (European Commission). The study shows that 75.2% of the respondents consider that the noise in the city has increased in the last ten years and 58% of tchem have rated the noise as level 4 or 5 on a five point scale. Information related to noise maps and actions taken to reduce community noise has no sufficient dissemination. There is also a medium to low reaction of the population in correlation to the declared noise annoyance.

Opis:
Noise exposure is one of the most important physical agents in the workplace which can induce job stress in several ways. The aim of this study was to model the interactions between independent and mediating variables and job stress using structural equation modeling. In this study, Weinstein’s noise sensitivity scale, noise annoyance questionnaire, Health and Safety Executive (HSE) job stress questionnaire and job satisfaction scale were used. To assess worker’s noise exposure, the 8-hours equivalent continuous A-weighted sound pressure level (LAeq;8 h), was measured based on ISO 9612 (2009). To achieve the aims of study, the structural equation model was run using R software 3.4.1 and Cytoscape software 3.6.0. Based on the results, while there was a direct positive correlation of noise exposure on total job stress, there were also indirect positive effects through job satisfaction and noise sensitivity as mediator variables. Using hearing protective devices negatively affected total job stress through a direct pathway and an indirect pathway when job satisfaction was a mediator variable. Regarding the total effect of noise exposure and using hearing protection devices on job stress subscales, it can be concluded that noise exposure and using hearing protection devices had greatest effect on colleagues support and demand, respectively. It can be concluded that noise exposure and lack of hearing protective devices have a significant positive effect on job stress among workers of a textile industry. In addition to the direct effect, this factor can induce job stress through noise sensitivity, job satisfaction and noise annoyance. Therefore, measures which can decrease any of the mentioned factors, also can alleviate job stress.

Opis:
The present study aimed to determine the role of job components and individual parameters on the raised blood pressure among male workers of textile industry who were exposed to continuous high noise level. Information of all eligible subjects including demographic and individual characteristics, medical history and job characteristics were obtained by direct interview and referring to the medical records. All blood pressure measurements were done using mercury sphygmomanometer in the morning before work. The 8-hours equivalent A-weighted sound pressure level, the level of blood cholesterol and triglyceride, and noise annoyance was determined for each worker. As the result of weighted regression in path analysis (direct effect), only the work shift did not have a significant effect on blood pressure among the studiem variables. It can be seen that variables including the level of triglyceride, cholesterol, and noise exposure have the most direct effects on blood pressure. The results of total effects showed that variables, including using the hearing protection device, age, work experience and visibility of sound source, did not have a significant effect on blood pressure. The results of this study indicate that occupational noise exposure alone and combined with other job components and individual parameters is associated with raised blond pressure. However, noise exposure was probably a stronger stressor for increased blood pressure.

Opis:
A pumped storage power plant produces significant noise such that adjacent areas were deemed uninhabitable for the local population. In recent years, the population in the area has increased, and the noise levels are now causing significant distress to the local population. The company operating the power plant and a citizens’ initiative have both commissioned noise measurements. The measurements showed that the continuous pump noise was audible over many kilometers. The A-weighted sound-pressure level of 50 dBA at the next residential area underestimates the perceived noise, given the clear tonal nature in the low frequency range. Interviews of the exposed population, together with detailed “annoyance diaries” by a sample of the residents, proved their high level of annoyance. Their reported observations on distress and sleep disturbances coincide with the time course of the pumping operation. The pumping noise leads to annoyance in a large area, and to considerable nuisance in a smaller one. For the most exposed homes, long-term exposure might be considered a health hazard due to stress and disturbances in sleep quality. Therefore, the operator committed to developing a technical noise control plan. This case shows that a scientific approach within a complex environmental noise problem can foster an agreement about noise protection measures. However, this can only be successful if all involved parties participate in the process. Pilot studies are underway to test the impact of damping material layers on the pipes, the housing of the pipes, and the kind of air vessel solutions between the pumps and the pipes.

As a primary objective of this study, data were evaluated in the areas of advertising perception and the relationship between gender-generational characteristics was pointed out (generation Y and Z), moreover the selected types of advertising were mentioned. The types of advertising (advertising on TV, social networks, etc.) can acquire various forms (most annoying, most trusted, etc.) in gender-generational characteristics, which can affect the reputation of the organization. The data were obtained through a questionnaire research. The sample consisted of 296 responses. The data collection was implemented in early 2018. A significant difference was found in the perception of advertising in all dimensions among the categories of gender-generational characteristics except the 'most memorable'. Differential analysis was carried out, where significant differences occurred in a number of cases. Furthermore, a correspondent analysis was applied, in which the areas of perceptions of advertising had shown very close relations in several cases. The disadvantage of the research is that it is realized only in Slovakia.
Jako główny cel tego badania oceniono dane w zakresie postrzegania reklamy oraz wskazano związek między cechami pokoleniowo-płciowymi (pokolenie Y i Z), ponadto wymieniono wybrane rodzaje reklamy. Rodzaje reklam (reklama w telewizji, portale społecznościowe itp.) mogą przybierać różne formy (najbardziej irytujące, najbardziej godne zaufania, itp.) w cechach płciowych, które mogą wpływać na reputację organizacji. Dane uzyskano za pomocą badań ankietowych. Próbka składała się z 296 odpowiedzi. Gromadzenie danych zostało wdrożone na początku 2018 r. Znaczącą różnicę stwierdzono w postrzeganiu reklamy we wszystkich wymiarach wśród kategorii cech pokoleniowych, z wyjątkiem "najbardziej zapadających w pamięć". Przeprowadzono analizę różnicową, w której znaczące różnice wystąpiły w wielu przypadkach. Ponadto zastosowano analizę korespondencyjną, w której obszary percepcji reklamy w kilku przypadkach wykazywały bardzo bliskie relacje. Wada badań polega na tym, że jest ona realizowana tylko na Słowacji.

Opis:
Tasks requiring intensive concentration are more vulnerable to noise than routine tasks. Due to the high mental workload of bank employees, this study aimed to evaluate acoustic comfort in open-space banks based on speech intelligibility and noise annoyance metrics. Acoustic metrics including preferred noise criterion (PNC), speech transmission index (STI), and signal to noise ratio (SNR) were measured in seventeen banks (located in Hamadan, a western province of Iran). For subjective noise annoyance assessments, 100-point noise annoyance scales were completed by bank employees during activities. Based on STI (0.56±0.09) and SNR (20.5±8.2 dB) values, it was found that speech intelligibilities in the workstations of banks were higher than the satisfactory level. However, PNC values in bank spaces were 48.2±5.5 dB, which is higher than the recommended limit value for public spaces. In this regard, 95% of the employees are annoyed by background noise levels. The results show irrelevant speech is the main source of subjective noise annoyance among employees. Loss of concentration is the main consequence of background noise levels for employees. The results confirmed that acoustic properties of bank spaces provide enough speech intelligibility, while staff’s noise annoyance is not acceptable. It can be concluded that due to proximity of workstations in open-space banks, access to very short distraction distance is necessary. Therefore, increasing speech privacy can be prioritised to speech intelligibility. It is recommended that current desk screens are redesigned in order to reduce irrelevant speech between nearby workstations. Staff’s training about acoustic comfort can also manage irrelevant speech characteristics during work time.

The obtained results may be used in the acoustic quality modeling the acoustic quality of the urban environment at risk of noise.
W artykule przedstawiono próbę oceny statystycznej wyników badań psychoakustycznych z przeprowadzonego eksperymentu nad dokuczliwością źródeł hałasu drogowego. Badaniu podlegała ocena dokuczliwości hałasowej emitowanych sygnałów akustycznych w warunkach laboratoryjnych. Otrzymane wyniki badań wykorzystane mogą być w zadaniach modelowania jakości akustycznej środowiska zurbanizowanego zagrożonego hałasem.
