Abstract

The aim of this work is the consideration of the method of pure tone audiometry PTA)in the implanted patients. What is the value of the results of PTA? How to perform PTA of the implanted patients? Is there sense to perform PTA? We describe the methods for determining and setting the electrical threshold levels (T-levels)in the program of the speech processor of cochlear implant(CI).
