Abstract
A hearing aid appliance has induction loops which are magnetically coupled to hearing aids held individually by hard-of-hearing persons. The number of induction loops is an integral multiple of two, and each induction loop is in the form of a rectangle having at least two parallel sides. The parallel sides of the induction loops are arranged in parallel with one another and equally spaced from one another so that signal currents flowing in adjacent parallel sides are shifted by 90.degree. in phase.
