I read all three of your posts.  

Do the doctors say whether or not they have actually heard the pulsing
noise you hear with any instruments?

Have you been given any medications to help you sleep and/or cope with
the stress of the tinnitus?

PULSATILE TINNITUS (PT)
Most important! See your doctor first.

If no cause can be found after various tests have been performed,
then it is most likely due to MUSCLE TENSION.
Please see a massage therapist - trusted chiropractor,
physiotherapist, aroma therapist etc.
See if there is tension in your body. Ask questions of the therapist.
Where is the tension?
What can I do about it etc?

Then ask your self: What am I doing during the day that could be
causing this?
Do you clamp a phone in your neck? - get a headset.
Are you sitting badly? - improve your posture.
Is your computer positioned correctly?

Is the monitor at eye level - no peering up or down.
Is the keyboard roughly at your waist level?
Is your chair comfortable? no slouching.

Do you drive a lot? see travel tips

3. A relaxation exercise by an internet ENT, Dr Murray Grossan:

I had a brief episode some years ago. I had become aware of muscular
tension by this time, so I got rid of it as soon as I could.
I had been a passenger in a a car on a long trip. After driving for 2
whole days I began to feel as if an iron band had grown around my
chest. When I bent down to pick something up off the floor the PT
kicked in.
My seating position had not been what it normally is when I am the
driver. I usually have a cushion in my back and sit up straight.
Because I was a passenger I thought this was not so important. But I
was wrong.
I put the cushion back and sat upright for the next week. The PT went.
