Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.
A meta-analysis published in 2019, found that the risk for depression increased by 15 percent per 10 decibels of noise for aircraft noise and 4 percent per 10 decibels for road traffic noise.
The negative effects of anthropogenic noise impact a wide variety of taxa including fish, amphibians, birds, and mammals. [26] In addition to interfering with ecologically important sounds, anthropophony can also directly affect the biological systems of organisms.
Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels. Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. [2]
It was pretty horrific – I wasn’t able to sleep because of this noise drilling into my head the whole time.” He says he gave up on everything. “I used to be the life and soul of the party ...
Sound is the sensory cue that travels the farthest through the ocean, and anthropogenic noise pollution disrupts organisms' ability to utilize sound. This creates stress for the organisms that can affect their overall health, disrupting their behavior, physiology, and reproduction, and even causing mortality. [42]
The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. [20]
However, chemical pollutants are not the only anthropogenic offenders. Noise and light pollution also induce abnormal behaviour. This topic is of special concern for its conservation and human health implications and has been studied greatly by animal behaviourists, environmental toxicologists, and conservation scientists.
