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.

A spectrogram of the soundscape of Mount Rainier National Park in the United States. Highlighted areas show marmot, bird, insect and aircraft noises. Soundscape ecology is the study of the acoustic relationships between living organisms, human and other, and their environment, whether the organisms are marine or terrestrial.
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.
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 highest levels of stress were reported after the fastest traffic sounds. Ultimately, the researchers concluded that reducing speeds in urban areas could enhance human health and wellness.
“One purpose of my project is separating anthropogenic sounds from the Hum,” he says. “For example, the mains electric hum, mining, heat pumps, marine traffic, and so on, can often present ...
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.
Human changes in the habitat modify acoustic environments and may make it more difficult for animals to communicate. Humans may alter acoustic environments by modifying background noise levels, modifying habitat, or changing species composition. [5] These changes in acoustic environments can mask the vocalizations of various species.
