Noise pollution is the disturbing or excessive noise
that may harm the balance and activity of human
or animal life.
The most common sources of outdoor noise, also
called environmental noise, worldwide are caused
by machines and transportation systems, such as
road traffic, planes, jet skis, garbage trucks,
construction equipment, manufacturing processes
and boom boxes, to name a few, are among the
audible litter that are routinely broadcast into the
air.
Any type of noise, harmful or not, can be
felt in slight changes in preassure, measured
in decibels(abbreviated dB) which measure
the intensity of a sound, in a scale of 0-150.
Any sound above 85 dB can cause hearing
loss; you know that you are listening to an
85-dB sound if you have to raise your voice
to be heard by somebody else.

dB: Hearing threshold
 20 dB: Leaves fluttering
 30 dB: Whisper in the ear
 60 dB: Normal speech conversation for a
participant
 60-100 dB: Motor vehicles for a close observer
 120 dB: Airplane taking off for a close observer
 120-140 dB: Pain threshold

Permanent hearing loss can be caused by a onetime exposure to an intense “impulse” sound, such
as an explosion, or by continuous exposure to loud
noises over an extended period of time.
Long or repeated exposure to sounds at or above
85 decibels can cause hearing loss. Sounds of less
than 75 decibels, even after long exposure, are
unlikely to cause hearing loss.
Most problems caused by noise pollution are stress
related illnesses, speech interference, hearing loss,
sleep disruption and lost productivity.
Still, there are two major effects we must also look
at:
 Hearing  The effect of noise pollution to a
person is damage to the eardrum, which
may result in a permanent hearing.
 General Health The physiological manifestations
are anxiety and stress reaction, alongside with
headaches, irritability and nervousness, feeling of
fatigue and decreases work efficiency. It can also
cause hair cell damage, fiber loss,
communication, interference, cardiovascular
disturbances and hysteria.

 Construction
of soundproof rooms for noisy
machines in industrial and manufacturing
installations must be encouraged.
 Use
of horns with jarring sounds, motorbikes with
damaged exhaust pipes, noisy trucks to be
banned.
 Noise
producing industries, airports, bus and

Community law enforcers should check the
misuse of loudspeakers, worshipers, outdoor
parties and discos, as well as public
announcements systems.

Community laws must silence zones near
schools / colleges, hospitals etc.
Vegetation (trees) along roads and in
residential areas is a good way to reduce
noise pollution as they absorb sound.

Noise pollution affects the environment in Cartagena
because the caribbean culture is characterized for it´s
tendency to use big stereos with large volume quality,
also called “pikos”, which tend to distrurb the peace of
the people in our city by constantly playing different
music genres such as vallenato, salsa, champeta,
merengue, etc in public places.
This constant exposure causes health problems to
surrounding residents which are made mainly to older
adults or people with disabilities ; It can also become a
a nuisance fr those who are not involved in this kind of
activity, because they can not sleep and usually in this
kind of celebrations are fights that cause damage to
homes in the vicinity.
Another issue concerning noise pollution in Cartagena is
the fact that our local airport (Aeropuerto Rafael Nuñez) is
located within the city parameters without providing any
kind of noise barrier, such as walls or soundproof fences.
This directly affects the residents of Crespo, Marbella and
other vicinities nearby because it works 24/7 so nearby
neighbors are exposed to constant noise between 120-140
dB during most of day and night which can lead to
complete hearing loss and concentration difficulty at a
young age.
And while some might think that implementing noise
barriers after so long of the airport being there is not a
priority, we as citizens have to encourage the mayoralty to
fulfill this requirement so our fellow neighbors of Crespo
and Marbella can have better life quality.
The prove that this is posible is that the construction of a
wall with certain technical specifications and specific
materials as an alternative vented by the Regional Port
Society of Cartagena (SPRC), to mitigate noise problems
generated by its operations permanently and directly
affecting residents of sector Las Colonias in Manga.

Have large size banners or boards with no horn or
limited horn symbols
Educate students, employees, drivers of all vehicles
about the noise pollution in masses.
Start off huge rallies against noise pollution
Have sound detectors near offices, hospitals,
educational institutions and residential areas.
Punish those who violate this rule by imposing fine.
Keep factories far from cities areas.
Don't blast music on the radio or computer or
speakers. Be considerate of your own ears and those
of other around you.
Train your dog not to bark so much.
Sound is a kind of vibration which travel through air,
water, and are sensed by the ear. This is from
music, speech, and others like films dialogs etc.
One thing in this matter is that we can increase the
volume of sound or decrease as per our taste if it is
from radio, television, computers and man
operative machines.
Whereas a noise is a sound from one and more at
a time which can not be heard clearly and only
mixed sounds will be heard. As a fact you can not
increase or decrease the noise.
