Do You Need to Have a Spasm Outbreak for Tympanometer to Detect Myoclonus?

I'm thinking of asking my otoneurologist to do this (even though I know from the forum that it's bad for your tinnitus).

The thing is, I have been having spasms in my ears, or at least it feels like spasms. I think I'd want this examined, and hopefully I don't have myoclonus.

I want to ask, do you need to be have a spasm outbreak for the tympanometer to detect this or not?

Thank you.
