TL;DR: In this paper, the authors present a model for the analysis of variance in a single-classification and two-way and multiway analysis of Variance with the assumption of correlation.

Ecological Sources of Selection on Avian Sounds
TL;DR: In this article, sound propagation tests were made in forest, edge, and grassland habitats in Panama to quantify pure tone and random noise band sound transmission levels, and the sounds of birds in each habitat were analyzed to determine the emphasized frequency, frequency range, and sound type (whether pure tonelike or highly modulated).

Sound transmission and its significance for animal vocalization: II. Tropical forest habitats
TL;DR: Two facts mitigating against Morton's sound “window” as an explanation for lower frequencies in songs of forest as opposed to open country birds are presence of similar “windows” in both habitats and restriction of windows to a zone close to the ground in most habitats.

The importance of atmospheric attenuation for the echolocation of bats (Chiroptera)
TL;DR: The adaptive advantages of various frequencies for an echolocating bat are thus humidity dependent, and may explain the use of 8 to 4 kHz orientation sounds by an unidentified insectivorous bat in the Amazon Valley.

Noise reduction by vegetation and ground
TL;DR: In this article, the relation between attenuation and frequency in these diverse cases suggested models that permit the prediction of attenuation in any configuration of vegetation and soil, including corn, hemlock, pine, brush, and brush.
