I don't know exactly what would be causing this, but one step you could look at to start would be to enable visual bell on your xterm sessions. This would let you know which, if any, of the terminals are generating the beep, allowing you to narrow things down a bit.
from https://tldp.org/HOWTO/Visual-Bell-8.html xterm: xterm can convert each bell to either a visible or audible signal. If you use the audible bell, the settings of "xset" will apply. The bell in xterm defualts to be audible, but you can use the "-vb" command line option and the "xterm*visualBell: true" resource to turn it to a visible flash. You can toggle visible/audible signaling at run-time by using the menu invoked by control--left-mouse-button.
