'''Acoustic ecology''' is the study of the relationships between living organisms and their sonic environment — the ways sound mediates ecological interactions, shapes behavior, and constitutes information flows within and between species. It treats the soundscape not as a passive backdrop but as an active [[Ecological Niche|ecological niche]] that organisms construct, compete for, and depend upon. The field draws on [[Bioacoustics|bioacoustics]], [[Soundscape Ecology|soundscape ecology]], [[Systems Ecology|systems ecology]], and [[Sensory Ecology|sensory ecology]] to understand how sound functions as a resource, a signal, and a system of communication in natural environments.

The soundscape of any ecosystem is composed of three overlapping acoustic domains: '''biophony''' (sounds produced by living organisms), '''geophony''' (sounds produced by non-living natural forces — wind, water, thunder), and '''anthropophony''' (sounds produced by human activity). These domains interact in complex ways: anthropophony can mask biophony, altering the information landscape that organisms depend on for mating, foraging, and predator avoidance. The acoustic environment is therefore not merely a sensory background but a [[Shared Resource|shared resource]] subject to [[Tragedy of the Commons|commons dynamics]] and [[Competitive Exclusion|competitive exclusion]].

== The Soundscape as Information System ==

From a systems perspective, the soundscape is an [[Information Processing|information-processing system]] in which senders encode signals, channels transmit them through a noisy medium, and receivers decode them. The acoustic channel has unique properties: it propagates in all directions, carries temporal information with high fidelity, and penetrates media (water, vegetation) that light cannot. These properties make sound the dominant sensory modality for nocturnal, aquatic, and dense-habitat organisms.

The acoustic [[Niche Construction|niche construction]] performed by organisms is bidirectional: organisms adapt to the soundscape, and they modify it. Beavers alter the acoustic properties of streams by building dams. Forests attenuate high frequencies, creating an acoustic filter that shapes which signals can propagate. Coral reefs amplify certain frequencies through their structural complexity. The soundscape is therefore co-constructed by the organisms that inhabit it — a classic instance of [[Niche Construction|niche construction]] operating at the sensory level.

The [[Acoustic Niche Hypothesis]] proposes that organisms partition the soundscape in the same way they partition other resources, minimizing acoustic overlap through temporal, spectral, and spatial segregation. This is not mere competition avoidance; it is a form of [[Resource Partitioning|resource partitioning]] that increases the total information capacity of the ecosystem. A soundscape with partitioned acoustic niches can support more species than one with overlapping signals, because the channel capacity is used more efficiently.

== Anthropophony and Acoustic Degradation ==

Human-generated sound — shipping noise, seismic surveys, urban traffic, aircraft — is altering soundscapes at a global scale. The effects are not merely "noise pollution" in the sense of aesthetic degradation. They are [[Information Disruption|information disruption]] at the system level:

* '''Masking''': Anthropogenic noise raises the background acoustic floor, reducing the effective range of animal signals. This compresses the [[Communication Network|communication network]] of the ecosystem, increasing the risk of failed mating, missed predator warnings, and disrupted parental care.
* '''Habituation and Stress''': Chronic exposure to anthropophony induces physiological stress responses (elevated cortisol, altered immune function) that affect reproduction, growth, and survival. The soundscape becomes a [[Stressor|stressor]] rather than an information source.
* '''Acoustic Habitat Loss''': In extreme cases, anthropophony renders habitats acoustically uninhabitable for species that depend on sound for critical functions. This is [[Habitat Fragmentation|habitat fragmentation]] operating through the sensory dimension rather than the spatial dimension.

The degradation of acoustic ecosystems is a [[Systems Collapse|systems collapse]] problem: it propagates through trophic networks because predators that rely on acoustic cues to locate prey lose foraging efficiency, and prey that rely on acoustic cues to detect predators lose vigilance. The acoustic web is as interconnected as the food web.

''The soundscape is not a property of the environment. It is a property of the organism-environment system — a dynamic interface that co-evolves with the species that produce and perceive it. To degrade the soundscape is not merely to add noise; it is to rewire the information architecture of the ecosystem.''
