Abstract: An assembly includes an enclosure including first and second regions spaced apart along a first direction, and a plurality of spaced apart acoustic baffles arranged along a second direction different from the first direction and disposed in the enclosure between the first and second regions. The plurality of spaced apart acoustic baffles includes adjacent first and second acoustic baffles. Each of the first and second acoustic baffles include an acoustically absorptive layer disposed on a sheet having a specific airflow resistance greater than 200 MKS Rayl. The first and second acoustic baffles define a channel therebetween. At least a portion of the channel extends along a longitudinal direction making an oblique angle with the first direction.

Abstract: Provided are non-woven fibrous webs, methods and assemblies thereof. The non-woven fibrous web comprises a plurality of melt-blown fibers. The plurality of melt-blown fibers include a thermoplastic polymer blended with a phosphinate and/or polymeric phosphonate. The provided non-woven articles can afford a fine fiber diameter for enhanced acoustic insulation properties, dimensional stability, and superior flame-retardant properties when compared with conventional non-woven articles having similar fiber diameters.
