Abstract and Figures

Physical stressors like noise can have a significant impact on both the environment and the health of people who are exposed to it. In particular, the excessive noise produced by road traffic is a highly topical issue. The study aimed to investigate the traffic noise values on a busy road in the town of Turzovka. In addition to comparing the measured results with the limit values, we conducted a questionnaire survey with fifty residents. The questionnaire surveyed the attitudes of fifty town residents towards traffic noise concerning their quality of life and health. Subsequently, we compared the questionnaire survey results with the measured noise values at a measured site on a busy road in Turzovka. The respondents' answers from the questionnaire survey confirmed that 68% of the respondents felt the impact of noise exposure on their health, which corresponded with the results of the accurate measurements. According to the measurements, the critical time zones were from 5:00 to 6:00 and from 16:00 to 17:00. The final part of the thesis consists of the proposed measures, whose implementation can decrease the potential high noise exposure and thus reduce the health risks associated with the noise issue.

Abstract Physical stressors like noise can have a
significant impact on both the environment and the
health of people who are exposed to it. In particular,
the excessive noise produced by road traffic is a highly
topical issue. The study aimed to investigate the traffic
noise values on a busy road in the town of Turzovka. In
addition to comparing the measured results with the
limit values, we conducted a questionnaire survey with
fifty residents. The questionnaire surveyed the
attitudes of fifty town residents towards traffic noise
concerning their quality of life and health.
Subsequently, we compared the questionnaire survey
results with the measured noise values at a measured
site on a busy road in Turzovka. The respondents'
answers from the questionnaire survey confirmed that
68% of the respondents felt the impact of noise
exposure on their health, which corresponded with the
results of the accurate measurements. According to the
measurements, the critical time zones were from 5:00
to 6:00 and from 16:00 to 17:00. The final part of the
thesis consists of the proposed measures, whose
implementation can decrease the potential high noise
exposure and thus reduce the health risks associated
with the noise issue.

1. Introduction
Noise is a physical factor that is responsible for
several other damages to health in addition to
damage to the hearing organ. Among the most
important manifestations are a decrease in quality,
disorders of psychosocial well-being [1], [2].
Unlike other physical factors, people perceive
noise by a specific auditory system. Thus, it is a
phenomenon everyone perceives and evaluates,
which is why noise exposure is one of the most
common, if not the most frequent, complaints of
residents living in large cities [3], [4]. Traffic is the
most frequently cited noise source in these cities and
their surroundings [5].
Many studies have focused on the generation of
road traffic noise [6], addressing the effect of
roadway type on annoyance to residents [7], [8].
Other authors have addressed annoyance when
considering traffic characteristics [9], [10], motorised
two-wheelers, and heavy vehicles [11], [12], but have
also taken into account the influence of road surface
type.
A noise risk assessment system is based on the
relationship between noise exposure levels and the
likelihood of adverse health effects. [13], [14].
In 2011, the WHO published research on the
burden of disease from environmental noise. The
survey resulted in data on the loss of healthy years in
people due to environmental noise [15], [16].
Based on the research, information was obtained to
quantify the noise burden for cardiovascular diseases,
cognitive disorders in children, sleep disorders,
tinnitus, and crankiness [17], [18].
According to research, after air pollution,
environmental noise is the second most important
factor contributing to the morbidity of society [19],
[20], [22].

The European survey on quality of life in 2016-
2017 on a sample of 37,000 respondents from all EU
member states and five candidate countries
confirmed that one third of respondents (32%) have
problems with environmental noise [23], [21].
Countries, regions, and cities are taking various
measures to tackle noise-related problems. In order to
reduce and limit noise, roads are paved with anti-
noise asphalt, cities are building more infrastructure
for electric vehicles, quiet tyres are preferred for road
transport, streets are transformed into pedestrian
zones, and parks and nature reserves are created [24].
In Slovak legislation, the permissible noise levels
for road transport (Laeq,p) are set by Decree No
549/2007 Z. z. (Table 1).

The study's main objective was to determine the
level of noise pollution from traffic in the town of
Turzovka by accurate measurements (screening) and
to compare the results of the measurements with the
maximum permissible values. By asking the
inhabitants of Turzovka, we obtained their opinions
on the noise burden and their subjective perception of
environmental noise and its harmful effects on their
health and well-being.
Turzovka is a small town in the northwest of
Slovakia with 7121 inhabitants. It is located near the
border with the Czech Republic, and the road from
Čadca to the Czech border village of Makov runs
around it. It is a Class II road number 487, a crucial
traffic junction with high traffic frequency and with
an assumption of an increased level of noise
pollution (Figure 1).
Figure 1. Geographical location of Turzovka
(https://www.enviroportal.sk/indicator/detail?id=521)
2. Methods
The study was conducted in two stages. In the first
stage, real measurements were taken in the village of
Turzovka. In the second stage, a questionnaire survey
of residents was carried out, in which they expressed
their opinion, how they perceive environmental noise
and its impact on their health.
2.1. Design of Experimental Measurement
The determination of the noise measurement sites
preceded the actual experimental measurement.
Therefore, by observing the number of cars during
the day, we determined the location and the time
periods for measuring. We took into account the
following aspects:
- the crossroads of the main road Makov - Čadca
and the contact with the main road to the Czech
Republic;
- a specific place the boundary of the first
inhabited house;
- measurement time at the highest noise load
(highest number of passing cars).
A graphical view of the measurement site is in
Figure 2.

We made the measurements using a compact noise
meter type UNI T UT353 (UNI-TREND
TECHNOLOGY, CO., LTD., China), designed to
measure and control the noise level in buildings,
outdoor areas, in the vicinity of residences, near
highways, railway lines, or even performs loudness
measurements of various equipment. The specific
measuring instrument is shown in Figure 3, and
Table 2 presents its technical parameters.

We carried out the measurements over two days
(29 November 2022 and 30 November 2022), during
which the temperature ranged between 8 and 10 °C
during the day and between 3 and 4 °C in the
morning and evening hours. The hours of the
measurements taken are in Table 3.

3rd measurement
The noise level meter was placed 2m from the road
boundary and at a height of 1.5m from the ground
(Figure 2). We recorded measurement values every 5
minutes. The measurements also included road traffic
intensity.
We divided the different types of vehicles into
trucks over 3.5 tonnes (including suburban public
transport), the next group was vans up to 3.5 tonnes
and, in the last group were cars.
3. Results
Figure 4 shows the results of the measurements of
the equivalent noise level averaged in dB (Laeq,p)
including the number of personal cars in the
distribution of cars over 3.5 tonnes, vans under 3.5
tonnes and cars.
Figure 4. Measured values of noise exposure concerning
road traffic frequency and time of measurements
The results show that not only trucks but also cars
or several aspects such as vehicle speed, engine type,
vehicle speed, road type, and asphalt quality
influence the noise level. We found exceeding the
permissible noise level for the reference time (day)
set at 60 dB, with 74.3 dB and 71.7 dB recorded in
the 5:00 - 6:00, 71.7 dB in the 6:00 - 7:00 and 70.4
dB in the afternoon, from 16:00 - 17:00 time periods
respectively.
4. Questionnaire Survey
People from the town of Turzovka were contacted
at the site of the noise measurements to express their
opinion on how they perceive the noise exposure
from traffic. The questionnaire consisted of 14
questions, of which one was open-ended, and three
questions were 5 Likert-scaled. The scaling was as
follows: 1 - noise does not bother me; 2 - noise does
not bother me, but I perceive it; 3 - noise bothers me,
but I can stand it; 4 - noise bothers me to a
considerable extent; 5 - noise bothers me to a great
extent, I cannot stand it.

Each digit represents the subjective strength of the
respondent's attitude concerning all questions about
the noise burden issue.
The sample of respondents consisted of 50
inhabitants of Turzovka, of which 52% were women
and 48% were men. The return rate of the
questionnaire was 100%, and we preserved the
anonymity of the respondents. According to their
age, we divided the respondents into the following
age groups:
- age up to 26 years ‒ 30% of respondents,
- age from 26 to 62 years 50% of respondents,
and
- over 62 years ‒ 20% of respondents.
In terms of occupation, 26 (52%) were retired,
students and mothers on maternity leave, 4 residents
(8 %) were not working, 8 (16%) respondents were
doing mental work, and 12 (24%) were doing manual
work.
Among the questions asked, we also surveyed the
type of housing. 31 respondents (62%) reported
living in a house on the first floor, 19 respondents
(38%) lived in a flat, of which 9 (18%) reported
living on the 1st floor, 5 (10%) reported living on the
2nd floor, and 5 (10%) reported living on the 3rd
floor. These results also represent the composition of
houses and flats in Turzovka, where housing in
family houses dominates, especially in the urban
districts. One question in the questionnaire asked
about the orientation of bedrooms. As many as 48
(96%) respondents indicated that such rooms are
oriented in the street with heavy traffic.
The next question focused on the respondents'
views on where they felt the most noise disturbance.
They answered on a Likert scale from the following
options: at work, home, school and outdoors. We
present the results of the responses (respondents
could also indicate more than one option) in Table 4.

There is a significant impact of noise exposure on
residents in both the home and school environments,
but most so in the outdoor environment, with up to
45 respondents agreeing. In another response, 40
(80%) of respondents identified traffic as the most
significant source of noise, 5 (10%) of respondents
identified work-related noise, and 5 (10%) of
respondents identified noise from outdoor industrial
sources. These results are consistent with noise
measurements carried out on a busy road.
Subsequently, we aimed to specify the periods the
respondents perceived as significant concerning the
impact of noise burden on their organism. These
results, subjected to comparative analysis with
accurate measurements, result from subjective
perceptions with observed noise values. Figure 5
presents these results.
Figure 5. Time of day periods identified by respondents as
the most bothersome for environmental noise [26]
Up to 40 (80 %) of respondents said that noise
annoyed them between 5:00 and 10:00. The next
critical period of the day is between 18:00 and 20:00,
which was identified by up to 45 (90%) respondents
as the period during which they experience noise
disturbance. The results are compatible with the
obtained measurements. We measured the highest
traffic intensity and noise burden values in these time
intervals, namely from 5:00 to 6:00 - up to 74.3 dB,
when the equivalent noise level was exceeded until
7:00 when the average noise level reached 71.7 dB.
In the afternoon, we also recorded a noise burden as
high as 70.4 dB.
The final questions in the questionnaire were
devoted to the adverse effects of noise on public
health. The most common health problems
mentioned by the respondents were sleep
disturbance, mentioned by 18 (36%) of the
respondents, and hearing impairment by 15 (30 %) of
the respondents. We cannot overlook concentration
disorders in work performance reported by 9 (18%)
respondents, mainly young people under 26 years. Of
the sample of respondents who had health problems,
18 residents (i.e. up to 52% of the respondents) had
to seek medical attention. Nine respondents need to
take medication for sleep disorders in the long term.
According to the questionnaire results, residents
would welcome effective measures to reduce noise in
the town. Firstly, up to 33 (66%) of respondents
would welcome a reduced traffic volume in the town.
25 (50%) respondents favoured the construction of
noise barriers, and 22 (44%) respondents demanded a
reduction in the maximum speed limit.

15 (30%) would welcome measures such as road
reconstruction, soundproof windows, and other
construction solutions.
5. Conclusion
The result analysis shows that the classification of
urban traffic noise depending on the frequency of
vehicles is annoying and disturbing for the
inhabitants of Turzovka. In the overall analysis of the
results, 25% of the measurements were higher than
60 dB(A), which shows that traffic noise is a
significant pollutant even in such a small non-
industrial city. The results showed a clear
relationship between urban traffic noise and traffic
volume.
The questionnaire results indicate that up to 34
(68%) of citizens feel the impact of noise exposure
on their health. In selecting the types of health
problems to include in the questionnaire, we drew on
information on the health problems of Europeans
obtained from the EEA European studies mentioned
in Chapter 1 and from the 2015 survey by the Slovak
Republic's Public Health Office [27]. Of our research
sample, up to 34 (52%) respondents also had to see a
doctor, and some are also taking medication for
noise-related problems such as sleep disturbances
and hearing impairment.

Conference Paper
Full-text available
Noise reduction for urban areas, especially noise generated by traffic is one of the major problems in today's European cities. This paper is focused on more aspects that are addressing to traffic noise, like pavement, driver's behavior, frequency of stops, pick hours, traffic agglomerations, etc. Research leading to this paper was conducted within the project " Adaptation to the Climate Change " developed in partnership with Environmental protection Agency Sibiu, focusing for this case study on traffic related pollution in a historical city center of Sibiu. Were considered three types of pavements (cobblestones, streets covered with dense asphalt, and graded asphalt road surfaces), three types of vehicles (small passenger car, family car and SUV), and testing's were done using 3M Quest SoundPro Sonometer. Higher noise levels were registered for cobblestone and dense asphalt surfaces. Acoustic measurements and maps emphasizing studied are presented, and the identified parameters considered to be related to the traffic noise are given.

Background: Environmental health effects vary considerably with regard to their severity, type of disease, and duration. Integrated measures of population health, such as environmental burden of disease (EBD), are useful for setting priorities in environmental health policies and research. This review is a summary of the full Environmental Burden of Disease in European countries (EBoDE) project report. Objectives: The EBoDE project was set up to provide assessments for nine environmental risk factors relevant in selected European countries (Belgium, Finland, France, Germany, Italy, and the Netherlands). Methods: Disability-adjusted life years (DALYs) were estimated for benzene, dioxins, secondhand smoke, formaldehyde, lead, traffic noise, ozone, particulate matter (PM2.5), and radon, using primarily World Health Organization data on burden of disease, (inter)national exposure data, and epidemiological or toxicological risk estimates. Results are presented here without discounting or age-weighting. Results: About 3-7% of the annual burden of disease in the participating countries is associated with the included environmental risk factors. Airborne particulate matter (diameter ≤ 2.5 μm; PM2.5) is the leading risk factor associated with 6,000-10,000 DALYs/year and 1 million people. Secondhand smoke, traffic noise (including road, rail, and air traffic noise), and radon had overlapping estimate ranges (600-1,200 DALYs/million people). Some of the EBD estimates, especially for dioxins and formaldehyde, contain substantial uncertainties that could be only partly quantified. However, overall ranking of the estimates seems relatively robust. Conclusions: With current methods and data, environmental burden of disease estimates support meaningful policy evaluation and resource allocation, including identification of susceptible groups and targets for efficient exposure reduction. International exposure monitoring standards would enhance data quality and improve comparability.

A meta-analysis of 14 studies (17 individual effect estimates) on the association between road traffic noise and coronary heart diseases was carried out. A significant pooled estimate of the relative risk of 1.08 (95% confidence interval: 1.04, 1.13) per increase of the weighted day-night noise level L DN of 10 dB (A) was found within the range of approximately 52-77 dB (A) (5 dB-category midpoints). The results gave no statistically significant indication of heterogeneity between the results of individual studies. However, stratified analyses showed that the treatment of gender in the studies, the lowest age of study subjects and the lowest cut-off of noise levels had an impact on the effect estimates of different studies. The result of the meta-analysis complies quantitatively with the result of a recent meta-analysis on the association between road traffic noise and hypertension. Road traffic noise is a significant risk factor for cardiovascular diseases.

Background: Exposure to environmental noise is associated with adverse health effects, but there is potential for confounding and interaction with air pollution, particularly where both exposures arise from the same source, such as transport. Objectives: To review evidence on confounding and interaction of air pollution in relation to associations between environmental noise and cardiovascular outcomes. Methods: - Papers were identified from similar reviews published in 2013 and 2015, from the systematic reviews supporting the WHO 2018 noise guidelines, and from a literature search covering the period 2016-2022 using Medline and PubMed databases. Additional papers were identified from colleagues. Study selection was according to PECOS inclusion criteria. Studies were evaluated against the WHO checklist for risk of bias. Results: - 52 publications, 36 published after 2015, were identified that assessed associations between transportation noise and cardiovascular outcomes, that also considered potential confounding (49 studies) or interaction (23 studies) by air pollution. Most, but not all studies, suggested that the associations between traffic noise and cardiovascular outcomes are independent of air pollution. NO2 or PM2.5 were the most commonly included air pollutants and we observed no clear differences across air pollutants in terms of the potential confounding role. Most papers did not appear to suggest an interaction between noise and air pollution. Eight studies found the largest noise effect estimates occurring within the higher noise and air pollution exposure categories, but were not often statistically significant. Conclusion: Whilst air pollution does not appear to confound associations of noise and cardiovascular health, more studies on potential interactions are needed. Current methods to assess quality of evidence are not optimal when evaluating evidence on confounding or interaction.

Background: Recent years have seen growing, but still tentative, evidence of the potential associations of environmental noise and air pollution with mental disorders. In the present study, we aimed to examine the associations between residential noise and air pollution exposures and general mental health in young adults with a focus on underlying processes METHODS: We sampled 720 students (18-35 years) from one university in the city of Plovdiv, Bulgaria. Residential noise (LAeq; day equivalent noise level) and air pollution (NO2) were assessed at participant's residential address by land use regression models. General mental health was measured with a short form of the General Health Questionnaire (GHQ). The following putative mediators were considered: annoyance from environmental pollution, sleep disturbance, restorative quality of the neighborhood, neighborhood social cohesion, and commuting/leisure time physical activity. Structural equation modeling was used to analyze the theoretically-indicated interplay between exposures, mediators, and GHQ. Results: We observed an association between higher LAeq and GHQ, in which environmental annoyance and neighborhood restorative quality emerged as key mediators. First, LAeq was associated with higher annoyance, and through it with lower restorative quality, and then in turn with lower physical activity, and thus with higher GHQ. Simultaneously, higher annoyance was associated with higher sleep disturbance, and thereby with higher GHQ. NO2 had no overall association with GHQ, but it was indirectly associated with it through higher annoyance, lower restorative quality, and lower physical activity working in serial. Conclusion: We found evidence that increased residential noise was related to mental ill-health through several indirect pathways. Air pollution was associated with mental health only indirectly.

The negative impact of noise on human health is well established and a high percentage of environmental noise is related with traffic sources. In this study, we compared annoyance judgments of real and virtual traffic sounds. Virtual sounds were generated through an auralization software with input from close proximity tyre/road noise measurements and real sounds were recorded through a Head and Torso Simulator. Both groups had sounds generated at two speeds and from three urban pavement surfaces (asphalt concrete, concrete blocks and granite cubes). Under controlled laboratory conditions, participants rated the annoyance of each real and virtual stimulus.

Noise maps are diagnosis tools which represent the noise exposure situation using the energy-based index Lden (the day-evening-night level). Two major drawbacks may be attributed to noise maps: (1) energy-based indices only account for one acoustical factor (exposure level) that may give rise to annoyance; (2) combined exposures situations are left unframed. In order to contribute to the overcoming of these flaws, two laboratory experiments were undertaken. Experiment 1 consists in listening tests where perceptual and cognitive categories of various urban road vehicle pass-by noises including two-wheeled vehicle pass-by noises are studied from the annoyance point of view. This experiment allows to highlight spectral and temporal features, and to propose noise annoyance indicators based on common acoustical and psychoacoustical indices in order to take these acoustical features into account. Experiment 2 consists in assessing annoyance due to the previous urban road vehicle pass-by noises heard in the presence of a steady industrial noise. Interactions effects are found and attributed to the temporal evolution of combined noises. Perceptual total annoyance models are found to be better models than psychophysical ones. This last result highlights the necessity to continue efforts to improve the characterization of annoyance due to noise in isolation.

Objective: The association between the exposure to road traffic noise and the prevalence of hypertension was assessed accounting for background air pollution and the location of rooms with respect to the road. Methods: A cross-sectional study was carried out inviting all subjects aged 35-74 years for participation that lived on 7 major trunk roads in 3-4 storey terraced apartment buildings and in parallel side streets that were completely shielded from noise due to the rows of houses along the major roads. The study was performed on 1770 subjects that did not have a self-reported medical doctor diagnosis of hypertension before they moved into their current residence. Noise levels at the facade of the front and the rear side of the houses were drawn from available noise maps of the area. A large set of covariates were considered to adjust the results for confounding. Results: Significant increases between road traffic noise and hypertension were found with respect to the 24h A-weighted average noise indicator L(DEN). The adjusted odds ratio (OR) per noise level increment of 10 dB(A) was 1.11 (95% confidence interval (CI): 1.00-1.23). Stronger significant estimates of the noise effect were found in subjects with long residence time (OR=1.20, CI=1.05-1.37), and with respect to the exposure of the living room during daytime (OR=1.24, CI=1.08-1.41) compared with the exposure of the bedroom during night-time (OR=0.91, CI=0.78-1.06). Conclusion: Chronic exposure to road traffic noise is associated with an increased risk of high blood pressure. Daytime noise exposure of the living room had a stronger impact on the association than night-time exposure of the bedroom.
