Method of Research : Survey Question
For my project. I have provide some question which is survey questionnaire to the public mostly in urban areas. For this survey I focusing on three places which is
This is an example of survey question that I had done.
- Bukit Bintang
- Bangsar
- Along Federal highway
This is an example of survey question that I had done.
- What are the causes of noise pollution?
- What are the effects of noise pollution on people's health, in general?
- What are the effects of noise pollution on the children's health?
- What are the effects of noise pollution on the environment?
- How can we reduce the noise pollution?
- What are the precautions we can take to avoid noise pollution?
The effect from the noise pollution
The effects
Noise
has direct physiological effects to human such as hearing damage which can be including
hearing loss and tinnitus, or ringing in the ears, as well as cardiovascular and hormonal disturbances.
Indirect effects include sleep loss, interference with concentration and
learning, mood changes and aggression, and social isolation.
Noise
pollution is also becoming huge problem for many animals. Their hearing for
detecting predators, finding mates, establishing territory, and recognizing
warning alerts. Unnaturally high levels of noise can damage their hearing and
can also mask more subtle sounds that they need to hear in order to survive and
reproduce. They may also react with a fight-or-flight response to artificial
sounds such as aircraft noise, thereby using up valuable energy reserves to
flee from a non-existent predator. If noise in urban area becomes too
intrusive, animals may shift to a new territory or alter their migration
patterns, which can create new complications for their mating and survival.
Noise
Pollution effects the environment. As we all known that plants are similar to
human being. They are also as sensitive as man. There should be cool and
peaceful environment for their better growth. Noise pollution causes poor
quality of crops in a pleasant atmosphere.

The Chosen Topic :Noise Pollution in urban city
Definition
of noise pollution
The definition of noise pollution is can be elaborate as a type
of energy pollution in which distracting,irritating, or damaging sounds are
freely audible. Noise pollution contaminants are not physical particles, but
rather waves that interfere with naturally-occurring waves of a similar type in
the same environment. Sounds are considered noise pollution if they adversely
affect wildlife, human activity, or are capable of damaging physical structures
on a regular, repeating basis. In the broadest sense of the term, a sound may
be considered noise pollution if it disturbs any natural process or causes
human harm, even if the sound does not occur on a regular basis.

be considered noise pollution if it disturbs any natural process or causes
human harm, even if the sound does not occur on a regular basis.
Measurement for sound
Sound is
transmitted in series through
the air with the wave compressed. When
it comes to sound, there are three terms that can connected
with it, the strength, pitch or frequency.
Strength calculated in units of decibels (dB).
Decibel is a ratio
expressed on a logarithmic scale. This logarithmic scale takes care of wide
range of sound power, intensity and pressure. The decibel (dB) scale begins
from zero, which represents the faintest sound, which is audible to a normal
ear. Decibel (dB) is used in environmental noise pollution as a measure of
sound power level, sound intensity level and sound pressure level. A decibel is
a physical unit based on the weakest sound that can be detected by the human
ear. It is named after Alexander Graham Bell, the inventor of the telephone.
Our human ear sensitivity to noise in
the range of 20 to 20,000.
Sources of noise pollution
People
living in urban city complained about
the noise from automobile traffic, overhead airplanes and helicopters, leaf
blowers, pneumatic drills, and neighbors who play their televisions and stereos
much too loudly. Large urban areas are being inundated by unwanted sounds.
These sounds or noises are disturbing, disrupting ongoing activities and
peaceful interludes. One cannot concentrate on a work project if there is
constant drilling at a nearby construction site. It is virtually impossible to
enjoy a television program when overhead jets frequently drown out its sound.
It is difficult to fall asleep if your upstairs neighbor's stereo system is
blasting away.
There are many sources of noise pollution that created in urban areas.
The sources in general may be stationary or mobile. The example of stationary
sources is such as when use of loudspeakers on various occasions like
festivals, elections, worships in temples, mosques and during advertisements,
mining operations, use of bulldozers, drillers and dynamites to break rocks,
household gadgets like vacuum cleaner, TV, radio, stereo, grinder, mixer. In
the other hand, mobile sources can be classified in Transportation / Traffic
noise (Road
Traffic or Highway Noise), Industrial noise, Noise from
construction work and also Neighborhood noise.

Proposal 3 : Lack of wearing traditional cloth (the younger generation) in urban city
Background Research
Traditional clothes can still be seen worn especially at official functions,However, in daily activity, wearing traditional clothes among teenagers appear to have declined since been replaced by wearing T-shirts and jeans that was allegedly more simple and comfortable.Young people prefer a simple dress shirt than traditional especially in large urban areas, this is because many felt that the working conditions that require rapid movement makes them choose to wear shirts and pants for easy moving from a traditional dress that restrict some movement.
-------------------------------------------------------------------------------------------------
Problem Identification
Problem Identification
- Leak of knowledge about traditional cloth.
- Most of this generation think that urban wear is more suitable for them.
Aim and Objective
- to give some information to the young generation about traditional cloth.
- to show that wearing traditional cloth is represent the culture and identity of person.
Idealization and Concept
- idea 1 - making the interactive application & website that user can get the infromation
- idea 2- creating video and project the video (mapping) to some creative object/thing.

Proposal 2 : Noise Pollution in Urban
Background Research
An important factor for the life quality in urban centers is related to the noise levels to which the population is submitted. Several factors interfere with the amount of noise pollution throughout the city. Among them, and as one of the most important, is the traffic noise.Noise pollution is a serious problem because it can disrupt the health of the population.
Some of example of noise pollution in the city :
- Noise Pollution due to vehicles, such as the LRT and Commuter especially in Kuala Lumpur.
- Factories, which operates mainly in crowded urban areas, pose a serious problem of noise.
- The noise generated from highway traffic is one of the major sources of noise pollution.
- Aircraft noise differs from road traffic noise in the sense that it is not continuous but intermittent.
- Noise from construction sites is generally far worse than the noise originating from factories
- Neighborhood Noise-It includes a variety of noise sources which disturb and annoy general public especially during festival
-------------------------------------------------------------------------------------------------
Problem Identification
Problem Identification
- To awareness the sound pollution to people that lives in urban area
- How noisy the sound in everyday life in urban city
Aim and Objective
- to alert people that noise pollution can be dangerous to health
Idealization and Concept
- By using sound mixer ,user can play around and mix the sound(ambient sound of pollution) in one time.
- Visual will appear according to the ambient sound chosen.
