Since I have bilateral CIs, my mapping and testing take longer than it would for someone who only has one CI. My appointments usually last anywhere from an hour and a half to two hours. If I have issues I need to discuss with my audi, sometimes I can be there for three hours. During my CI testing, I'm given a standard hearing test to determine which frequencies I'm not hearing well. I'm also given hearing tests to determine how well I can hear single words, sentences in quiet and sentences in noise. The number of words, sentences in quiet and sentences in noise is 50 each. Once my hearing tests are completed, my audi reviews the results with me and we proceed to map my CIs based on this information.
