Migliozzi says they decorate their world with sound in the same way that sighted people adorn their walls with pictures, posters, and other memorabilia. Once we have confirmed the diagnostic prosthetic socket fits the patient well, we can move on to the laminated socket. The acoustic signal is 'beeping' with a frequency proportional to the distance, i.e. Once limb volume has stabilized and the diagnostic prosthetic socket fits the patient well, we can move on to the laminated socket.
