The hearing device further comprises a feedback reduction unit for reducing a risk of howl due to feedback from the output transducer to the input transducer. The forward path and the external feedback path defines a roundtrip loop delay. The feedback reduction unit is configured to modulate said requested forward gain in time, to provide that the resulting forward gain exhibits a first, increased gain AH in a first time period TH and a second, reduced gain AL in a second time period TL, wherein at least one of AH, AL, TH, and TL is/are determined according to a predetermined or adaptively determined criterion including said roundtrip loop delay."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hearing device comprising a feedback cancellation system based on signal energy relocation","description":"A hearing device, e.g. a hearing aid, is provided, comprising a forward path comprising an input transducer for providing an electric input signal, a signal processing unit configured to apply a reque","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9826319","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.
