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.
However, current knowledge indicates that they are likely affected by anthropogenic noise to a greater extent than many other animal groups. [ 38 ] [ 39 ] Insects, like birds, rely heavily on acoustic signals for communication, which can be disrupted by noise.
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 is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change. [ 68 ] A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse ...
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.
Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities. [1] Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity.
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 ...
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.
