DEVICES, METHODS, SYSTEMS, AND MEDIA FOR SPATIAL PERCEPTION ASSISTED NOISE IDENTIFICATION AND CANCELLATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18463768 titled 'DEVICES, METHODS, SYSTEMS, AND MEDIA FOR SPATIAL PERCEPTION ASSISTED NOISE IDENTIFICATION AND CANCELLATION

Simplified Explanation

The patent application describes devices and methods for cancelling sounds at a listener's location by identifying sound sources in the environment and generating anti-noise signals to cancel out the sounds originating from those sources. Here are the key points:

  • Sound sources in the listener's environment are identified using microphones or remote devices.
  • The user is provided with information about the sound sources and prompted to select the ones they want to cancel out.
  • Microphones are used to monitor for sounds from the designated sources.
  • The captured audio information is processed to generate anti-noise signals that cancel out the sounds from the selected sources.
  • Multiple sound sources can be designated as noise while leaving others unfiltered.
  • The technology can be used for single-listener and multi-listener applications, as well as for listening and speaking purposes.

Potential Applications

This technology has various potential applications, including:

  • Noise cancellation in headphones and earphones, providing a more immersive and quiet listening experience.
  • Enhancing speech recognition systems by cancelling out background noise during conversations or voice commands.
  • Improving audio quality in teleconferencing and video conferencing systems by reducing unwanted noise from the environment.
  • Noise cancellation in vehicles, reducing road and engine noise for a more comfortable ride.
  • Noise cancellation in public spaces, such as airports or offices, to create quieter and more focused environments.

Problems Solved

This technology addresses several problems related to unwanted noise:

  • It allows users to selectively cancel out specific sound sources, reducing distractions and improving focus.
  • It improves the clarity of audio signals by eliminating unwanted background noise.
  • It enhances the performance of communication systems by reducing interference from surrounding sounds.
  • It provides a more enjoyable and immersive listening experience by eliminating unwanted noise in headphones or earphones.

Benefits

The benefits of this technology include:

  • Improved concentration and focus by eliminating distracting sounds.
  • Enhanced audio quality in various applications, such as music, movies, and phone calls.
  • Increased speech intelligibility in noisy environments, improving communication.
  • Customizable noise cancellation, allowing users to select which sound sources to cancel and which to keep.
  • A more comfortable and enjoyable listening experience with reduced background noise.


Original Abstract Submitted

Devices, methods, systems, and media for selectively cancelling sounds at a listener's location are described. Sound sources are identified in the listener's environment using microphones and/or remote devices associated with specific sound sources. A user is presented with information identifying the sound sources, including spatial information, and prompting the user to select one or more of the sound sources. After the user designates a sound source as noise, microphones are used to monitor for sound originating from the designated sound source, and the audio information captured by the microphones is processed to generate an anti-noise signal presented to the listener to cancel sounds originating from the selected sound source. A user may designate multiple sound sources as noise and leave other sound sources unfiltered. The techniques may be used in single-listener and multi-listener applications, and in listening and speaking applications.
