The signal processing unit determines time responses of the first input signal and the second input signal based on a contact sound generated when the hearing aid is contacted in a predetermined time period, and distinguishes a plurality of settings of the hearing aid and changes the setting based on the time responses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hearing aid and hearing aid system","description":"A hearing aid includes: a first microphone configured to generate a first input signal from an input sound; a second microphone configured to generate a second input signal from the input sound; a sig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488825","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.
