It made possible more realistic overall measurement of hearing aid performance by taking into account the acoustic effects of the body, head, pinna, and ear canal. It mechanically causes the ossicles to vibrate; the amplified vibrations are adjustable to optimally compensate for hearing loss. Phonak introduces the miniValeo – it is the first Phonak model to use thin tubing instead of the traditional earmold. All the hearing aid components were concealed in a shell which was actually worn at the ear rather than in the ear. The history of Deaf people, from ancient times to the present, reminds us of other stories of oppressed people who struggled for self- determination. Siemens introduces a programmable CIC in 1996.
