Method and apparatus are disclosed for reducing or eliminating the
interference produced by a receiver in a listening device, such as a
hearing aid. The method and apparatus of the invention involves placing
an electrically conductive shield around the receiver. Such a shield
helps suppress the electromagnetic signals emitted by the receiver,
thereby reducing or eliminating the interference from the receiver. The
shield is a passive shield and may be one or more wires that are wound
around the receiver and shorted together, or it may be an electrically
conductive mesh, jacket, sleeve, or the like, that is placed around the
receiver. The shield is then connected either to one of the input
terminals of the receiver, or to a system ground of the receiver.
