Question 23

counseling: how would you explain test results using an age-appropriate and patient-friendly language

Question 24

how does a CI function start to finish

Answer 24

Microphone on the speech processor sitting behind the ear picks up the acoustic signal which converts it into electrical information, amplifies it, and sends to the speech processor
The speech processor cleans up and converts the electrical signal into digital signals to be sent to the external transmitting coil
The external transmitting coil sits outside on the skin and sends the digital signal information and power by radio frequency through the skin to the implant inside and its internal receiver
The internal receiver/stimulator decodes the digital signal and creates and sends electrical pulses to the electrode array in the cochlea via the lead
The electrode contacts? In the array stimulate the auditory nerve fibers with controlled electrical impulses for the brain to interpret as sound
*Amplitude, duration, and rate of the pulses are controlled by the speech processor

Question 25

what is the importance of addressing hearing loss in both adults and children, including its potential effects on communication, cognition, and development

Question 26

how does a CI function start to finish as if you were telling a patient

Answer 26

CI helps you hear by turning sounds into electrical signals the brain can understand To do so the tiny mic behind your ear picks up the sounds and sends it to a small computer called the processor that turns it into a special signal that is sent to the implant under your skin This implant then sends the signal to tiny wires inside your inner ear to stimulate your hearing nerve which is sent to the brain and it turns them into sound It doesn’t make your hearing normal but it can help you to hear and understand speech better. It takes time and practice to get used to and regular f/u appointments and listening therapy to get the best results
