The building site next door, the aeroplanes in the flight path, the traffic noise from the main road - there are many sources of noise. If the noise exceeds around 90 decibels, there is a risk of sudden hearing loss. From 100 decibels at the latest, ear protection should be used to protect employees' hearing. However, very few offices are permanently exposed to these extreme noise sources. Noise protection in the workplace is much more about keeping medium noise levels out of the office. This is because the risk of chronic illness increases significantly if these levels persist throughout the working day:
Cardiovascular
Prolonged noise causes high blood pressure and an increased heart rate. Over months or years, this can lead to heart attacks, arteriosclerosis and other cardiovascular diseases.
Stress
A restless environment triggers stress hormones that make you lose concentration in the short term. Over longer periods of time, the risk of illness increases.
