ABSTRACT:
A hearing device has an electrical/acoustical output converter that communicates with ambient air through a membrane. The membrane separates two spaces. Each space communicates with ambient air through a passage that substantially blocks acoustical signals in the range of the audible spectrum and passes acoustical signals at a frequency lower than the audible spectrum.
