SOUND AND NOISESOUND :- Sound is a sensation of acoustic waves (disturbance/pressure fluctuations setup in a medium)NOISE :- Unpleasant, unwanted, disturbing sound is generally treated as Noise and is a highly subjective feeling.

Measurement of SoundPressure, P, usually Pascal'sFrequency, f, usually HertzIntensity, I, usually W/m2Bels, L, derived from logarithmic ratioDecibels, L, derived from belsP = 1/f

I = W/A

L = log (Q/Qo)L = 10*log (Q/Qo)NOISE POLLUTIONBy definition, noise pollution takes place when there is either excessive amount of noise or an unpleasant sound that causes temporary disruption in the natural balance.Noise pollutionis a serious health hazard and can causeannoyanceandaggression,hypertension, high stress levels,Tinnitus, hearing loss, sleep disturbances, heart disease, mental illness and other serious effects on healthNoise which is above 80dn is specified as polluting noise

INDUSTRIES

INDUSTRIALIZATIONMany industries uses heavy machinery and various equipments like compressors, generators, exhaust fans, grinding mills also participate in producing noise pollutionThey produce noise in the range of 75-85 db of sound.workers in these factories and industries wear ear plugs to minimize the effect of noise.Construction or Isolation of industries from the living area will also prevent people and animals to get effected by the noise pollutionPOORURBANPLANNINGNOISEPOLLUTION

AWAZZ FOUNDATIONSumaira AbdulaliItis anon-governmental organisation in India, which builds awareness, carries out advocacy, and is involved in educational projects toprotect the environmentand preventenvironmental pollution.The Foundation has filed severalpublic interest litigations, including demands for strict implementation ofnoise-pollutionlawsIt was spread across India and also strives for legal issues in sand mafia.

EFFECTS OF NOISE POLLUTION

ANIMALSNOISE POLLUTIONHUMAN BEINGSHEALTH ISSUESSLEEPING DISOREDERCARDIOVASCULAR ISSUESHEARINGTROUBLE COMMUNICATIONBEHAVOUIR PROBLEMSCOMMUNICATION PROBLEMSHEARING LOSSHEARING PROBLEMConstant exposure to noises in the range of 50-75 db can cause this problemMan made noises such as jackhammers, horns, machinery, airplanes and even vehicles can be too loud for our hearing rangeConstant exposure to loud levels of noise can easily result in the damage of our ear drums and loss of hearingIt also reduces our sensitivity to sounds that our ears pick up unconsciously to regulate our bodys rhythm.

HEALTH ISSUESExcessive noise pollution in working areas such as offices, construction sites, bars and even in our homes can influence psychological healthThe occurrence of aggressive behaviour, disturbance of sleep, constant stress, fatigue and hypertension can be linked to excessive noise levels

SLEEPING DISORDERLoud noise can certainly hamper your sleeping pattern and may lead to irritation and uncomfortable situationsWithout a good night sleep, it may lead to problems related to fatigue and your performance may go down in office as well as at home.It is therefore recommended to take a sound sleep to give your body proper rest

CARDIOVASCULAR ISSUESBlood pressure levels, cardio-vascular disease and stress related heart problems are on the riseStudies suggest that high intensity noise causes high blood pressure and increases heart beat rate as it disrupts the normal blood flow. Bringing them to a manageable level depends on our understanding noise pollution and handling it

COMMUNICATIONHigh decibel noise can put trouble and may not allow two people to communicate freely. This may lead to misunderstanding and you may get difficult understanding the other person. Constant sharp noise can give you severe headache and disturb your emotional balance.

EFFECT ON ANIMALSWildlife faces far more problems than humans because noise pollution since they are more dependent on sound They become disoriented more easily and face many behavioural problemsAnimals may suffer from hearing loss, which makes them easy prey and leads to dwindling populations. Others become inefficient at hunting, disturbing the balance of the eco-system. Pets react more aggressively in households where there is constant noiseEFFECT ON ANIMALS (contd..)Species that depend on mating calls to reproduce are often unable to hear these calls due to excessive noise. they are unable to reproduce and cause declining populations. Others require sound waves to echo-locate and find their way when migratingTo cope up with the increasing sound around them, animals are becoming louder, which may further add to the pollution levels

CONCLUSION

Noise that tends to disrupt the natural rhythm of life makes for one solid pollutantThere do not exist many solutions to reduce sound pollution. On a personal level, everybody can help reducing the noise in their homes by lowering the volume of the radio, music system and the TVListening to music without headphones is also a good step forwardRemoval of public loudspeakers is another way in which the pollution can be counteredUsing ear protectors in industries

Controlling the sound levels in clubs, bars, parties and discos.Better urban planning can help in creating No-Noise zones, where honking and industrial noise are not tolerated.
