Hi,
I guess i didnt want it to get too complicated, and also reversible just in case what i end up doing doesnt work good enough and has to be removed. For example, i can fill the interior with hot glue but if the hot glue vibrates too much it will still sound, and how loud it will be is hard to predict. Perhaps what i should do is experiment with another piezo not the oven piezo and see if i could get that to shut up. IF hot glue works, i just might do that. If not, i could always peek it off because i'll have the piezo out where it can be played around with no problem. The one in the over is in a confined area, maybe i couldnt even get the hot glue gun nozzle to squirt into the other side, the open side. The side on the right has a small hole, the side on the left is completely open, but the side on the left is hard to get too or even view without a small inspection mirror.
