Acoustic signals must be transmitted from a signaller to a receiver during which time they become modified. The acoustic adaptation hypothesis suggests that selection should shape the structure of long-distance signals to maximize transmission through different habitats. A specific prediction of the acoustic adaptation hypothesis is that long-distance signals of animals in their native habitat are expected to change less during transmission than non-native signals within that habitat.

Can the acoustic adaptation hypothesis predict the structure of Australian birdsong?

The finding that birds in open habitats produced higher frequency vocalizations and greater bandwidth vocalizations is consistent with hypotheses about signal structure facilitating auditory distance assessment, and forest birds may therefore rely on cues other than frequency-dependent attenuation for ranging.

Song variation and habitat structure in the Golden Bowerbird

It is suggested that local habitat structure has relatively little effect on the design of acoustic signal in the Golden Bowerbird at the individual level, while efficiency of transmission may influence signal design on evolutionary time-frames.

Testing the acoustic adaptation hypothesis with native and introduced birds in Hawaiian forests

AbstractThe acoustic adaptation hypothesis (AAH) states that animals communicating acoustically adapt their vocalizations to the local conditions to optimize signal transmission. We tested select

Geographic variation in marmots’ alarm calls causes different responses

Alpine marmots have dialects in alarm calls and discriminate their own dialects from others, being more frightened by alarm calls from another population than by those from their own, indicating how predation pressure, and more widely natural selection, could drive the evolution of communication.

A test of the Acoustic Adaptation Hypothesis in three types of tropical forest: degradation of male and female Rufous-and-white Wren songs

A significant difference is shown between transmission characteristics of both male and female song elements across the three habitats, indicating that sounds transmit differently through different types of tropical Forest, and reveals some sex differences in transmission properties.

The effect of body size and habitat on the evolution of alarm vocalizations in rodents

The results of the present study show that the acoustic frequencies of alarm calls can provide reliable information about the size of a sender in this taxonomic group, although they generally do not support the acoustic adaptation hypothesis.


Overall, evidence for the acoustic adaptation hypothesis was not as widespread as expected across taxa, and environment-related adjustments in structure of vocal signals seem to be constrained by call function in anurans and mammals.

Variation in pika ( ochotona collaris, o. princeps ) vocalizations within and between populations

Geographic call variation in these two species of pikas likely reflects genetic divergence, and may be a result of separate evolutionary histories, and the potential for individual coding for both time and frequency measurements of calls was calculated.

Reduced geographic variation in roars in different habitats rejects the acoustic adaptation hypothesis in the black‐and‐gold howler monkey ( Alouatta caraya )

The combination of high amplitude and low peak frequency of roars, coupled to small home range size and extensive overlap between neighboring groups, allows roars to keep their communication value across habitats without need of specific environmental tuning.



Sound Transmission: a Basis for Dialects in Birdsong?

The environmental adaptation hypothesis (EAH) regarding birdsong dialects or ncighbourhoods states that song similarities between neighbouring individuals arise because of common influences on their

Predictions From the Ranging Hypothesis for the Evolution of Long Distance Signals in Birds

The predictions of the RH include distance assessment mechanisms, DAMs; it is proposed that these have opened a new evolutionary process illustrated by the complicated songs and singing behaviour in the oscine passerines, and emphasizes the ecological basis for the evolution of long distance communication.

Song transmission and auditory perception of distance in wood warblers (Parulinae)

The results from transmission and playback experiments are discussed with respect to the ranging hypothesis, which proposes that selection should favour males that structure songs to minimize their degradation, so that songs function to disrupt or intimidate rivals by providing unreliable distance cues.

Alarm calling in yellow-bellied marmots: I. The meaning of situationally variable alarm calls

Yellow-bellied marmots, Marmota flaviventris were reported to produce qualitatively different alarm calls in response to different predators, but there was significant individual variation in call structure, but acoustic parameters that were individually variable were not used to communicate variation in risk.

Associations of Song Properties with Habitats for Territorial Oscine Birds of Eastern North America

The results suggest that the temporal properties of songs of many oscines have evolved to reduce the effects of reverberation in forested habitats, and Exceptional species might have retained features of song subject to degradation to permit listeners to judge distances to singers.

The Association between Vocal Characteristics and Habitat Type in Taiwanese Passerines(Ecology)

The vocalizations of twelve Taiwanese passerines were analyzed to examine whether vocal characteristics are associated with habitat type: edge, forest canopy, and forest floor, and to test two hypotheses: 1) whether birds of forested habitats vocalize at lower frequencies and with less variance and slower repetition rates than do birds of open edge areas; and 2)Whether birds of the forest floors are subjected to the most stringent effects of attenuation.

The Role of Body Size, Phylogeny, and Ambient Noise in the Evolution of Bird Song

There has been an evolutionary response to selection for low-frequency songs by birds in low-forest habitats, according to the constraints of body size and evolutionary history, and the spectral distribution of ambient noise as an additional selective factor is examined.

Acoustic signal amplitude patterns : A computer simulation investigation of the acoustic adaptation hypothesis

The results show strong support for the AAH predictions regarding what type of signal structure is best suited for open or closed habitats, however, this support is based on variability in performance of signal types in different habitats rather than average transmission quality.
