The acoustic filter is adapted to provide the selection of the attenuation from a sequence of predetermined attenuations based on a selection of the control signal. Each attenuation in the sequence corresponds to acoustic valves providing the apertures with a respective predetermined acoustic resistance, wherein the acoustic resistances of subsequent attenuations in the sequence are adapted to correspond with a linear increase or decrease in the attenuation of the sound in decibels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Acoustic filter with attenuation control","description":"An acoustic filter including a valve system with acoustic valves arranged in a sound passage for controlling the acoustic resistance of respective apertures based on a control signal for selecting an ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11266532","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.
