    摘要: Acoustic valve capable of selective and non-linear filtering of sound and placeable in a perforated ear plug. The acoustic valve consists of a tube enclosing two rigid disks axially spaced opposite each other, each of the disks containing at least one perforation. The total perforated surface of at least one disk is between 0.03 and 0.5 mm.sup.2.
