anthropogenic noise

"Noise pollution refers to the elevation of natural ambient noise levels due to sound-generating human activities, which may have detrimental consequences for humans and animals alike. Sounds of this kind are often referred to as anthropogenic noise. Some of these sounds are deliberate and wanted, such as music, sirens, seismic survey sounds or military sonar. Most anthropogenic noise, however, is an unwanted by-product, such as traffic or generator noise, and impulsive sounds from pile driving and explosives." [1]
