A barrier component, formed as a housing, covers a sound emitting opening to inhibit sound from emanating from the housing, except at an open end of the housing. Each sound emitting opening in the working unit or structure requires a housing positioned over same. The housing includes a hood portion and an elongate portion that includes the open end of the housing. The inner surfaces of the hood portion and an elongate portion are lined with sound absorbing material. The emitted sound first enters the hood portion, is partially absorbed therein and any unabsorbed sound passes into and is substantially absorbed in the elongate portion as the sound travels towards the open end of the housing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perforation acoustic muffler assembly and method of reducing noise transmission through objects","description":"A rugged noise muffler system is configured to substantially surround sound-emitting openings in a working unit or structure, to absorb sound emitted from the sound-emitting openings.
