Abstract

An acoustic reflector (10) comprises at least one elongate member (12, 14) having a plurality of reflector means (16) disposed around its axis. Various embodiments are discussed. In one two such members (12, 14) are mounted substantially orthogonally to each other. In another the reflectors are arranged in opposed pairs about an axis, adjacent pairs being rotated with respect to the next pair to enable each incoming acoustic waves from various directions to be reflected.
