The outputs of the first and second A/D converters are input to the microphone sensitivity correction value calculation unit. One output the microphone sensitivity correction value calculation unit is connected to the microphone sensitivity correction unit, and another output thereof is connected to the storage unit. An output of the storage unit and a signal output from the another output of the microphone sensitivity correction value calculation unit are input to the failure detection unit. Output signals of the failure detection unit and the hearing assistance processing unit are input to the sound output unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hearing aid","description":"A hearing aid includes: first and second microphones; first and second A/D converters; a microphone sensitivity correction unit; a hearing assistance processing unit; a microphone sensitivity correcti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8494194","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.
