Abstract
An assembly includes an acoustic device. The acoustic device can include a polyethylene membrane. The polyethylene membrane can have first direction and a second direction, the second direction being orthogonal to the first direction. The polyethylene membrane can have a surface area per volume of at least 39×10/m. The polyethylene membrane can have a geometric mean tensile modulus of 250 to 750 MPa. The polyethylene membrane can have a maximum tensile modulus in the first direction of 440 to 915 MPa. The polyethylene membrane can have a maximum tensile modulus in the second direction of 275 to 515 MPa. The polyethylene membrane can be an expanded polyethylene membrane.
