Technology ….from the hearing perspective
Amplification • The backbone of the hearing perspective (underlying premise) • “we want the child to hear/speak” • “we want the child to be like us” (90% of Dhh children are born to hearing parents) • the Deaf world is different and scary!

One-piece vacuum tube body aid (1947). This was the first model of hearing aids made with a printed circuit, and the model on display is the 5th such model made with the printed circuit.
Analog hearing aids amplify sounds -- the trouble is they amplify all sounds equally • Digital hearing aids contain a computer chip, which analyzes the sound based on the person's hearing loss and listening situation, and then amplifies it in a way that accommodates for the volume and pitch of incoming sounds. It even adjusts for feedback. Like analog hearing aids, digital aids can be programmed for a variety of listening environments.

Cochlear implant • A cochlear implant is not the same thing as a hearing aid. • One part of the device is surgically implanted into the temporal bone (the bone surrounding the ear). It consists of a receiver-stimulator, which accepts, decodes, and then transmits an electrical signal to the brain. • The second part consists of a microphone/receiver, a speech processor, and an antenna. It receives the sound, converts the sounds into an electrical signal, and transmits it to the internal portion of the cochlear implant.

Such concentration on auditory signal is necessary that visual input will weaken the ability to “hear” and thus “speak” optimally.
