ABSTRACT OF THE DISCLOSURE A system for suspending a receiver in a hearing aid and acoustically linking the receiver with the region external to the hearing aid. A shaped mandrel is placed inside the shell of the hearing aid and a liquid material is poured into the shell. The liquid material polymerizes to form an elastomer that is around the mandrel and in contact with the shell. The mandrel is when removed from the shell, leaving a receiver cavity and sound channel. A receiver is inserted into the receiver cavity. The receiver cavity holds the receiver, and the sound channel grippingly engages an acoustic output port on the receiver. The sound channel extends between the receiver and shell, acoustically linking the receiver with the external region.
