Yes, it does, but fully
The flame itself does not, at least, not a noticeable one, however, you can sometimes hear the gas leaving the source.
The hissing noise is most likely the gas moving through the line. Anything that uses gas will make this sound.
If you let hydrogen gas near the flame it will pop. The way we got hydrogen gas is by adding hydrochloric acid to magnesium powder and putting our thumb over the top of the test tube trapping the hydrogen gas then releasing it near the flame of the Bunsen burner.
Green flame cuz when the air hole is closed it is yellow and when it is open it is blue so when the colors are combined they make the green flame

Air hole open=steadyAir hole closed= not steady.Why?Lack of oxygen makes the flame unsteady when the hole is closed as oxygen is used for burning.
It is closed to make a safety flame.
close the air hole by twisting the collar
It makes a noise because of vibrations in the hole is the middle
Madagascan hissing cockroaches make a noise by forcing air out of a special hole.
To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.
You decide how big a whole hole is and then measure out half of that. Unless you're English - the English claim there is no such thing as half a hole.
By using the correct ratio of oxygen and fuel mixture. Opening the air hole in the Bunsen burner increase the oxygen which helps the flame burner hotter .
You have to have a table and cut a hole in it and make it go though the hole. Make sure not to make noise.
