“The ear is on reception day and night, making it one of the most vulnerable human organs.”

Sickness noise

International studies confirm that noise causes long term serious illness. Although residents seem to “get used to” noise from busy streets and railways, the human ear transmits the information recieved at any time of the day or night to the brain.

Even with events of more than 55 dB(A) during the day and more then 45 dB(A) at night , the risk of physical stress reactions increases in the long run many times, such as high blood pressure, heart attack, stroke, migraine, intestinal diseases and tinnitus.
