What is the “silent cough?
The silent cough technique is a way to clear the throat without violently banging the vocal folds together. The silent cough is done by breathing in air and blowing the air out fast through your throat and mouth without making a sound. Immediately after the silent cough, you should tuck your chin down toward your chest and make a strong swallow. The silent cough often clears mucous that clings to the vocal folds or near them. The silent cough is an important element of vocal hygiene and helps to prevent unnecessary trauma to the vocal folds. It is especially important to use the silent cough after surgery to the vocal folds.
