Hi @adr, it definitely sounds like pulsatile tinnitus. I did move your post to this one: Thumping/drumming in one ear

so you can connect with other people who have been diagnosed. This kind of tinnitus is often the first clue that you have something else going on that needs to be treated. Your treatment plan will depend on what’s causing your tinnitus. Have you considered a white noise maker to drown out the sound while you wait for your appointment?
