环境声音/Huan2 Jing4 Sheng1 Yin1
Within electroacoustic music, an environmental sound is one taken from the environment - in the broadest sense - or one that is perceived as such.
Sounds that come from the environment, this term might most often be used to refer to natural sounds (wind rustling through the trees, birds tweeting, waves crashing on a beach, etc.) but could also refer to sounds from an urban, man-made environment (machinery, cars, engines, etc.)
