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.
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.
Noise refers to sound which is unwanted, either because of its effects on humans and wildlife, or its interference with the perception or detection of other sounds. Cultural soundscapes include opportunities for appropriate transmission of cultural and historic sounds that are fundamental components of the purposes and values for which the ...
The historical background of natural sounds as they have come to be defined, begins with the recording of a single bird, by Ludwig Koch, as early as 1889.Koch's efforts in the late 19th and early 20th centuries set the stage for the universal audio capture model of single-species—primarily birds at the outset—that subsumed all others during the first half of the 20th century and well into ...
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 ]
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.
Listening is still one of the main methods used in bioacoustical research. Little is known about neurophysiological processes that play a role in production, detection and interpretation of sounds in animals, so animal behaviour and the signals themselves are used for gaining insight into these processes.
