Nothing.
You can't hum when your nose is pinched because when you hum, air comes out of your nose, so when your nose is pinched, no air comes out. But you can hum with your nose pinched and your mouth open, it sounds a little different but it is similar to humming.
With your voice and out your nose. It is like singing, but it is usually done with the mouth closed.
humming is the sound of your vocal cords vibrating with your mouth closed. the air goes out through your nose. try pinching your nose when humming-
That process is known as humming. Unlike whistling or singing, humming is more of a reserved way of making a musical sound with your voice. Usually humming occurs when people close their mouth shut and make melodies with their voice.
Because you hum through your nose (try humming whilst holding your nose) it's doesn't work too well, so talking is like humming through mouth and nose so when your nose is stuffed one of the vital talking needs is cut off, leaving you talking funny like when you are humming funny. :)
When you hum you blow out air to make the noise, but if you plug your nose, no air comes out and you cannot hum. It is possible to hum for a short time with your nose plugged, but you will be unable to do so for very long or at any volume.
It blocks the air ways.
You tighten the muscles pulling on them as you exhale, so that they "hum" as you breath out. To make speech or song you use your mouth and tongue as an echo chamber to shape the hum into words or notes. If you hum with your mouth closed you'll hear what the vocal cords can do alone.
Nose PiercingOkay, hum, when you get your nose pierced, it swells, but only on the inside of your nose. The swelling is going down most probably. But I would go see a Doctor, just to be on the safe side.(:
