The microphone, a second equalizer, a third mixer, and a second speaker are coupled in series forming a second signal path with a fourth mixer coupled to the second equalizer within the second signal path. A control interface may be coupled to at least one of the first equalizer and the second equalizer. A Bluetooth module may be coupled to at least one of the first equalizer and the second equalizer. A third equalizer may be coupled to input signal into the first signal path and a fourth equalizer may be coupled to input signal into the second signal path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Equalized hearing aid system","description":"An equalized hearing aid system includes a microphone, a first equalizer, a first mixer, and a first speaker coupled in series forming a first signal path with a second mixer coupled to the first equa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9843874","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.
