Pulsatile tinnitus is a rare type of tinnitus that causes a rhythmic sound in time with your heartbeat. It can sound like a whooshing,
throbbing, or thumping in one or both ears. This is often caused by disorders or
malformations in the blood vessels and arteries, especially those near the ears. These abnormalities or disorders - including aneurysms and arteriovenous malformations - can cause a change in the blood flow through the affected blood vessels.
Rectangular and Oval shapes formed the architecture of the heartbeat and connecting neural networks which in this case is interpreted in linear forms.
This is not only an experimental process of mine, but rather a message to everyone going through one form of tinnitus or the other. The brain will tend to adapt to it. But you are never alone.
