Li-Fi abbreviated as Light Fidelity emphasizes on the idea of
transmission of any images or audio/video signals with the help of visible
light. Using this very concept, in the past few years, various
application-oriented industrial sectors have evolved tremendously or are on the
verge of evolving. One such domain that has taken into consideration the
concept of Li-Fi and put it into practice is vehicle communication. Li-Fi has
successfully made its way in smart vehicle communication resolving problems like
road accident, traffic control among many. Working on the same domain as
vehicle communication, we intend to address another rigorous problem associated
with vehicles that has a huge impact on human lives, that is, noise pollution.
Horns built inside every car, when honked, creates excess noise and leads to
cacophonous environment. Thus, adhering to the ideology of Li-Fi, we, in this
project, make an effort to replace the harsh honking with a simple sound signal
that will travel through LED based headlights, that is to say, sound signal
will be superimposed on light signal. At the receiver section, a solar panel,
speaker and an amplifier is used to obtain the amplified version of original
input sound signal. The two incredible properties of Li-Fi due to which the
entire proposed system becomes reliable are, one, Li-Fi uses visible light as a
source whose availability is in abundance and is harmless and another, the
signals received remain confined within the system itself.
