That’s called pulsatile tinnitus. I used to hear silence, then after a jaw injury I started hearing my pulse and eventually ringing.
But no normally you wouldn’t.
If you or anyone reading this any possibility of cardiac issues (high blood pressure, clogged arteries), it would be worth mentioning at your next checkup.
Mine was pretty clearly linked to an injury that eventually caused other tinnitus so I assumed the causes were similar. Note that per the link below pulsatile tinnitus can be quite benign, but is does have some causes worth excluding.
And why is that, since the causes are so varied and often specific?

makes pricey but very effective and comfortable mouthpieces for wearing at night while sleeping and/or during the day. They look exactly like the ones some NFL players use. I love mine. If I'd used one before discovering them three years ago at age 69, I wouldn't now be getting a mouthful of astronomically expensive ($6k apiece for extraction/bone graft/Ti screw placement/tooth) dental implants.

I clench, didn’t know about it for years and so didn’t have a mouth guard. Have a bunch of cracks in my molars now. My dentist always used to say these sort of cracks were the biggest problem in adult dentistry.
The solution is to get a mouth guard. Bottom guard type seems preferable. This will prevent future cracks, protect your gums, and protect the jaw joint. Unfortunately it doesn’t solve the problem, but no one seems to have figured that out yet.
You can also use a Sleepguard device to measure clenching activity. A bit clunky, but it has been very useful for me in figuring out triggers for worse clenching and confirming I do it.
My clenching started after that same jaw injury, I think. Or wisdom teeth extraction.
Someone else recommended off the shelf guards. I would suggest a custom splint from a dentist. If the splint is misaligned you can clench unevenly and cause jaw structure changes.
