  • Publication number: 20170188157
    Abstract: The present invention relates to a microphone with a specific audible area using ultrasound wave, which emits an ultrasound wave toward a sound source positioned in a specific area within a desired distance and a desired direction from the microphone, and extracts a sound signal in an audible frequency range, generated by the sound source, from an ultrasound wave reflected and received from the sound source. The microphone with a specific audible area using ultrasound wave can limit the audible area to an area within a specific angle from a half line starting from the microphone and a specific distance from the microphone, such that a user can selectively hear a desired sound in a noisy environment. When the microphone is applied to a hearing aid, the user can hear only the audible sound generated by the sound source located within the specific audible area in front of the user with the surrounding noise removed.
