A film includes 20.0 weight percent to 69.5 weight percent of a linear low density polyethylene (LLDPE) based polymer. The LLDPE having a high density fraction (HDF) from 3.0% to 8.0%, an I/Iratio from 5.5 to 6.9, and a short chain branching distribution (SCBD) of less than or equal to 8.0° C. The film also includes 0.0 weight percent to 10.0 weight percent low density polyethylene (LDPE) based polymer, and 30.0 weight percent to 70.0 weight percent pore former.

A sound barrier system for use in mitigating noise having an origami sheet or origami-inspired mechanism that can use folding to change configuration and lattice topology; and a plurality of cylindrical inclusions disposed on top of the origami sheet. The plurality of cylindrical inclusions being periodically arranged such that folding kinematics of the origami sheet induces reconfiguration of the periodicity of the plurality of cylindrical inclusions and associated wave blocking of the noise.
