The method also includes determining that a first frequency domain value corresponding to a first frequency bin is less than or equal to a first threshold value, and in response, updating the first frequency domain value based on a function of (i) a smoothing parameter, and (ii) a second frequency domain value corresponding to the first frequency bin. The second frequency domain value is computed using one or more preceding frames of the multiple frames. The method further includes determining a noise floor corresponding to the first frequency bin using the updated first frequency domain value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable-time smoothing for steady state noise estimation","description":"A method includes receiving multiple frames of time-domain data that includes noise, and computing, for a first frame of the multiple frames, a frequency domain value for each of multiple frequency bi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11264015","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
