  • Radio frequency shielding for receivers within hearing aids and listening devices
    Patent number: 7460681
    Abstract: 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.
