Cognitive impairment and Alzheimer’s disease

Prolonged exposure to noise is associated with cognitive impairment and Alzheimer’s disease.

A study in the Chicago area found that each 10 dB(A) increase in residential noise level was associated with a 36% increase in the risk for mild cognitive impairment (MCI) and a 29% increase in the risk for Alzheimer’s disease.

Healthy Life Years Lost

1 million to 1.6 million healthy life years are lost from traffic-related noise every year in western Europe.

(This is a measure of actual life years lost, combined with years lived with disability, which are weighted for diminished quality of life. Also known as DALYs (Disability-Adjusted Life Years).)

Noise is more than a nuisance

It disrupts sleep, increases stress, and contributes to health issues including heart disease, cognitive decline, depression and anxiety. Children, the elderly, women, people with medical conditions, PTSD, and low-income communities are often hit the hardest.

The impact reaches beyond people: Noise disrupts wildlife, stresses pets, lowers property values, and reduces quality of life in neighborhoods. It even adds to healthcare and economic costs on a broader scale.

We believe that informed communities make healthier choices. That is why this site will continue to grow, building a body of evidence-based information covering the full scope of noise’s effects on us all.

The more we understand what noise does to us, the better we can protect our health and our communities.
