A passive acoustic monitor is a device used to detect and record sounds in the environment without actively emitting signals. It captures sounds made by wildlife, such as birds, marine animals, or other natural phenomena, allowing researchers to study animal behavior and biodiversity. These monitors are often deployed in remote locations to gather data over extended periods. The data collected by passive acoustic monitors can be analyzed to identify species, track population changes, and assess habitat health. This technology is valuable for conservation efforts and ecological research, providing insights into the dynamics of ecosystems and the impact of human activities on wildlife.
