The ultrasonic carrier signal, upon being reflected from the audio source, undergoes modulation by the audio source. The modulated ultrasonic signal may then be received by an ultrasonic microphone and demodulated to retrieve the audio. A highly directional microphone system is achieved through the use of the ultrasonic emitter and ultrasonic microphone, where the modulated ultrasonic signal only arises when the audio source is in the ‘beam’ of the ultrasonic carrier signal and the ultrasonic microphone can ignore other potential noise, ambient sound(s), etc."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Parametric transducer microphone system","description":"An ultrasonic emitter can launch an unmodulated ultrasonic carrier signal towards an audio source.
