passive acoustic monitoring

Passive acoustic monitoring (PAM) is a technique used to listen for sounds in the environment without disturbing wildlife or their habitats. It involves placing underwater or terrestrial microphones, known as hydrophones or acoustic sensors, to record natural sounds made by animals, such as whales, birds, or insects. Researchers analyze these recordings to study animal behavior, communication, and populations. PAM is valuable for conservation efforts, helping to monitor species in their natural habitats while minimizing human impact. It provides insights into ecosystems and helps inform strategies for protecting biodiversity.
