It
is a fact that people used to listen to so many sounds in their daily lives,
and these sounds are necessary as well. But sound becomes an unwanted thing or
which causes a lot of pain and disturbance; then it becomes noise. Noise is a
kind of sound, which creates discomfort in the ears, and a person doesn’t feel
comfortable at all to hear such sounds. This when sound becomes noise
pollution, which can be caused due to various reasons and it can have so many negative
impacts. The balance, as well as comfort of life, is completely disrupted by
the noise pollution. The noise pollution is caused by various means such as
traffic, industrial activities, social events, and household equipment etc. (SUSAN, 2018). It is important to
understand which level of sound is considered as noise. It is known that decibels
(db) parameter is used to measure sound. It has been observed that when two
persons normally make conversation with each other, then sound level measuring is
around 60 db. However, a level of noise is measured beyond 80 db like the heavy
traffic can cause a sound level at 85 db. The research has shown that constant
exposure to noise level beyond 85 db can start to cause serious damages. So if
harmful noise levels are not avoided and prevented, then a person can have
serious health and other issues (Healthwise Staff, 2018)
It
is important to understand different perspective about noise pollution and its
causes & effects through primary research sources. Singh & Davar (2004)
published a research article to identify sources, effects as well as control
measures for noise pollution. The study used cross-section survey method to
collect valuable data, and it was found out that population of Delhi City has
two face tow main causes of noise pollution, one is automobiles, and the other
is loudspeakers. It was also found out that noise made by loudspeakers affected
females more than males. It was also identified that noise pollution had few
severe effects on population such as less efficiency, sleeplessness, disruptive
communication, mental stress as well as deafness. The respondents of this
research study explained that public education should be increased to aware of
noise pollution as it can be one of the best methods to do so. However, it was
also concluded that NGOs along with government authorities could play a major
part in spreading awareness amongst the general public regarding noise
pollution that how it can be dangerous for their society and environment, and
how it can be reduced (Singh & Davar, 2004)
In
other research articles, the researchers focused on the topic of noise as well
as environmental pollution, which is caused by transportation. The study tried
to analyze decisive problems, which are faced by developing transport systems,
which are based on ecology. The primary focus of the paper was to discuss
issues related to transport systems to be developed as sustainable systems, and
special focus is given to ensure that noise pollution along with environmental
pollution is minimize their level. A traffic flow model was presented in the
research to develop a transport network so that the external costs of harmful
emissions and noise can be estimated. It also looked at congestion and any
effects which are related to congestion. The model was also used to measure the
flow of traffic with all its environmental and noise effects with the help of
computational experiments. The numerical example for the study was taken from
the transport network from Poland. It was concluded in the ending part of the
paper that transports systems, which are ecologically efficient; they can
decrease the level of noise as well as pollution created by transport (Jacyn, Wasiak, Lewczuk, & Karoń, 2017)
A research article was published in 2018 regarding
the noise pollution with its causes & effects keeping the case study of
university students from the city of Delhi in India. It was described in the
paper that the level of noise pollution is increasing with the passage of time
due to the noisy urban lifestyle as well as bad management of noise pollution. In
result, noise pollution is making an effect on people by causing various health
& wellness issues. The study was conducted to get a response from college
and university students from Delhi, and it was found out that youth in the city
does have good enough awareness about noise pollution along with its causes and
effects on health. The study also revealed that music, as well as vehicle
noises, were the two most causes of noise pollution in the city. It was
recommended in the end that government and society should play its part in
spreading awareness through awareness campaigns (Ismail & Ahmed, 2018)
Research Hypotheses: The traffic
and vehicles are the most common cause of noise pollution, which develop
various health issues in society.
Methods
to reduce the Noise Pollution
To
test the hypotheses that traffic and vehicles are one of the most common
causes, and people do face health issues due to noise pollution, we used the
survey method to collect data. It is a qualitative research method to collect
data from the respondents taken from a sample population. It is important to mention
here that secondary research methods could have also been used by analyzing
existing research material to see that what findings were made in those
studies, and what were the most common causes of noise pollution. But it was
more appropriate to conduct primary research through proper research design to
collect real-time data from the population. So, for this primary research,
qualitative research method was selected to be the most appropriate method. A
survey questionnaire was developed (See Appendix 1), which was used to collect
relevant answers from the sample population. It is important to mention here
that a sample of 30 people was taken from a community, which was residing near
an urban centre with too much flow of traffic and noise. The sample was taken
to see what they think about this constant noise of traffic and vehicles around
them.
The
other most critical part of the research is to explain its dependent and
independent variables. To identify adequate causes of noise pollution with its
effects on health, noise pollution was taken as a dependent variable. On the
other hand, traffic and vehicles are independent variables. It is essential to
explain why these dependent and independent variables were selected. The noise
pollution was considered a dependent variable because its level can change with
other factors such as the heavy flow of traffic. For instance, during office
hours early in the morning, the traffic influx is heavy, and more vehicles are
on the roads, that’s why more vehicles mean more noise being created, which ultimately
affects the level of noise pollution. During off-peak hours of traffic, when vehicles
are in less number like during midnight, then less traffic comes with less
noise pollution level. It is quite evident that with the independent variable
of vehicles, the value of the dependent variable of noise is being changed in
different situations. As compared to that vehicles are independent variables as
no other factor can change their value in any regard.
The
survey questionnaire did include some personal information of survey respondents
such as their age, gender, and marital status (See Appendix 1). It means that
ethical issue can arise if respondents would have raised the question of why
this personal information is needed and what is the guarantee that this
information will be kept private and confidential. So, a consent form was
signed by all respondents, where they agreed to share their personal
information for this research, and form also included a clause, which stated
that their information is safe and confidential, and it will never be disclosed
without their consent. It is important to understand that for validity and integrity
of research, the ethical issues should always be kept in mind; otherwise,
questions can be raised on moral and ethical grounds.
Results
of Noise Pollution
The above chart shows the age of the
respondents who responded to the survey. It can be seen that the individuals
who are up to the age of 25 are large in numbers who have responded to the
survey questions. The next largest number belong to the respondents who have
ages between 26 to 35 year old.
The survey results show that most of the
respondents agree that Noise pollution really annoys them on a daily basis.
17.65% of the respondents remain neutral whereas 5.88% remains disagreed with
the statement. The results of the survey showed that a significant amount of
respondents remain neutral regarding the effect of noise pollution on mental
health.
Many Respondents agree that vehicles are the
main cause of Noise pollution. The same number of respondents have neutral
views regarding the survey question. In rush hours most of the respondents
experience noise pollution.
Many respondents of the survey agreed that
loudspeaker is a major cause of noise pollution. However, there is a
significant amount of respondents who disagreed with this statement. Mix
responses have been gathered regarding the question of banning loudspeakers
around the world.
Many respondents have a neutral view
regarding stress as noise pollution. However many respondents agree that
loudspeakers cause irritation and disturbance.
Analysis
& Discussion on Noise
Pollution
The
results of the respondents have been mentioned above in the results section,
which revealed the fact that all of the respondents ticked agree and neutral
options for noise pollution as a factor for annoying them, and a factor to
cause mental health issues such as headaches and hypertension. When respondents
were asked about vehicles and traffic as a cause of noise pollution, all of
them agreed that it is one of the major causes of noise pollution. They also
agreed on the fact that most noise pollution happens during rush hours, but when
asked about noise pollution as a cause of stress, few of them agreed, as respondents
remained neutral for this question. Additionally, another cause of pollution
was tried to be analyzed; are the loudspeakers. Majority of respondents believed
that loudspeaker is a major cause of noise pollution; however, there were mixed
responses regarding banning the loudspeakers.
Conclusion
on Noise Pollution
The
research hypotheses claimed that vehicles are considered to be the major cause
of noise pollution as well as various health issues. The results taken from the
survey questionnaire found out that hypotheses were supported by these results
as the majority of survey respondents see vehicles and traffic during rush
hours as the main cause of noise pollution as well as causing health effects
such as headache, stress and hypertension.
