The chirruping songs of birds and bees may no longer
greet you in the mornings. Rather eching
brakes and noisy horns a-e probably assailing your eardrums. Vehicles that give
off harmful emissions, rule the roads polluting the air near your dwelling
place. You may be seated in your comfortable hying room yet the level of noise
could make you think your room is actually a busy road. As commercial zones
have now come up in residential areas, busy traffic characterizes the hitherto
quiet roads. It remains to be seen how this factor ofnoise pollution can be
dealt with.
If windows that face busy roads are always kept closed
it is necessary to consider the different types of insulation to use.
Rubber felts and gaskets usually are fitted around the
glass in the window. A good beading such as that of a car will keep out noise
as well as the vibrations. If a window is not properly fitted, the noise and
vibration of moving vehicles is sensed inside. Should your patio overlook a
busy street there is not much point having French windows opening on to it. It
would be wiser to have artificial ventilation as fresh air cannot be obtained
here.
According to an architect, EPDM gaskets fit snugly and
are light and thin. The usual rubber gaskets have the disadvantage of being
heavy and become hard losing their elasticity and cracking in a single summer.
Polymer is a material with zero sound and vibration
being the best choice. However as it is costly, it is not very popular. You can
have either wooden, aluminium, steel or polymer frames for the windows. The
most sought after material lately is aluminium. If aluminium is of good quality
it will shut out the noise some what. The lower quality one that is not machine
made may be unsuitable for fitting and could have gaps through which noise may
seep in. If sliding windows with aluminium frames are used they may leave gaps
when it is not well structured. No gasket will be effective in that case.
You may have either sliding or casement type of
windows. Casement windows fit better and shut out most of the noise and
vibration. Its insulation too is effective.
Recently double glasses with a thin laminating film
have become available that shut out the noise totally. It is possible to obtain
these laminated double glasses off the shelf in regular sizes but the fitting
is important. In case of a bad fitting the purpose may be defeated completely.
The effectiveness of the insulation depends largely on
the type of window frame and beading used but in order to have effective
insulation one must go for double glass window glazing. In this the gap between
two pieces of glass is filled with a vacuum which stops noise traveling from
the outer layer to the inner one. If there is air in the gap the noise will
travel through the medium making double glass useless.
Rough surface exterior walls are important if the house
faces a glass building. As glass reflects sound it will be increased in a noisy
area. The exterior walls should be rough to remove the noise.
It is best to choose heavy curtains, upholstered
furniture, carpets, wall paper and textured paints to diffuse the noise. Cloth
absorbs noise and rough surfaces diffuse it. One could plant trees, and hedges
along the road to absorb the noise.
