The hearing aid further comprises e) a feedback estimation system for estimating a current feedback from the output transducer to each of the at least two input transducers and providing respective feedback measures indicative thereof; and f) a controller configured to receive said feedback measures from said feedback estimation system and to switch between two modes of operation of the hearing aid, a one-input transducer (e.g. omni-directional) mode of operation, and a multi-input transducer (directional) mode of operation, in dependence of the feedback measures. to. The application further relates to a method of operating a hearing aid. Thereby the gain provided by the hearing aid to the user (without a significant risk of howl) can be maximized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hearing aid comprising a directional microphone system","description":"A hearing aid comprises a forward path comprising a) at least two input transducers, each for picking up sound from the environment of the hearing aid and providing respective at least two electric in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11463820","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.
