Abstract
An acoustic attenuator and wax barrier for a hearing aid includes a substantially cylindrical, color coded, housing having a barbed portion for press-fitting the barrier into position. As the channel diameters increase, an associated peak output frequency also increases for the respective housing. The barrier may include one of a plurality of attenuating or damping screens which provides predetermined sound damping characteristics. Alternately, the barrier may include housings having different acoustic channel diameters to provide the different, predetermined audio attenuation or damping characteristics. The barrier is field changeable and is more easily inserted than removed. The barrier may be provided as part of a system which includes a tool for performing field replacement of the barrier.
