Benefit: Reduced noise level

Reduced noise level has an effect on comfort, well-being and health. The most common health impairments of noise are the feelings of disturbance and annoyance. Chronic exposure to noise impacts on the level of concentration and in children harms cognitive performance.

Continuous noise increases the probability of stress reaction which may expose to many physiological deficiencies such as increased blood pressure and catecholamine hormone secretion, and increased risk of coronary artery disease. Prolonged noise exposure may also disturb the function of the immune system and expose to a variety of infections.

Noise has been studied to decrease the quality of sleep. Lack of sleep may cause, for example, coronary diseases and psychological symptoms. Even if there are no breaks in sleeping there are many physiological consequences of  nightly noise such as increase of blood pressure, heart rate and restlessness.

The level of sensitivity to noise is different for everyone. Some react more intensely to noise and get used to it more slowly. It has been assessed that noise has a negative impact on human psyche causing or aggravating, for example, anxiety and depression.
