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]
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease. [7] [8] In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.

The ocean has become a raucous cacophony as the noise from human activity has grown louder and more prevalent, according to a study. The noisy ocean: Humans have made the world's seas a very loud ...
Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity. The effects in humans of exposure to environmental noise may vary from emotional to physiological and psychological. [2] Noise at low levels is not necessarily harmful.
The report "A Review of Published Research on Low Frequency Noise and its Effects" [54] contains a long list of research about exposure to high-level infrasound among humans and animals. For instance, in 1972, Borredon exposed 42 young men to tones at 7.5 Hz at 130 dB for 50 minutes.
The risk of negative health effects from sound exposures (be it noise or music) is primarily determined by the intensity of the sound , duration of the event, and frequency of that exposure. [9] These three factors characterize the overall sound energy level that reaches a person's ears and can be used to calculate a noise dose.
NASA scientists believe the ominous noises could potentially be the "background noise" of the Earth otherwise known as "Ambient Earth Noise." Since this still lacks scientific confirmation ...
The IPCC (2019) says marine organisms are being affected globally by ocean warming with direct impacts on human communities, fisheries, and food production. [67] 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]
