process information from secondary sources to evaluate a hearing aid and a cochlear implant in terms of: the position and type of energy transfer occurring conditions under which the technology will assist hearing limitations of each technology Hearing aids and cochlear implants Hearing aid or cochlear implant can be used to improve hearing (depending on the type of hearing loss) Device Hearing aid Cochlea implant (bionic ear) Sound energy; Electrical energy; Electrical Type of energy energy energy transfer Sound energy Radio energy; Electrochemical energy Battery-operated electronic device that Works by bypassing the damaged Information fits into the hollow just outside ear area of the ear + stimulating canal auditory nerve directly by amplifying sound waves within Receiver surgically implanted into the ear canal (making them louder), patient’s skull (fine wires attach increasing the energy being transmitted receiver to cochlea) through the ear Microphone behind patient’s ear Consists of a: picks up sound + transfers it to speech processor (worn on belt or Microphone receives – in pocket) waves + changes them into electrical energy Processor converts sound into a digital signal (electrical energy) Amplifier makes signal – stronger Signal transmitted to transmitting coil which sends message as FM Receiver changes electrical – radio signal to cochlea implant energy into sound energy (under the skin) Speaker directs sound energy – Attached wires stimulate auditory into auditory canal nerve which transmits signal to brain Conductive hearing loss Profound hearing loss Hearing (deafness caused by condition damage to inner ear)
