Behind the ear hearing system |
(57) The invention relates to a method of manufacturing a sound tube for a hearing aid.
The method comprises the steps of:
positioning a preformed wire within the tube, heating the tube or exposing the tube
to UV light, whereby the tube accommodates to the shape of the preformed wire, and
removing the preformed wire from the tube, whereby the tube retains the shape of the
preformed wire.
