I'm embarrassed to say I spent the first week or two with my pulsatile tinnitus fascinated by how rhythmically the wind was gushing through the trees outside my bedroom window. At some point I must have rolled over, the whooshing noise switching sides along with my left ear, and realised the noise was not coming from outside at all.
About 6 months after onset it disappeared as quickly and mysteriously as it first appeared.
Glad to hear yours disappeared! From what I understand, the pulsatile variety is usually linked to something physical in the ear, unlike regular tinnitus. It's definitely the case for me, as one of the most interesting things about mine is that I can make the sound completely disappear by pressing on my carotid artery (e.g. if I were to take my pulse). That little detail helped soothe the anxiety by realizing that it's just something funky in the blood vessels around my ear.
