Abstract
A hearing aid housing which is formed of a substantially rigid plastic material carries a deformable compliant region. The region, which could be in the form of an annular seal, or which could extend in part axially along the housing improves user comfort and hearing aid performance by providing an improved seal with the user's ear canal. The housing can be formed with a substantially constant wall thickness which includes the regions wherein the compliant material is located.
