context_page_description: A parabolic microphone is a microphone that uses a parabolic reflector to collect and focus sound waves onto a transducer, in much the same way that a parabolic antenna does with radio waves. Though they lack high fidelity, parabolic microphones have great sensitivity to sounds in one direction, along the axis of the dish, and can pick up distant sounds. Typical uses of this microphone include nature sound recording such as recording bird calls, field audio for sports broadcasting, and eavesdropping on conversations, for example in espionage and law enforcement. Parabolic microphones were used in many parts of the world as early as World War II, especially by the Japanese.
