Normally, XpdfViewer will emit a beep on various error conditions
(attempting to go to the previous page from page one, attempting to go
to the next page from the last page, a text find string that isn't
found, etc.). This property enables or disables beeps. The default
value is enabled.
VB:
viewer.enableBeeps = False
