Is another trip to Hanoi in order?

Since being in Egypt, J and I have often tried to determine if Cairo is noisier than Hanoi, Vietnam or Tirana, Albania.  When we arrived in Hanoi a couple of years ago, I dubbed it Hanoi(se) and declared it the noisiest city I had ever been to.  We then spent two months in Albania, our apartment located at a busy intersection, and after rereading my  first post about that experience, I see I declared the city loud, but not as loud as Hanoi. So, we have that.  

Now, down to Cairo and Hanoi.  I'm pretty sure the horn-honking was worse in Hanoi, but there seems to be more overall noise here between the cast-off collecters' shouts, the hollering, the gas-bottle-sellers hammering on their bottles with wrenches, the horns, calls to prayers, etc.

Only another trip to Hanoi will help me be sure...
