What should I do if my hearing is not satisfactory or noise affects me after surgery? How do I adjust my cochlear implant? How many adjustments are needed? If the preoperative diagnosis of the cochlear implant is clear and the surgery is successful, the main reason for poor hearing or noise after surgery is improper adjustment. Generally speaking, after the cochlear implant is switched on and adjusted by a professional audiologist, the patient’s ability to adapt to the cochlear implant changes from a “soft sound” to a “maximum and most adaptive sound”, which generally takes 0-3 months. Since modern intelligent cochlear implants are designed with multiple programs and tone adjustments, there is no longer a need for too frequent post-operative commissioning, which is generally done once a month for the first 3 months after start-up and 1-2 times a year thereafter. The cochlear implant reconstructs natural sound, so after surgery, in addition to being able to hear and hear beneficial sounds such as speech and music, patients can also hear noise like normal people. Therefore, the patient needs to gradually adapt to the recognition of human speech sounds in a noisy environment. If the patient is significantly uncomfortable with the background noise of speech in the short term, the cochlear implant can be adjusted to reduce the noise appropriately, and then adjust the noise scheduling to normal levels after gradually adapting to the background noise, in order to achieve the natural ability to discriminate between environmental sounds and speech sounds.
