A study evaluation carried out by the Research Association "Noise & Health" on behalf of the WHO shows that people suffering from sleep disturbances due to noise pollution are significantly more at risk for allergies, cardiovascular diseases, hypertension and migraine. In addition to seeing, hearing is another important sense organ, because hearing is essential for our social interaction.
Hearing in an always loud environment
If you hear badly, you can also communicate badly with others. This limits the ability to socialize and socialize. Isolation and isolation can threaten. The sense of hearing also warns and alarms us when dangers arise.
But: The ear is threatened, because our environment is no longer silent today. Road traffic noise, aircraft noise even the ubiquitous commercial or neighborhood noise echoes our ears. In the meantime, noises are pounding on us almost around the clock - and that can make you sick in the long run.
Noise as a double hazard
There are two risks to be distinguished, namely the damage to the hearing itself and the psychological effects of permanent noise pollution. The facts speak for themselves: tinnitus and deafness have become common diseases. The disturbing thing is that as many as 15 percent of young people already hear as bad as 50-year-olds. Every year, there are 6, 000 new cases of "noise-induced hearing loss" that are recognized as occupational diseases.
The psychological consequences are sometimes even more far-reaching: lack of concentration, cardiovascular diseases, high blood pressure, learning disabilities in children, sleep disorders or psychiatric illnesses to heart attack.
Effect of noise
The pathogenic effect of noise is not as easy to assess as in an infectious disease in which the cause is found and detectable with a pathogen. The health-damaging effect of noise is - apart from hearing damage - usually a long, difficult to understand process, which can be influenced by numerous other factors.
What is noise actually?
We can close our eyes - not our ears. Avoiding noise is therefore not always easy. Noise is an unwanted, unpleasant or harmful sound. Sound as a physical quantity is precisely measurable - noise, however, is a completely individual matter. Here, factors such as sensitivity as well as the inner assessment of what is perceived as noise play a decisive role.
It is also important if the noise is permanent or if it only patters on our ears temporarily. The pain threshold for our ears is 120 decibels, but also street noise with around 80 decibels can make you sick in the long run.
|1 decibel||Hearing threshold - the human being can perceive sounds|
|10 decibels||Rustling leaf|
|60 decibels||Normal noise|
|80 decibels||Busy street, highway|
|85 decibels||The sound waves can weaken the hearing cells and destroy them under constant load.|
|90 decibels||Heavy truck|
|120 decibels||Sound waves are perceived as pain|
|130 decibels||aircraft noise|
Peace and quiet - not easy to find
A consistently high level of noise in the living environment is a risk factor for many physical complaints. However, ongoing noise pollution also has social consequences: noise can lead to sleep disorders, which in turn affect performance at work or at school. Noise on busy roads also disturbs understanding in the family or with the neighbors and restricts the playing possibilities for children. This can lead to isolation and ultimately to a loneliness of the people.
9 strategies for more silence
The German Society for Acoustics (DEGA) gives 9 tips on how to bring more peace into your everyday life:
- Consideration: Do not make more noise than is absolutely necessary and avoidable under given circumstances.
- Protect yourself: Always wear ear protection when required or advised. Use only products with optimal protection.
- Protect your children: Check your children's toys! Crackers and deterrent pistols can cause considerable damage to your hearing even with short-term effects!
- Keep ear protection in place: Before any activity, check whether hearing protection is necessary: for example, when mowing the lawn, cutting the hedge or when doing home improvement.
- Think of your friends: Encourage friends and acquaintances to do the same and reconsider the above points every day.
- Quiet Leisure: Do not engage in recreational activities that are associated with a lot of noise.
- Room volume: Check critically the volume setting on your radio and television sets, which will provide you with daily sound.
- Check-ups: Have your hearing checked by professionals at regular intervals.
- More often Silence: Rethink your habits: Does the CD player, radio or TV have to run in the background? Anyone can take the first step against the annoyance caused by too much noise, namely avoid their own noise. That is, simply turn off the CD player or the TV and let the rest on you. Because: We decide by our behavior and our lifestyle, whether it is quieter around us or not.
