You'll notice this if you gulp some water down very quickly, your throat makes a 'gulg, gulg' kind of sound, why does this happen? What is making that noise?

[Chelsie]

My thoughts are that when we quickly take a large swallow of food or water we produced more powerful esophageal contraction than the little swallows. Perhaps this is causing the gulping noise. It could also do with the fact that when we drink something quickly, we swallow a lot of air. That's all I've got for this one and my physio books have nothing.  [xx(]

Could is possibly be the epiglottis moving very quickly up and down?

[Chelsie]

Could be! I hadn't considered it. More forceful swallowing could potentially be causing the epiglottis to project stronger and make more noise.

Haha, you can? Sorry, my memory is a bit dodgy. Or maybe not?  [] []

Sorry, I took that out because I thought it sounded unreasonable after I wrote it. But if you contract your throat muscles, you can get movement from the epi. Another thought would be that when we swallow the larynx quickly moves upwards which could create some sound.
