When you do a vocal cord examination, you need to see the closure of the vocal cords and whether there are vocal cord nodules. Generally, a laryngoscope is required. Most hospitals will have a laryngology department, which can be done for about 300 yuan. After an examination, the doctor will use a tube with a camera from your nasal cavity to your pharynx. This process is relatively uncomfortable, but you can see through the monitor next to the doctor that the camera enters the nasal cavity and ends in your pharynx. During the whole process, the doctor will ask you to perform a series of actions, such as making a "1" sound or an "ah" sound, and then it will end. The whole process will probably take less than 10 minutes, and you will be able to do it after a while. You can wait for the report. The doctor will attach a few photos of a series of movements taken from your pharynx, which you can keep as a souvenir.

PS: Don’t yell when nothing happens. There are many college classmates from the Northeast around me. It is said that their physical fitness is better than that of children in the south, so they become more confident when they sing high notes and yell loudly when nothing happens. However, teachers often warn that doing so is bad for your voice. If you have not formed a skilled singing and vocal habit and system, you should turn on your voice before singing. Just like a car in the running-in period, you still need to WARM UP before going out. It will play a protective role. The vocal cords are relatively fragile. If they are used incorrectly often, there is a possibility of vocal cord nodules. Vocal cord nodules need to be removed surgically. If you are a little hoarse, I don’t know the specific situation. You can go Get a checkup.

Hope this helps.
