   INTRODUCTION
   CAUSES
   EFFECTS
   SOLUTIONS
   CONCLUSION
   Noise pollution is excessive, displeasing human,
    animal or machine-created environmental noise
    that disrupts the activity or balance of human or
    animal life. The word noise comes from the Latin
    word nauseas, meaning seasickness.
   The source of most outdoor noise worldwide is
    mainly construction and transportation systems,
    including motor vehicle noise, aircraft noise and
    rail noise.[1][2] Poor urban planning may give rise
    to noise pollution, since side-by-side industrial and
    residential buildings can result in noise pollution
    in the residential area
   Noise health effects are both health and behavioral
    in nature. The unwanted sound is called noise.
   This unwanted sound can damage physiological
    and psychological health. Noise pollution can
    cause annoyance and aggression, hypertension,
    high stress levels, tinnitus, hearing loss, sleep
    disturbances, and other harmful effects.
    Furthermore, stress and hypertension are the
    leading causes to health problems, whereas
    tinnitus can lead to forgetfulness, severe
    depression and at times panic attacks

    disturbances, and other harmful effects.[3][4][5][6]

    leading causes to health problems, whereas
    tinnitus can lead to forgetfulness, severe
    depression and at times panic attacks
   The noise pollution can be controlled at the source of generation itself by employing
   techniques like-
   · Reducing the noise levels from domestic sectors: The domestic noise coming
   from radio, tape recorders, television sets, mixers, washing machines, cooking
   operations can be minimized by their selective and judicious operation. By usage of
   carpets or any absorbing material, the noise generated from felling of items in house
   can be minimized.
   · Maintenance of automobiles: Regular servicing and tuning of vehicles will reduce the
   noise levels. Fixing of silencers to automobiles, two wheelers etc., will reduce the noise
   levels.
   · Control over vibrations: The vibrations of materials may be controlled using proper
   foundations, rubber padding etc. to reduce the noise levels caused by vibrations.
   · Low voice speaking: Speaking at low voices enough for communication reduces the
   excess noise levels.
    Proper lubrication and maintenance of machines,
   vehicles etc. will reduce noise levels. For example,
    it is a common experience that,
   many parts of a vehicle will become loose while on
    a rugged path of journey. If these
   loose parts are not properly fitted, they will
    generate noise and cause annoyance to
   the driver/passenger. Similarly is the case of
    machines. Proper handling and regular
   maintenance is essential not only for noise control
    but also to improve the life of
   machine.
