A temporary sound barrier system is provided, with two support columns, a stiffening structure fixed between the support columns, and at least two sound proofing curtain elements having top and bottom edges attached to the two support columns and over the stiffening structure. The hybrid Hall effect device can be used to determine the independent magnetic field vector components comprising a vector magnetic field, such as for determining the {circumflex over } and the {circumflex over } components of a magnetic field, or for measuring the total magnitude of a vector magnetic field of any orientation. An integrated adaptive array having a plurality of input cells, a plurality of output cells, or a plurality of both is also disclosed.
