Sound environment
Few weeks ago I've heard a podcast episode, which said a few interesting facts about hearing and sound environment.
First of all I've remembered, that in some city in USA street crime was decreased using following method. They just placed speakers on the trees in the public areas. Through these speakers birds signing was translated. It's hard to belive, but this led to decrease of street crime by 20%! The reason is that people (regarded as spice) used to be in the wild nature, which have its natural sounds. Eliminating this sound background make person worry and led to frustration.
Other interesting fact that I've learned from this episode, that ordinary piping of frogs - it is well ruled perfomance, which is synchronised in a certain way. This helps them notice removing any of member this chorus. It's accurately designed security system. Furthermore, it works not only for frogs nut for all inhabitants of pool. Finally sad fact could be mentioned - passed plane destroy this synchronisation, recovering takes about half an hour.
All this mean, that humanity has to be more carefull about environment, and considers not only about chemical pollution and global warming, but also about sound pollution.

Sound environment
A few weeks ago I heard a podcast episode, which gave a few interesting facts about natural sounds in our environment.
First of all in some cities in the USA street crime was decreased using following method. They just placed speakers on the trees in public areas. Through these speakers birds signing was played. It's hard to belive, but this led to a decrease in street crime by 20%! The reason is that people used to be surrounded by nature, which has natural calming sounds. Eliminating these background sounds makes a person worry and this leads to frustration.
Another interesting fact that I learned from this episode, is that the croaking of frogs is a well co-ordinated perfomance, which is synchronised in a specific way. This helps them notice missing members of their choir. It's an accurately designed security system. Furthermore, it works not only for frogs but for many inhabitants of ponds. Finally major setback should be mentioned - passing planes destroy this synchronisation, recovery takes about half an hour.
All this mean, that humanity has to be more carefull about the environment we live in, and consider not only chemical pollution and global warming, but also about noise pollution.
