Opis:
Hałas niskoczęstotliwościowy (w tym infradźwiękowy) jest jednym ze szkodliwych i uciążliwych czynników środowiska pracy i życia człowieka. Dominującym efektem wpływu infradźwięków i dźwięków o niskiej częstotliwości na organizm podczas ekspozycji zawodowej jest ich działanie uciążliwe, występujące już przy niewielkich przekroczeniach progu słyszenia. Obowiązujące w środowisku pracy w Polsce (przede wszystkim dla warunków przemysłowych) wartości dopuszczalne hałasu infradźwiękowego ustalone są ze względu na szkodliwość tego hałasu dla zdrowia (głównie oddziaływanie infradźwięków na słuch i cały organizm). Brak jest kryterium dotyczącego uciążliwości hałasu infradźwiękowego i niskoczęstotliwościowego w środowisku pracy. Szczególnie mocno dostrzegane jest to na stanowiskach pracy, na których wykonywane są prace koncepcyjne. W artykule przedstawiono wyniki badań uciążliwości hałasu niskoczęstotliwościowego i infradźwiękowego, głównie na stanowiskach pracy, na których wykonywane są prace koncepcyjne, bądź wymagającej silnej koncentracji uwagi. Badania prowadzono w warunkach laboratoryjnych na modelowym stanowisku pracy.
Low-frequency noise (including infrasound noise) is one of the most harmful and annoying factors in the working and living environments. Annoyance, present even when the audibility threshold is only slightly exceeded, is the dominating effect of low-frequency and infrasound noise during occupational exposure. Infrasound noise values permissible in the working environment (especially for industrial conditions) are established due to the health damaging effect of this sound (mainly the influence of infrasound noise on hearing and on the entire body). At the moment there are no criteria concerning the annoyance of low-frequency and infrasound noise in the working environment. This is especially noticeable at work stations where mental work is taking place. This article presents the results of an analysis of annoyance produced by low-frequency noise at work stations where mental work is taking place, or great attention or concentration are required. Tests were conducted in a laboratory at a model work station.

Opis:
Infradźwięki są naturalnym zjawiskiem w świecie, a hałas infradźwiękowy powszechnie występuje w pobliżu dróg komunikacyjnych i w środowisku miejskim. W ostatnich latach znacznie wzrosło zainteresowanie infradźwiękami, zarówno ze względu na rozwój technologii wytwarzających infradźwięki i rosnący odsetek populacji eksponowany na ten hałas, jak i licznych niejasności z nim związanych. Z fizycznego punktu widzenia infradźwięki niczym nie różnią się od dźwięków słyszalnych czy ultradźwięków. Są zmianami ciśnienia rozchodzącymi się w postaci fal akustycznych w środowisku materialnym: ciałach stałych, cieczach i gazach. W niniejszym artykule będą rozważane tylko dźwięki rozchodzące się w powietrzu. Podział fal dźwiękowych na infradźwięki, dźwięki słyszalne i ultradźwięki wynika z tradycji i ma swoje korzenie w historycznych już badaniach wrażliwości narządu słuchu w funkcji częstotliwości, gdy skalę dźwiękową, z uwagi na ówczesne możliwości aparatury generującej sygnały akustyczne, podzielono na dźwięki słyszalne od 20 do 20 000 Hz i dźwięki niewywołujące u człowieka wrażenia słuchowego. Zaliczenie dźwięków o częstotliwościach < 20 Hz do dźwięków niesłyszalnych było podyktowane także i tym, że badane osoby określały słyszenie dźwięków z tego zakresu, nie jako słyszenie tonów w „normalnym” sensie, lecz raczej jako odczucie „ucisku” w uszach czy dudnienie, buczenie, a ponadto sygnały o niskich częstotliwościach najpierw były odbierane przez receptory drgań (Moore 1999). Ponadto, zarówno w przypadku dźwięków < 20 Hz, jak i dźwięków > 20 000 Hz problemem były, ograniczone wówczas, technicznie możliwości wytworzenia dźwięków o pożądanych parametrach. Dźwięki o częstotliwości poniżej 20 Hz nazywa się infradźwiękami (w niektórych pracach za górną gra-nicę infradźwięków przyjęto częstotliwość 16 Hz), a dźwięki o częstotliwościach powyżej 20 000 Hz nazwano ultradźwiękami (w niektórych pracach za dolną granicę ultra-dźwięków przyjęto częstotliwość 16 000 Hz). Istnieje wiele źródeł emitujących dźwięki o częstotliwościach poza zakresem 20 ÷ 20 000 Hz zarówno naturalnych, jak i antropogenicznych.
Infrasound is traditionally defined as low-frequency sound that is inaudible. Infrasound is acoustic energy with a frequency below 16Hz or 20 Hz and both frequency limits are used. There is no agreement regarding a definition of infrasonic noise. According to Polish standard PN-N-01338:1986, noise whose spectrum consists of sounds with frequencies below 50 Hz is called infrasonic noise, but in literature the term low-frequency noise is more common and 250 Hz is usually considered its upper-frequency limit. Besides a natural origin sources of infrasound like volcanoes, tornados, snow avalanches or less intensive ones like sounds of some animals, etc., there are many human origin sources, e.g., air transport, heavy trucks, compressors, ventilation, air-conditioning systems and more recently wind farms. The latter are spreading as alternative renewable sources of energy. That is why interest in infrasound has recently in-creased. Infrasound, contrary to traditional opinion about its inaudibility, is perceived by our body through our hearing organ and perception via mechanoreceptors has been reported when the infrasound is sufficiently strong. Its audibility depends on the acoustic pressure level and re-quires a much higher level than in the conventional range (20 ÷ 20000 Hz). Infrasound at an extreme high level above 175 dB induces aural pain and could destroy the middle and inner ear (eardrum rupture occurs at 185 ÷ 190 dB). Exposure to infrasound induces temporary threshold shift of hearing. Data on permanent hearing effects are scarce and this problem requires further research. The vestibular organ seems to be sensitive. There are some studies reporting that exposure to infrasound elicits nystagmus (eye movements) from both animals and humans and can result in nausea and giddiness. Subjects exposed to infrasound at a high level (above 130 dB) have reported body vibration. In the region of 40 ÷ 80 Hz the lungs, and below 10 Hz the chest, head and abdomen are resonated. Some results on infrasound were the basis for acoustic weapons. The most prominent effect of infrasound is annoyance, especially in non-occupational exposure but extra-aural effects of exposure are very large in dependence of levels, frequency, circumstances and the subject’s sensitivity. The following have been reported: temporary changes in EEG, sleep disturbances, changes in the cardiovascular system and blood pressure, changes in the digestive and endocrine systems and many others. Tiredness, drowsiness, reduction in concentration ability and performance have been shown as well. Experiments with animals supported human results, however, summing up there are many inconsistencies between the results of different research centres. For over 25 years a team led by Alves-Pereira and Castelo Branco has published many papers on the vibroacoustic disease (VAD). According to their hypothesis exposure to low-frequency noise causes many pathological changes called VAD. The list of symptoms is long, starting with mood and behavioral abnormalities that are early findings related to stage 1 of VAD through in-creased irritability and aggressiveness, a tendency for isolation, depressions and decreased cogni-tive skills to psychiatric disorders, hemorrhages, ulcers, neurological problems, muscle pain and many others at VAD stage III. So far, nobody other than Alves-Pereira and Castelo Branco’s team has reported VAD. Therefore, their hypothesis seems to be original but controversial. Lack or scarcity of evidence should be filled by multicenter research based on scientific methods including epidemiological studies. Some problems with the effect of infrasound on human have resulted from the inconsistency in various authors’ measurements of low-frequency noise. There are some regulations related to infrasound and low-frequency noise, e.g., in Sweden, France, Russia, New Zealand and recently Poland. There is also a recommendation of the American Conference of Governmental Industrial Hygienists for ceiling levels of infrasound in occupational settings. Besides, some countries established national criteria for low-frequency noise in the environment or indoors (Denmark, the Netherlands, Germany, the UK, Sweden and Po-land). Summarizing, it should be emphasised that further research on the health effect of infrasound on human are necessary; especially the hypothesis of VAD should be investigated by multi-center research to be confirmed or refuted. Research should be performed using standardized methods of measurement and equipment. So nowadays to establish TLVs for low-frequency noise in occupational settings further research is necessary.

Opis:
The aim of the study was to investigate how the time structure of a road-traffic affects the noise annoyance judgment. In a psychoacoustic experiment, the listeners judged noise annoyance of four road-traffic noise scenarios with identical numbers of vehicles and LAeq;T value but different time structure of a road traffic. The traffic structure varied from even to highly clustered across different scenarios. The scenarios were created in the laboratory from a large set of a single vehicle passby recordings. The scenarios were additionally filtered with filters corresponding to a typical window transfer function to simulate the situation inside the building. The experimental results showed that there is a significant difference in annoyance judgment for different traffic structures with the same LAeq;T value. The highest annoyance ratings were obtained for even traffic distribution and the most clustered distribution resulted in the lowest annoyance rating. These results correlated well with the averaged loudness, whereas the percentile loudness (N5) and level (L5) predict the opposite results.

Opis:
The assessment of teachers’ exposure to noise in primary schools was carried out on the basis of: questionnaire studies (covering 187 teachers in 3 schools), noise measurements at the teachers’ workplaces, measurements of the school rooms acoustic properties (reverberation time and speech transmission index STI in 72 classrooms), analysis of statistical data regarding hazards and occupational diseases in the education sector. The studies have shown that noise is the main factor of annoyance in the school environment. Over 50% of questioned teachers consider noise as annoying and near 40% as very annoying or unbearable. A-weighted equivalent continuous sound pressure levels measured in classrooms, teacher rooms and common rooms are in the range of 58–80 dB and they exceed 55 dB (criteria of noise annoyance). The most frequently reported subjective feelings and complaints (over 90%) are: growth of psychical and emotional tension, irritation, difficulties in concentrating, hoarseness, cough. Noise in schools is also a harmful factor. High A-weighted equivalent continuous sound pressure levels ranging from 80 to 85 dB, measured in corridors during pauses and in sports halls, can cause the risk of hearing damage among PE teachers and persons oversensitive to noise. The latter concerns both teachers and pupils. High background noise levels (55–65 dB) force teachers to raise their voice. It can lead to the development of an occupational disease – chronic voice disorders due to excessive vocal effort lasting for at least 15 years. In the education sector 785 new cases of this disease were reported only in 2008. Poor acoustics in classrooms (reverberation time ranging from 0.8 to 1.7 s, STI < 0.6 in 50% of classrooms) have an adverse influence on speech reception and make the teaching and learning processes difficult.

An important aspect in assessing noise in urban agglomerations is the subjective one, which takes into account the sensitivity and specific reactions of residents to the noise in their living environment. This paper presents results of a sociological study initiated to determine the population awareness, regarding the urban acoustic environment and estimation of effects and disturbance. The survey was conducted in a Romanian city, to complement the information provided by the strategic noise map of the area. This approach allows the estimation of specific local patterns of reaction and response to urban noise of the exposed population and provides the information, needed to develop action plans and to set proper solutions for urban area planning.

This paper describes the results of a study aimed at developing and validating a prediction model to assess the annoyance conditions at the operator station of compact loaders by using noise signal objective parameters only. For this purpose, binaural measurements were carried out on 41 compact loaders, both in stationary and real working conditions. The 62 binaural noise recordings were objectively analysed in terms of acoustic and psychoacoustic parameters and then divided into 9 groups and used in specific jury tests to obtain the subjective annoyance scores. Finally, multiple regression technique was applied to the first 6 groups of noise stimuli to develop the model while the remaining groups were used to validate it.

Opis:
Zgodnie z definicją WHO [20], zdrowie to nie tylko całkowity brak choroby, czy kalectwa, ale także stan pełnego, fizycznego, umysłowego i społecznego zadowolenia. Zapachy natomiast powodować mogą dyskomfort, irytację, bóle głowy, mdłości, problemy z koncentracją, brak apetytu, bezsenność czy stres [1, 11]. Dlatego też uciążliwość zapachową można zdefiniować jako szkodliwą dla zdrowia poprzez powtarzające się odczuwanie niechcianych zapachów. Pomimo przeprowadzonych badań związanych z oceną uciążliwości zapachowej Polsce nie udało się do tej pory stworzyć uregulowań prawnych dotyczących tego zagadnienia [10, 12, 14, 15]. W wielu krajach na całym świecie istnieją normy dotyczące zapachów (Niemcy, Holandia, Kanada, Australia). Funkcjonuje europejska norma EN 13725 dotycząca określenia stężenia zapachu metodą olfaktometrii dynamicznej, a także jej polska wersja PN EN 13725. Normy te dotyczą jednakże emisji odorów. Do tej pory, natomiast, nie udało się na skalę europejską wprowadzić podobnych standardów odnośnie badan imisji zapachu i jakości powietrza atmosferycznego.
Poland has not managed to create regulations on the odour nuisance assessment in spite of studies related to this issue. In many countries around the world e.g. in Germany, Netherlands, Canada, Australia, there are standards relating to odours. For several years, operates the European standard EN 13725 for the determination of odour concentration by dynamic olfactometry, and its Polish version PN-EN 13725. However, these standards relate to odour emission. So far, there are no similar standards for odour in ambient air (odour imission) and air olfactory quality assessment on a European scale. The legal basis for air quality in Germany is the Act on Protection of At-mospheric Air (German BImSchG: Bundes-Immissionsschutzgesetz). According to it (§ 3 (1)) deterioration of the environment due to pollution, which, because of the nature, size and duration, can cause harm, serious injury or annoyance to the public. Only under this Act a odour nuisance as environment pollution may be viewed. Each plant obtaining licenses for the operation or control of already existing plants is obliged to assess the extent to which the possible nuisance can be considered as serious. So guidelines for "Odour in the air" were developed. In these guidelines, the methods of dealing in relation to immission odour measurement methods and requirements for air olfactory quality are presented: inter alia, the limits of recognized odours in the areas around the industrial plants. The limit values were obtained basing on carried out measurements, comparative tests of the impact and odour frequency and level assessed on the basis of surveys in accordance with VDI 3883. According to GOAA (Guideline on Odour in Ambient Air), the smell can be characterized by its type, the level of feelings - above the threshold of recognition, and through the so-called 'odour hour'. Lack of regulation and standardized terminology relating inter alia to odour measurements in the field is definitely a basic limitation when trying to apply methods of odour assessing in Poland. Therefore, there is a need to clarify the concepts of 'odour imission' (odour in ambient air) and 'survey'. The first of them allows an assessment of frequency of the odour occurrence, is also called 'field research / inspections / measurements'. However, as a 'survey' (question-naires) is defined odor nuissance assessment. The term 'field research' refers to the total assessment of odour with both the imission measurements and questionnaires. Currently, the only way to carry out research in and around a potential odour emission source is the good will of the representatives of the plant. However, the vast majority of traders fear field measurements, since the results of measurements would suggest a potential need for changes and improvements in technology of the industrial plant, which undoubtedly would impose a large financial outlay. Further restrictions apply to conduct research themselves. On one hand, the measurements do not require any complicated or expensive equipment. On the other, are indispensable to the people creating the panel, who should be trained and then perform measurements, which require financial resources. Another problem of a formal nature, is a law on the protection of per-sonal data. Impossible or difficult access to the population database of potential respondents from the area could lead to a significant reduction in the quality of research results and their lack of credibility. However, taking into account the very complex nature of the problem of odour nuisance, and particularly the influence of 'no olfactory' factors, odour evaluation process should be expanded just a survey. Thus, in this study modifications to the German methodology have been done in order to develop evaluation process of the air olfactory quality assessment. It has been concluded that the legislation related to odours should be introduced in Poland in order to improve the evaluation of the problem and finding the optimal deodoration solution.

Opis:
During operation, construction machines generate high noise levels which can adversely affect the health and the job performance of operators. The noise control techniques currently applied to reduce the noise transmitted into the operator cab are all based on the decrease of the sound pressure level. Merely reducing this noise parameter may be suitable for the compliance with the legislative requirements but, unfortunately, it is not sufficient to improve the subjective human response to noise. The absolute necessity to guarantee comfortable and safe conditions for workers, requires a change of perspective and the identification of different noise control criteria able to combine the reduction of noise levels with that of psychophysical descriptors representing those noise attributes related to the subjective acoustical discomfort. This paper presents the results of a study concerning the “customization” of a methodology based on Sound Quality for the noise control of construction machines. The purpose is to define new hearing-related criteria for the noise control able to guarantee not only reduced noise levels at the operator position but also a reduced annoyance perception.

Analizie olfaktometrycznej GC-MS poddano gaz surowy oraz gaz oczyszczony za pomocą instalacji plazmowo-katalitycznej. Nie znaleziono korelacji między stężeniem zapachowym a stężeniami zanieczyszczeń. Postawiono tezę, że disiarczek dimetylu mógły być wskaźnikiem, jednak wymaga to potwierdzenia dalszymi badaniami.
Pollutants, which could be an indicator in the design, choosing and monitoring of odour abatement installation of waste gases from wastewater treatment plants were searched. Crude waste gas and gas purified by the plasma-catalytic system were analyzed using the olfactometric and GC-MS methods. A correlation between odour concentration and concentration of individual pollutants was not found. A thesis that dimethyl disulfide could be the indicator was put forward but it should be confirmed by further studies.

The paper presents results of three socio-acoustic surveys conducted in an interval of twelve years, between 2001 and 2013, in a large Romanian city, Cluj-Napoca. The purpose of the surveys was to assess the awareness of residents on urban noise and the extent to which the noise environment affects their everyday life, behavior and health. The surveys were conducted in 2001, 2009 and 2013. The questionnaire used in the first survey had 16 questions and it was verified prior to study through a pilot survey, being corrected and improved. For the second and the third study, the questionnaire was enriched with eight more questions, regarding essentially the description of the residential area, criteria for its selection and also awareness about the noise map of the city. The analysis of responses defines the main characteristics of the local pattern of annoyance and reaction of the urban population to the environmental noise.

Opis:
A questionnaire inquiry on response to wind turbine noise was carried out on 361 subjects living in the vicinity of 8 wind farms. Current mental health status of respondents was assessed using Goldberg General Health Questionnaire GHQ-12. For areas where respondents lived, A-weighted sound pressure levels (SPLs) were calculated as the sum of the contributions from the wind power plants in the specific area. Generally, 33.0% of respondents were annoyed outdoors by wind turbine noise at the calculated A-weighted SPL of 31–50 dB, while indoors the noise was annoying to 21.3% of them. The propor- tion of subjects evaluating the noise produced by operative wind turbines as annoying decreased with increasing the distance from the nearest wind turbine (27.6% at the distance of 400–800 m vs 14.3% at the distance above 800 m, p < 0.016). On the other hand, the higher was the noise level, the greater was the percentage of annoyed respondents (14.0% at SPL up to 40 dB vs 28.1% at SPL of 40–45 dB, p < 0.016). Besides noise and distance categories, subjective factors, such as general attitude to wind turbines, sensitivity to landscape littering and current mental health status, were found to have significant impact on the perceived annoyance. About 50% of variance in annoyance rating might be explained by the aforesaid subjective factors.

Opis:
Objectives: The overall aim of this study was to evaluate the perception of and annoyance due to the noise from wind turbines in populated areas of Poland. Material and Methods: The study group comprised 156 subjects. All subjects were asked to fill in a questionnaire developed to enable evaluation of their living conditions, including prevalence of annoyance due to the noise from wind turbines and the self-assessment of physical health and well-being. In addition, current mental health status of the respondents was assessed using Goldberg General Health Questionnaire GHQ-12. For areas where the respondents lived, A-weighted sound pressure levels (SPLs) were calculated as the sum of the contributions from the wind power plants in the specific area. Results: It has been shown that the wind turbine noise at the calculated A-weighted SPL of 30-48 dB was noticed outdoors by 60.3% of the respondents. This noise was perceived as annoying outdoors by 33.3% of the respondents, while indoors by 20.5% of them. The odds ratio of being annoyed outdoors by the wind turbine noise increased along with increasing SPLs (OR = 2.1; 95% CI: 1.22-3.62). The subjects' attitude to wind turbines in general and sensitivity to landscape littering was found to have significant impact on the perceived annoyance. About 63% of variance in outdoors annoyance assessment might be explained by the noise level, general attitude to wind turbines and sensitivity to landscape littering. Conclusions: Before firm conclusions can be drawn further studies are needed, including a larger number of respondents with different living environments (i.e., dissimilar terrain, different urbanization and road traffic intensity).
