Opis:
A global index of machines was developed to assess noise emitted by machines and to predict noise levels at workstations. The global index is a function of several partial indices: sound power index, index of distance between the workstation and the machine, radiation directivity index, impulse and impact noise index and noise spectrum index. Tests were carried out to determine values of the global index for engine-generator; the inversion method for determining sound power level was used. It required modelling each tested generator with one omnidirectional substitute source. The partial indices and the global index were simulated, too. The results of the tests confirmed the correctness of the simulations.

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 intensive development of sport shooting and the significant increase in the number of people using sport and recreational shooting ranges also increases the risk of hearing damage to shooters, due to exposure to impulse noise from the shots of firearms. This article discusses the methodology for assessing shooters’ exposure to noise and identifies and extensively discusses possible ways to minimise this exposure. It then describes a research experiment carried out to measure and calculate the effectiveness of noise reduction by means of acoustic silencers when shooting with typical weapons in the most popular sporting and hunting calibres. The experiment also included firing tests with subsonic ammunition. On this basis, conclusions were drawn regarding the possibility of reducing impulse noise during shooting and the possibility of eliminating the risk of hearing damage.

Opis:
This work is a contribution to a normative approach of noise assessment in the professional environment. It permits the identification of the affected workstations on the one hand and on the other hand it constitutes an important support to the preoccupations of the impact study on the environment in plants. It also informs us on the adequate preparation of the procedures required by the Environmental Management System (ISO 14001) being implemented in steel-making complex ArcelorMittal Algeria. It constitutes an answer to the recommended environmental politics. The proposed calculation methods are verified according to the recognized sources (ISO 9612, 2009) and the results will be estimated in relation to the legal thresholds recommended by international bodies. The methodology for measuring the noise exposure levels has been done according to the following steps: work analysis; selection of measurement strategy; measurements; error handling and uncertainty evaluations; calculations; and presentation of results. This will lead us to an implementation of a corrective and preventive action plan intended to master this occupational risk carrying prejudice to the health of the workers.

Opis:
Increased efficiency of production and improved quality have contributed to the development of ultrasonic technological applications, in which low frequency ultrasounds are generated to operate, accelerate as well as to facilitate technological processes. Technological ultrasonic devices (i.e. sources of ultrasonic noise in the work environment, e.g. ultrasonic washers, ultrasonic welding machines) have relatively high power and their nominal frequencies are in the range from 18 kHz to 40 kHz. In Poland, ultrasonic noise (defined as noise containing high audible and low ultrasonic frequencies from 10 kHz to 40 kHz) is included in the list of factors harmful to health in the work environment and therefore the admissible values of ultrasonic noise in the workplaces are established. The admissible values of ultrasonic noise and the new ultrasonic noise measurement method make it possible to perform the assessment of occupational risk related to ultrasonic noise. According to this method, the scope of the measurements includes the determination of the equivalent sound pressure levels in the 1/3 octave bands with the centre frequencies from 10 kHz to 40 kHz. This paper presents the description of both, i.e. the method for ultrasonic noise measurements and the method of the assessment of occupational risk related to ultrasonic noise. The examples of the results of the assessment of occupational risk related to exposure to ultrasonic noise are also discussed.

Opis:
Military vehicles are used less intensively than the civil ones, and many types of the vehicles used by the army are stored for a long time. Therefore, this type of vehicles can be used even for a dozens of years. Due to the constant development of technology, used armament and military equipment has to be adjusted to current needs. The above applies also to recovery vehicles, including field workshops. This work analyses the level of safety and comfort of the crew of the modified field workshop (Sarna II) when the vehicle is moving under various conditions. The scope of improvement included two seats inside workshop for the transportation of the crew members. Experimental research involved measuring the accelerations on the seats of the crew and the noise inside the vehicle body. The assessment was conducted on the basis of the highest value of 8-hour of the exposure to the whole body vibrations A(8). The accelerations acting on the seats were determined mainly by the kind of the road, its roughness and the speed of the vehicle. The occupational risk connected with the exposure to the mechanical vibrations was in most cases assessed to be low or moderate. The risk was assessed to be high only when the vehicle was moving on the dirt road. Results of experimental researches indicated that passengers travelling in the body of Sarna II workshop, mounted on the underbody of STAR 266M2 vehicle, have ensured proper conditions of transport, both in terms of exposure to mechanical vibrations and to the noise.

The hazard assessment of ultrasonic noise impact on human body at workplaces presents an open problem; it is not satisfactorily solved comparing the fund of knowledge and standard regulations established for the case of audible noise. Some research carried on in the Central Institute of Labour Protection - National Research Institute, Poland, are essential for elaboration reliable procedures for the assessment of ultrasonic noise hazard and they have to bring to modernization and creation the corresponding standards in this field. In the presentation, some problems related to measurement procedures applied as well as to the interpretation of results essential for hazard assessment of ultrasonic noise impact on human body will be considered; in particular such cases where some procedures elaborated for audible noise assessment are being transferred to apply in the ultrasonic range without taking fully into account some specific aspects of the high frequency components of the noise.

Opis:
Objectives: To determine whether call center dispatchers wearing headsets are subject to auditory fatigue at the end of a work shift. Material and Methods: Data was gathered at times when call centers were busiest. All call operators wore a headset for up to 12 h. Acoustic environment and noise exposure under the headset were continuously recorded during the entire work shift. Variations in auditory parameters were assessed using pure-tone air-conduction audiometry and an objective test based on distortion product otoacoustic emissions – contralateral suppression of distortion product otoacoustic emission (DPOAE) amplitudes (EchoScan test). Thirty-nine operators and 16 controls, all volunteers, were selected from 3 call centers (sales, assistance, and emergency) where all cognitive tasks were accomplished by phone and on computers. Results: No acoustic shock was detected during the investigation. The highest normalized noise exposure (daily noise exposure level – LEX,8 h) measured was 75.5 dBA. No significant variation in auditory performances was detected with either pure-tone air-conduction audiometry or the EchoScan test. Nevertheless, dispatchers expressed a feeling of tiredness. Conclusions: For an equivalent diffuse field noise exposure, the use of a headset does not seem to worsen auditory fatigue for call center operators. The dispatcher’s fatigue was probably due to the duration of the work shift or to the tasks they performed rather than to the noise exposure under a headset.

Opis:
Hałas ultradźwiękowy na stanowiskach pracy w Polsce jest określony jako hałas, w którego widmie występują składowe o wysokich częstotliwościach słyszalnych i niskich ultradźwiękowych. Ocenę narażenia na hałas ultradźwiękowy wykonuje się na podstawie (równoważnego i maksymalnego) poziomu ciśnienia akustycznego w tercjowych pasmach częstotliwości. Jego głównymi źródłami w procesie pracy są technologiczne urządzenia ultradźwiękowe operujące na niskich częstotliwościach. Jednym z rodzajów takich urządzeń są drążarki ultradźwiękowe. W artykule przedstawiono metodę pomiaru i kryteria oceny ekspozycji na hałas ultradźwiękowy na stanowiskach pracy oraz wyniki pomiarów i ocenę ryzyka zawodowego związanego z narażeniem na ten hałas na wybranych stanowiskach obsługi drążarek ultradźwiękowych.
In Poland, ultrasonic noise at workstations is defined as broadband noise with high audible frequencies and low ultrasonic frequencies. Assessment of exposure to ultrasonic noise is based on (equivalent and maximum) sound pressure level in the 1/3 octave band. The main sources of ultrasonic noise in the working environment are for example ultrasonic drills. This article presents a measurement method and criteria for assessing exposure to ultrasonic noise at workstations. The results of measuring ultrasonic noise and risk assessment related to occupational exposure to ultrasonic noise are presented in reference to selected workstations where ultrasonic drills are used.

Opis:
Hałas jest jednym z najpowszechniej występujących szkodliwych i uciążliwych czynników w środowisku pracy. Według danych Europejskiej Fundacji na rzecz Poprawy Warunków Życia i Pracy w UE około 33% ogółu pracujących odczuwa dyskomfort pracy, związany z narażeniem na hałas. W 2015 roku w Polsce w warunkach zagrożenia hałasem pracowało 187,1 tys. osób, co stanowiło 55,1% liczby pracowników zatrudnionych w warunkach zagrożenia szkodliwymi czynnikami środowiska pracy. Największą liczbę osób zatrudnionych w warunkach zagrożenia hałasem w sektorach polskiej gospodarki odnotowano w górnictwie węgla kamiennego oraz przetwórstwie przemysłowym. W artykule poddano analizie rozmiar zagrożenia hałasem w polskim górnictwie oraz w Węglokoks Kraj Sp. z o.o. KWK „Bobrek – Piekary” w aspekcie liczby stwierdzonych chorób zawodowego uszkodzenia słuchu. Autorzy artykułu przeprowadzili badania i pomiary poziomu dźwięku A stosowanych maszyn i urządzeń oraz identyfikację podstawowych źródeł hałasu w kopalni. W artykule poddano również analizie korelację uzyskanych in situ wartości poziomu ciśnienia akustycznego skorygowanego charakterystyką A na stanowiskach pracy w stosunku do określonych w instrukcji producenta parametrów charakteryzujących poziom emisji hałasu maszyny.
Noise is one of the most common harmful and burdensome factors in working conditions. According to data of the European Foundation for the Improvement of Living and Working Conditions, approximately 33% of workmen in the EU feel uncomfortable at work, which is connected with noise. In 2015, in Poland, there were about 187,1 thousand people working in noise hazard conditions, which makes about 55,1% of all the workers employed in conditions which are harmful for the people’s health. The biggest number of people employed in noise hazard conditions in Polish economy sectors was recorded in coal mines and manufacturing. The authors of this paper analyze the size of noise hazard in the Polish mining industry and “Bobrek – Piekary” coal mine in the aspect of occupational hearing loss. The authors of the paper conducted tests and measurements of the sound level of the used machines and equipment as well as identified the basic sources of noise in mines. In the paper, the correlation of the in situ obtained values of the level of the acoustic pressure corrected by the characteristics at the working place in relation to the parameters defined in the producer’s manual, which characterize the level of emitted noise by a machine, was analyzed.

The following article constitutes an attempt to solve the problem of the interpretation of results based on a comparison of measured values to permissible values. When exceeded limits are observed, the recipients of acoustic analyses (mainly non-specialists) are frequently uncertain as to how to interpret the results. At the moment, there is no unambiguous way of defining acceptable, alarming or unacceptable values of noise but an original indicator methodology, which allows a clear and easy interpretation of the results obtained, has been proposed. The suggested noise load factor (NLF), based on measurements of physical quantities, enables conducting a broader assessment of the nuisance of noise originating from railway vehicles.

Opis:
Given the high-power concentration of combustion engines used in military aviation, it is reasonable to measure the instantaneous surges in the sound pressure level. Therefore, a research question was raised regarding the differences in this level for various aircraft engines of the same type (F100-PW-229) to assess their size and statistical significance. The aim of the paper is to discuss the attempt to check the significant difference between the parameters of the acoustic level generated by the aircraft engines. The measurements were carried out for 32 engines of the F-16 Block 52+ multirole aircraft during takeoff process. The parameters of noise in the point system and in the octave distribution were subject to analysis. Statistical methods dedicated to assessing production stability, i.e. the Shewhart chart, were applied. The results of the analysis showed that the discrepancies generally do not exceed a value of +/− 3σ . Therefore, it can be concluded that the analogous results for F-16 noise are homogeneous. Thus, the Shewhart chart method proved useful for assessing the homogeneity of these measurements.

Opis:
A new method of combined assessment of the influence of vibrations (hand-arm and whole-body) and noise hazards simultaneously acting on employees is presented in the paper. The method has been developed on the basis of tests performed in selected means of road transportation. The investigations have shown that separate estimation of individual factors leads to unreasonable omission of a certain part of energy influencing the employee. The suggested assessment method is based on the grounds of adding all kinds of the vibroacoustic energy. The application of this method allows one to take into consideration vibrations and noise occurring simultaneously, and due to this, the significant difference between results of the hazard assessment at workplaces in comparison to results obtained by previously used standardised methods is revealed.
W artykule przedstawiono nową metodę oceny łącznej drgań (miejscowych i ogólnych) i hałasu działających równocześnie na pracowników. Opracowano ją na podstawie wyników badań przeprowadzonych w wybranych środkach transportu drogowego. Badania wykazały, że niezależna ocena działających poszczególnych czynników wiąże się z nieuzasadnionym pomijaniem w ocenie części energii wibroakustycznej docierającej do pracownika. Proponowana metoda oceny opiera się na zasadzie sumowania energii wibroakustycznej. Zastosowanie opisanej metody pozwala na uwzględnienie jednoczesnego działania drgań i hałasu; powoduje to istotne różnice wyników oceny narażenia czynnikami wibroakustycznymi na stanowisku pracy w stosunku do wyników uzyskanych dotychczasowymi metodami znormalizowanymi.

Opis:
Noise induced hearing loss (NIHL) as one of the major avoidable occupational related health issues has been studied for decades. To assess NIHL, the excitation pattern (EP) has been considered as one of the mechanisms to estimate the movements of the basilar membrane (BM) in the cochlea. In this study, two auditory filters, dual resonance nonlinear (DRNL) filter and rounded-exponential (ROEX) filter are applied to create two EPs, the velocity EP and the loudness EP respectively. Two noise hazard metrics are proposed based on two EPs to evaluate hazardous levels caused by different types of noise. Moreover Gaussian noise and single-tone noise are simulated to evaluate performances of the proposed EPs and the noise metrics. The results show that both EPs can reflect the responses of the BM to different types of noise. For Gaussian noise there is a frequency shift between the velocity EP and the loudness EP. The results suggest that both EPs can be used for assessment of NIHL.
