In the burgeoning field of urban acoustic ecology, researchers analyze soundscapes to gauge environmental health. A soundscape is traditionally partitioned into three acoustic sources. The first, biophony, encompasses all vocalizations and acoustic signals generated by non-human biological organisms within a given habitat. The second, geophony, refers to naturally occurring, non-biological ambient sounds, such as the rustling of leaves in the wind or the flow of a river. In urban environments, however, the dominant acoustic layer is often anthrophony—the aggregate of sounds produced by human activity, including mechanical noise and vehicular traffic. When anthrophony saturates an environment, it can disrupt the acoustic niche of local wildlife, defined by ecologists as the specific time or frequency window an organism utilizes to ensure its acoustic signals are not masked by competing sounds.
Based on the passage provided, match each specialized term to its author-stipulated definition.
- BiophonyThe collection of acoustic signals produced by non-human living organisms.
- GeophonyNon-biological ambient noises originating from natural, physical processes.
- AnthrophonyThe combined auditory output resulting from human presence and mechanical processes.
- Acoustic NicheA designated frequency range or temporal period an animal uses to avoid signal interference.
