Nureva announced that the United States Patent and Trademark Office and European Patent Office have issued three additional patents for the company’s Microphone Mist technology, the platform behind every Nureva audio system. These patents “underscore Nureva’s commitment to reinventing the way that pro audio conferencing performance is achieved in larger spaces.” Nureva says the patent authorities have acknowledged the company’s approach to intelligent sound targeting, position-based gain control and echo cancellation, all of which help to deliver the clear and natural speech intelligibility that greatly benefits remote students and meeting participants. The patents represent the latest additions to the company’s active and growing intellectual property portfolio, which provides Nureva with significant opportunities to develop new products and enhancements.

US 11,689,849 discloses the ability of the microphone array to preemptively identify semi-persistent unwanted sound sources such as HVAC systems and fans and exclude them during the targeting process. These intelligent sound identification capabilities elegantly and efficiently enhance the listening experience.

US 11,635,937 discloses the ability of the microphone array to use sound-source position-based gain control processing to make specific optimizations to the microphone system. This approach optimizes the talker’s gain while maintaining ambient noise at a quieter and more consistent level, enabling more natural conversations. Additionally, it effectively overcomes the limitations and distractions caused by common issues with automatic gain control hysteresis and level pumping.

EP 3791565 discloses the use of residual echo estimate information to derive secondary echo reduction parameters. This approach significantly enhances the acoustic return echo cancellation performance, ensuring talkers don’t hear their own voice in their headset or speaker after speaking, regardless of the UC&C client being used.
