bzzbzzzzz* ** - dibeh -

If we substitute * for . and take the buzzes as distorted . and - (based on length), we get:
.-. .. - dibeh -
r i t dibeh t

But I can’t see where else that could go – it’s still gibberish, and doesn’t cipher or anagram to anything meaningful either. So I’m not sure if morse code is the right way to look at it, but I feel the punctuation is definitely significant in some way.

Edit: bzzbzzzzz and na-zz-tso-zz are both 9 characters. Perhaps the full message is meant to be na-zz-tso-zz* ** - dibeh -?
