Social factors of noise pollution :-

(i) Industrial Sources:- Progress in technology (industrialization) has resulted in creating noise pollu­tion. Textile mills, printing presses, engineering establishments and metal works etc. contribute heavily towards noise pollution.

(ii) Transport Vehicles:- Automobile revolution in urban centers has proved to be a big source of noise pollution. Increasing traffic has given rise to traffic jams in congested areas where the repeated hooting of horns by impatient drivers pierce the ears of all road users. Heavy trucks, buses trains, jet-planes, motor-cycles, scooters, mopeds, jeeps—the list of vehicles cause noise pollution.

(iii) Public Address System: - In India people need only the slightest of an excuse for using loud speakers. The reason may be a religious function, birth, death, marriage, elections, dem­onstration, or just commercial advertising. Public system, therefore, contrib­utes in its own way towards noise pollution.

(iv) Agricultural Machines:-  Tractors, thrashers, harvesters, tube wells, powered tillers etc. have all made agriculture highly mechanical but at the same time highly noisy. Noise level 90 dB to 98 dB due to running of farm machines have been recorded in the state of Punjab.

(v) Miscellaneous Sources: - The automobile repair shops, construction-works, blasting, bulldozing, stone crushing etc. are other sources of noise pollution.
