We are surrounded by noise. The discussion of our colleague, traffic noise, noise from high heels hitting the floor, the music of headphones a passenger in the bus, it's so much noise, so much noise and the worst is that they often do not realize that our everyday environment is surrounded by all this.
But in reality, what many do not suspect is that the distant sound of the jackhammer, the police siren and even the whistle and the ringing of the people around us can have a real effect on our health and the secret will always prevention: avoid noise as much as possible.
Arline Bronzaft, environmental psychologist at New York University and a pioneer in research on noise, explains the impact of noise in our perception: "While the ears recovered the sound vibrations and send them to the temporal lobe for interpretation, are the cognitive functions of the brain that determines whether the sound is undesirable, unpleasant or disturbing. "
The different ways that noise can affect your well-being
The noise can affect learning ability
In a study that refers to sounds and learning , researchers followed two classes at an elementary school in Inwood - a suburb of New York served by an air train. Children in classrooms that are just to the side of the tracks shown to have almost a year of delay learning in relation to children studying in classrooms that were not near the tracks - such rooms are in the "quiet" part of the school.
How come? It's simple: according Bronzaft who led the research, the noise was disturbing enough for teachers to teach 11% less time in rooms noisy classroom.
The noise makes people less productive at work
In a recent article that talks about the offices open, Maria Konnikova the New Yorker revealed that 70% of offices are made in open spaces, or are those offices that have only small partitions of about five feet and sometimes not it, but never actually have walls. This major trend of architecture creates an environment with many disadvantages, including the spread of diseases, lack of personal space, and of course, a big noise in the environment that affect productivity.
The researchers found that background noise very characteristic of offices offices in shared space inhibits the ability of employees to retain information and perform basic tasks, such as arithmetic, for example. How come? More than a simple distraction, the sounds of an open space cause stress.
During a study done in the laboratory with women who worked with a certain level of noise in an open space and a second group working in a quiet environment and without noise, the researchers found that women in the first group have higher levels of adrenaline in the blood,
also indicating an abnormal level of anxiety . Next, the researchers asked participants to solve a series of puzzles unsolved. The participants of the first group (who were more stressed) made fewer attempts to assemble the puzzle, showing a reduced motivation.
A noisy environment can be fatal
According to a 2011 report of the Joint Research Centre of the WHO and the European Commission, regular exposure to a noisy environment, especially if it includes transport noise as the landing of an aircraft or the noise of a train passing on the tracks may lead to an increase in blood pressure and an increased risk of heart attacks fatal.
