Exkurs: "Why can latin aremicans not live without noise?" or "Are all the people deaf here?"

Imagine a world were you hear loud music all night through because they run music in the streets and in the neighbourhood all night long and your windows and walls are made of paper... a world were all people shout, no matter where they are and what time it is...
...where the hotel personal vacuums the floor in front of your room at 6:00 a.m.,
...where the TV runs in all restaurants, in all bars and cafes, in the buses, in waiting halls, in post and bank officies..and at all times with high volume,
...where in each taxi and bus the radio runs at highest volume level additionally to frequent horning,
...where at 7:00 a.m. the nearby schools decide to take their lessons or morning songs with a microphone so that everybody living within 500m can participate,
...where the local bands decide to play all day long marches in all the street of downtown at the same time,
...where whole downtown consists of music clubs and the word "acoustic insulation" is unheard of ...
Welcome to the world of South America and the world we have been living in for the last 6 months .... AAAAAAAhhhhhhh!!!!
So don't expect me to react if you talk to me at normal volume at home again as I sure should be half deaf by now :-)

The reason for this behaviour has not revealed itself to me till until now, although I can honestly say that we did extensive investigations on this (although most of the time involuntarily). I really wanted to understand the basics of this logic and even at times tried to imitate them...but the question remains unsolved....

Renate, who did not have had a good sleep for at least two weeks in a row....
