Exposure to impulsive noise produced by fireworks has a higher level of risk to human health than exposure to continuous noise. Aware of the problems related to this type of exposure, the European Union (EU) published the Directive 2013/29/EU that establishes a maximum sound level of 120 dB(A, imp) at several distances of launching point depending on the type of artefact. The present work aims to investigate the levels of exposure to which the population and workers are exposed when participating in festivals or pilgrimages. This research was done in northern Portugal during summer. Five events were evaluated and parameters such as LAeq, LA10, LA50, LA90 were recorded. In the measurements, the sound level meter was on during the time the explosions occurred, and in one case that was about 30 minutes. During the measurements people of all ages, from babies to seniors, as well as professionals such as musicians, police officers, fire-fighters, merchants and others, were seen without a...

The noise exposure of spectators were measured at three Finnish air shows. Fixed and rotary-wing and both civil and military aircraft performed manoeuvres. The noise evaluation consisted of the total noise description on a minute-by-minute basis, analyses of the maximum sound pressure level of certain events, a noise dose analysis of aircraft manoeuvring displays, and a noise dose analysis of spectators, firemen, first-aid personnel and spectators. The noise doses of the spectators varied from 84 to 92 dB and the maximum levels measured near the spectators ranged from 100 to 115 dB. The noise levels measured during the manoeuvres of jet fighters over the area ranged from 83 to 104 dB. The dose did not exceed current recommended levels for long-time exposure, however, high instantaneous sound pressure levels can cause tinnitus and temporary threshold shift. This type of noise can be unpleasant, and some persons are even sensitive to this kind of noise. Therefore hearing protectors should be available for sensitive persons at air shows.

This paper presents a literature review of scientific production on the theme of 'noise in leisure activities.' Journals in the Virtual Health Library were examined on issues such as noise, occupational noise and noise in leisure activities. The publications reviewed in this study are divided into two categories: effects on hearing, and measurement of sound pressure levels. The findings of the literature review reveal the urgent need to adopt preventive measures and to raise the awareness of public authorities, health and leisure professionals, and the general public about the problem of noise. Simulations of the acoustic descriptor speech transmission index STI were performed in 4 gym academies, and the results show that the quality of communication range from bad to satisfactory, given that noise levels are high.

Government authorities are faced with a number of challenges when attempting to regulate noise from outdoor concerts. A key difficulty is the ability of an authority to meaningfully influence the behaviour of a concert operator during the concert itself. In many jurisdictions, penalties for environmental noise nuisance are an insufficient deterrent-resulting in permit conditions and noise limits being routinely exceeded or ignored. Authorities can also face a regulatory burden where noise conditions are technically difficult to measure, difficult to determine compliance, and require specialised equipment and staff to be available outside standard business hours. Noise regulations need to be carefully determined with the aim of motivating good noise self-regulation without being prohibitively punitive or impractical. Noise limits need to consider the realistic sound levels that are needed to hold a successful concert, while still preventing unreasonable behaviour. This strategy has been implemented by setting noise measurement locations at the sound mixing desk. Mixing desk staff can then monitor their own levels with immediate feedback and corrections where required. Self-monitoring provides industry with the ability to clearly demonstrate responsible behaviour to authorities and the community and it provides certainty and security for future use of the venue.

Negative effects of noise on individuals, the inevitable result of urbanization, have become a significant urban problem in our day. Introduction of an approach to the noise problem on an urban-planning scale lightens the burden of measures required to be taken against noise at the stages of regional and developmental planning. Stadiums, which should be also evaluated from the point of noise problem when planning decisions are made on the urban planning scale, may cause very serious problems differing depending on the region they are located in. In this article, various dimensions of the noise problem caused by stadiums have been exemplified by making an assessment on Ali Sami Yen football stadium located in Mecidiyeköy district which is among important residential and commercial centres oḟ Istanbul or Turkey. When the simulation results obtained for ordinary days and match days are evaluated, it has been found out that the people living in the area are exposed to noise levels sub

The issue of communal noise has been partially resolved on paper by lows and by-lows on the permissible noise levels in the environment. However, the question is how much noise the community will tolerate, ie, at what point citizens will start fighting noise. Numerous cities have signed strict regulations for reducing noise levels, both day and night, with a proposal for permitted limits. This paper presents commonly used methods for managing and protecting against the harmful effects of noise.

Although most research related to urban noise exposure, refers mainly to transportation noise, epidemiological research has already demonstrated the risks of leisure noise exposure, including fireworks, on children, the youth, and young adults thus denoting the need for further investigation. Cumulatively, the general population living near an event's location can also feel disturbed by this type of noise. This study investigated the noise produced by fireworks at events not yet evaluated, indicating the need for better noise management by the organizers, as well as a revision of the recent European Directive in addressing exposure limits for children. The objective of this study was to evaluate the noise exposure of the population of Northern Portugal during fireworks at festivals and pilgrimages. With that purpose, measurements and questionnaires were conducted at 27 non-pyromusical and pyromusical events. Events considered to be the largest or the most traditional events which occur annually in the Northern Region of Portugal. The measurement equipment was a type 1 sound level meter, from 01 dB, positioned at the most exposed point, meaning, the area where the population was closest to the fireworks. The measurement time lasted for the entire duration of the firework explosions. The L Aeq , L Amin , L Amax values, as well as the statistical indicators, L A90 , L A50 , and L A10 , were determined with an impulsive response. The results showed that in 72% of the evaluated events, the exposure level exceeded 120 dB (A, imp), the limit-value defined by the Directive 2013/29 UE. The average L Amax , CI 95% value, for the exposed population when assisting those events, ranged between 121 and 125 120 dB (A, imp). Hypothesis tests performed for this sample, at a significance level of 5%, demonstrated that there is no significant difference between the average exposure for both types of events, nonpyromusical and pyromusical. Considering that these noise levels can induce hearing impairment this study demonstrated the need for noise control measures for the people attending these types of events. Suggested solutions highlight the following safety measures: the use of quiet fireworks, the reduction of music volume at pyromusical events, changes to the public's position and an implementation of public sessions in order to raise the population's awareness about harmful noise effects, particularly for groups that are more sensitive to noise.

Festivals, pilgrimages, and fireworks are part of the Portuguese culture just as they are in a number of other countries. Currently, in Portugal there are>14,000 catalogued events [4]. It was possible to recognize, even with all the restrictions demanded by the present COVID-19 virus, that such events are a major instrument in
