I don't know if this might be of use, but below is a link to a tinnitus society. Once there, you'll find another link which enables you to hear the many, varied types of sounds that constitute tinnitus. Many have a clacking-type sound but right at the very end are a few that sound rather like the one I'm hearing.
Although it's similar, I think I'll check out the cat deterrent boxes too

did you get any dental work around the same time the noise started?
