A logic circuit is operatively associated with the ASM and ECM calculates a total SPL_Dose experienced by the ear at a time t. The total SPL_Dose is calculated by determining SPL_Dose for periods Δt as measured at the ECM. The logic circuit may select an action parameter in response to the Total SPL_Dose."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Earhealth monitoring system and method IV","description":"A system for monitoring sound pressure levels at the ear includes an ambient sound microphone (ASM) for receiving ambient sounds and an ear canal microphone (ECM) for producing audio signals as a func","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462956","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.
