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.
Noise pollution can also affect marine animals. There are many sources of noise in the world's oceans, such as the sounds produced by commercial shipping, sonars and acoustic deterrents. [14] Unnatural noise levels can negatively affect reproductive behaviour, such as courtship behaviours.
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.
Exposure to these substances can result in health effects such as skin irritation, respiratory problems, organ damage, neurological effects, and cancer. [4] Physical hazards are factors within the environment that can harm the body without necessarily touching it. They include a wide range of environmental factors such as noise, vibration ...
The impact of underwater sound can be reduced by limiting the sound exposure received by an animal. The maximum sound exposure level recommended by Southall et al. [54] for cetaceans is 215 dB re 1 μPa 2 s for hearing damage. Maximum sound pressure level for behavioural effects is dependent on context (Southall et al. [54]).
The most recent advances in bioacoustics concern the relationships among the animals and their acoustic environment and the impact of anthropogenic noise. Bioacoustic techniques have recently been proposed as a non-destructive method for estimating biodiversity of an area. [7]
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.
The noise of a jet can cause the frogs to stop or fall out of sync, temporarily breaking this effect and exposing them to other animals. [10] On land, animal communication is shaped by physical characteristics of an environment such as distance, range of vision, weather, and surrounding noise. [11]
