Society today is noisier that ever.

Modern world is full of different, various noises. Motors, aircraft, railway stations, animals, displeasing human, music playing in bar. Anything can create it. Nowadays people practically do not hear silence at all, that is the problem because noise pollution affects both humans heath and behavior.
Furthermore unexpected sounds can damage psychological health and hearing abilities, to cause annoyance and aggression. To compare with previous generations, which did not catch these crazy amount of technologies we are much more subjected to depression, we are much more aggressive and offensive, noise influences blood pressure, it increases making us act like that. 

I could say that government should make something to reduce this amount of noise pollution, but everyone knows that government has a lot of other different things to take care of. Curfews are in the past, no one would listen and obey these kind of rule or law, because today's people are much less disciplined.
In my opinion the problem is in us. We do not respect each other shouting and speaking loudly wherever we want. We can not declare of those benefits that our technological world gives, but respect each other is in our power. If people were more well-wishing towards each other, there would not happen neighbors problems and any others too. If we save our world from arguments, I am sure that we will make it much more quieter.
