Abstract:
Echolocation is a complex biological traits that collaborated by multiple systems. Its origin can be traced back to 68 million years ago, and repeatedly appeared in multiple vertebrate groups in the subsequent biological evolution. The strong vitality has become a typical case of the convergence evolution in nature. However, it was not until the beginning of the 20th century that humans really opened the prelude to the research on animal echolocation, and became research hotspots in the fields of zoology, behavior, and genetics, and achieved rich results in the past 80 years. In this review, we summarize the development history of animal echo positioning, summarize different echo positioning animal groups in detail, and focuse on the research progress of echo positioning in sound mechanisms, acoustic characteristics, and high-frequency listening mechanisms in order to provide reference for comprehensive understanding of animal echo positioning.

Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
