Post-implantation performance assessment
A lot of audiological tests assesses performance in implanted children, It also has a profound impact on all aspects of communication, and the assessment for children should be broad enough to reflect these changes. After implantation the audiological tests can address a lot of perceptual and language skills in children , and it change from child to other depend on a lot of things such as duration of use the device and, in addition, preoperative variables. For this reason testing should survey a range of levels of speech recognition from simple awareness of sound, to pattern perception (discrimination of time and stress differences of utterance), to close-set (multiple choice) and open-set (auditory…show more content… Tests of speech perceptions typically consist of closed-set tests that assess word identification through limited set of options with auditory cues only, open-set tests that are scored by rate of individual word correctly repeated, and structured interviews of parents using criteria-based surveys to assess their planted child’s behaviors and reaction to sound in everyday situations.
Results of implantation in children
The House-3M was the first cochlear implant , it was single-channel device that consists of three main components: (1) the signal processor, (2) the signal transmitter/receiver, and (3) the implanted electrodes..
A lot of studies found that implanted children obtain substantial improvement in auditory thresholds and closed-set speech recognition and limited open-set speech recognition, and other studies observed that children who acquired deafness congenital or prelingually gain substantial speech perception after
