Whether noisy should be controlled strictly or not ? Noisy pollution has increasingly been to one of hottest topics in recent year, but there are still some people arguing about strictly limit noisies. And I think noisy is hard to define as the same principle for individuals. So I think the most priority thing is to control something having been defined and really noise. Human is inevertable to make a few noises, which may includes source of creativity. If we limit any possible noisy, resulting in limiting the developing of arts. For instant, music is one of the art field by making sounds. when pianist novices are practicing their piano enthusastically, they can be limit to make any noisy by rigor laws. The next Mozart may disappeared, thereby we should make sounds free as we want. However, nosiy really bother us in some extent. Sometimes we have to limit some noisy shouldn't appear. For example, when we make a classic Mozart music concert, we must be angry with someone who sing some rock music suddenly. At this time we really want some convention and principle to limit people's behaviours to keep a quiet place to relax ourselves. In my opinion, we should more focus on where the noises are made instead of controlling any noises bothering us and making noises as we want. That's why we do not want some ridiculous people make any noise during watching beautiful movies but we all make noisies when we play in night clubs. In conclusion, noisy is hard to define but where the noisy is made is the priority thing.
