WIND NOISE REDUCTION, FLEXIBLE BEAMFORMING, AND DIRECTION OF ARRIVAL ESTIMATION BY MICROPHONE PLACEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240015433 titled 'WIND NOISE REDUCTION, FLEXIBLE BEAMFORMING, AND DIRECTION OF ARRIVAL ESTIMATION BY MICROPHONE PLACEMENT

Simplified Explanation

The patent application describes an image capture device that includes a housing, a processor, and three or more microphones. The microphones are configured to capture sound, and the processor is configured to process the sound captured by the microphones. The first microphone is located on or within the forward wall of the housing, the second microphone is located on or within the top wall of the housing, and the third microphone is also located on or within the top wall but spaced apart from the second microphone.

  • The image capture device includes a housing, a processor, and three or more microphones.
  • The microphones are configured to capture sound.
  • The processor is configured to receive the sound from the microphones and perform various functions such as estimating a direction of arrival, reducing or removing wind noise, and performing beamforming.
  • The first microphone is located on or within the forward wall of the housing.
  • The second microphone is located on or within the top wall of the housing.
  • The third microphone is located on or within the top wall of the housing and spaced apart from the second microphone.

Potential Applications of this Technology:

  • Improved audio capture in image capture devices such as cameras or smartphones.
  • Enhanced audio recording for video production or live streaming.
  • Noise cancellation and wind noise reduction for outdoor recording.

Problems Solved by this Technology:

  • Wind noise interference during audio capture.
  • Difficulty in capturing audio from specific directions.
  • Poor audio quality in noisy environments.

Benefits of this Technology:

  • Improved audio quality in image capture devices.
  • Enhanced user experience in capturing audio.
  • Better audio clarity and reduced background noise.


Original Abstract Submitted

an image capture device includes a housing, a processor, and three or more microphones. the housing includes a forward wall including a sensor, a rearward wall located opposite the forward wall, and a top wall connecting the forward wall and the rearward wall. the three or more microphones are configured to capture sound. the three or more microphones include a first microphone, a second microphone, and a third microphone. the processor is configured to receive the sound from the three or more microphones and to estimate a direction of arrival, reduce or remove wind noise, perform beamforming, or a combination thereof. the first microphone is located on or within the forward wall, the second microphone is located on or within the top wall, and the third microphone is located on or within the top wall and spaced apart from the second microphone.
