Abstract
In this article we present generalized theoretical models of mate attraction in acoustic communication.The models use simple decision rules for females and show theoretical differences between the rules in relative attraction of females to sound sources (calling males). The important variables of the models are the relative powers of the sources, the distance between the sources and the number of competing signalers.Relative attraction among sources is a function of their relative power output with more powerful signals attracting more females. Using different assumptions about the spacing of sources with respect to female sensitivity, data from phonotaxis studies can be explained well by either random pick or active choice models. Bioacousticians must reexamine their use of, and conclusions based on, the two-choice playback paradigm in studying female mate choice.
