Impact of Individual Anomalous Noise Events on the Monitoring of Traffic Noise in Urban Areas

At least one million healthy life years are lost every year from traffic-related noise in the western part of Europe according to the World Health Organization. Other diseases have been linked with environmental noise, such as sleep disturbance, heart illnesses or tinnitus. The Environmental Noise D...
