SOLUTIONS TO NOISE POLLUTION
Unlike Other Injuries, there
is No Visible Evidence of
Noise-Induced Hearing Loss [NIHL]
It is not traumatic or usually even noticed when it occurs.
Hearing impairment accumulates over time
Its effects are realized long after the damage has been done.
Worse, Noise-Induced Hearing Loss is Permanent and Irreversible.
However, with Proper Education and Safety Measures
NIHL is 100% PREVENTABLE
What is noise?
We often hear from people who have returned from
shopping in the market that, there is a lot of noise pollution in the city. They
often blame the two, three - and four wheelers besides commercial units for
increasing ambient noise pollution.
On a special day like festivals, marriage functions, birthday parties etc., we can
hear loud speakers drilling the common man with severe noise pollution.
Let us get familiar with some basic concepts pertaining to noise pollution and its control
Noise can be defined as
“Clamor” “Din” “Loud Outlay”
Noise (Sound) is a physical disturbance
that is capable of being detected by human ear.
It is due to any manmade Industrial Activity, Commercial Industrial
Activity, Domestic Activity or Natural Activity.
Depending upon the noise levels and duration of exposures,
various impacts on human beings can be enumerated.
NOISE
is an Unwanted Sound
A Noise Problem generally consists of THREE
inter-related elements-
The Source
The Transmission Path
The Receiver
The discrimination and differentiation between
sound and noise depends upon the habit and
interest of the person/species receiving it and the
ambient conditions and impact of the sound generated
during that particular duration of time.
Noise may be:
Continuous or Intermittent
Noise may be:
High Frequency or Low Frequency
EFFECTS OF NOISE POLLUTION

Annoyance, Tensions in Muscles, Nervous Irritability & Strain
PERSONOLOGICAL EFFECTS
Disturbance in Individual‘s Total Personality Make-up, Insomnia,
Fatigue, Hypertension, Blood Pressure, Deafness
Have you observed ??
Any change in your personal reactions like
annoyance, tiredness, loss of concentration while
executing your daily activities?
Any noise polluting source in your surroundings?
If so, for how much time, you are exposed to the noise levels?
Any noise level measurements being taken at your surroundings?
Air borne Noise Levels have been limited in different areas
as per notification dated 26th" December-1989 under schedule-III
by Ministry of Environment & Forests (MOEF) Govt. of India

(*dB(A) Leq denotes the time weighted average of the
level of sound in decibels on scale A which is relatable to
human hearing.
A "decibel" is a unit in which noise is measured. "A", in
dB(A) Leq, denotes the frequency weighting in the
measurement of noise and corresponds to frequency
response characteristics of the human ear. Leq : It is an
energy mean of the noise level, over a specified period.)
International & National
Legislations
Noise limit levels vary from country
to country.
The ILO code of practice indicates that in
the light of present knowledge, the following
values may be recommended :
Warning Limit Value :
85dB
Danger Limit Value :
95dB
Further it adds that No matter for how short a
time, a worker should not enter an area where
the noise level is 115dB or more without
Appropriate Ear Protection.

Legislation On Noise In India
Constitution of India : Right to Life
Environment Protection Act
Noise Pollution Control Rule 2000
under
Environment Protection Act 1996
INDUSTRIAL NOISE
Industrial Noise is largely produced by the
industrial machines. The survey recently conducted
by the Oto – Rhino - Laryngology, Madras, revealed that
Industrial Noise Pollution has damaged the hearing ability of
nearly 20% workers.
The major noise sources are flow of oil, water and gas through pipes, valves etc.
The noise level close to valves is in between 80 - 90 dBA.
The noise level close 40 mts. from the flare is around 70 dBA.
The general noise level ranges between 70 – 90 dBA
CONTROL TECHNOLGIES AVAILABLE
FOR NOISE POLLUTION
To Isolate NOISE At Source:
# The first and simple way to control the noise pollution is insulation
# Department for the Maintenance should have a routine checkup to observe
the noise generated by every machine of the plant and restrict to its original
noise level by replacing bearings, tightening of all loose parts that can
vibrate.
# Machines should be placed on vibration isolators or mounts.
NOISE Control in Path :
In many cases, noise control at source is very difficult or quite
uneconomic. In such cases, noise control is achieved in the path:
(a)
(b)
(c)
(d)
Putting major noise sources at one place & separating it from quieter area.
Using acoustic barriers, sound absorbing linings & sound insulating partitions.
Complete or partial enclosure of noisy equipment.
Providing silencers on the intake as well as exhaust side of flow machines, like,
blowers, fans etc.
(e) Insertion of damping material between machine bases and foundations and use
of anti vibration mountings.
(f) Damping vibration of the crucial parts through the use of the correct fabrication
material.
Noise Control at the Receiver End :
Wherever it is not possible to reduce noise exposure
to the permissible limit at the source or in the path,
the workers exposed to high sounds should be provided
with suitable Ear Protector.
Receivers can protect himself by:
Making use of # Acoustically Closed Cabin # Ear muffs, # Disposable Ear Plugs
Or,
CUSTOM MADE
HEARING PROTECTION DEVICES
Conclusion:We have made the laws relating to noise pollution but
there is need of
effects of
Creating General Awareness towards the hazardous
Noise Pollution.
In our country the people generally lack consciousness of the ill effects which noise
pollution creates and how the society including they themselves stand to beneficiary
preventing generation and emission of noise pollution.

Advantages of Custom Made
Hearing Protection?
Comfort
One of the problems that many people may face with disposable
ear plugs is comfort. As they are a universal size, they can sometimes
be too small or too big or don’t sit in the ears correctly. Because custom hearing protection is
made from your own ears, you can be assured of the most comfortable fit.
Sealing of the Ear Canal
Foam ear plugs are Non – Hygienic as they are being used regularly and cannot be washed. For
hearing protection to work effectively, an air-tight seal is required between the hearing protection
and the ear canal. As custom protection is made from the shape of your own canals, a secure fit is
ensured, providing much more effective protection against noise damage than the disposable type.
Advantages of
Custom Made Swim Plugs ?
To prevent water from entering the ear canal, an Airtight
Seal is required between the ear plug and the ear canal.
A Good Fit is essential to ensure that water doesn’t leak into the canal.
As custom swim plugs are made from the shape of your ears, a secure fit is ensured,
providing the most effective protection against water entry.
