ABSTRACT:
A connector connects sound conduction tubing from a hearing aid to a sound conduction bore in an earmold. The connector is an elbow-shaped member with one end receiving a filter and an end of the sound conduction tubing while the other end has latching means that latchably mate with an entry section of the sound conduction bore. The inside diameter of the sound conduction tubing, the diameter of a sound conduction tubular passage in the elbow-shaped member and the diameter of the sound conduction bore are the same theralong thereby defining a continuous flow sound conduction path from the hearing aid to the end of a canal of the earmold.
