Yes, but no sound waves in the air are involved. It is entirely in your head.

I believe it is quite distressing when it is serious and frequent. I get it very slightly and rarely. I never notice when it stops, just that at some point I realise it has stopped.

I get it pretty much every day but most of the time I don't really notice it. Worst is lying in bed trying to get to sleep. If I have been in a loud environment then I can have it even whilst watching TV. It is not debilitating like it is for some but definitely can be annoying.

Not always true:

In reference to en.wikipedia.org/wiki/Tinnitus#Types:

In rare cases, tinnitus can be heard by someone else using a stethoscope. Even more rarely, in some cases it can be measured as a spontaneous otoacoustic emission (SOAE) in the ear canal.

Weird.

That's interesting BIll, thanks Though I don't think it really relates to the original question about the falling tree.

Very interesting is the part about possible occasional cause by prescription drugs either during use or on withdrawal.

This thread has enjoyed quite a few brief off-topic excursions, I figured one more wouldn't hurt

Agreed, but .

PS: An even bigger "drift" in TTTS at the moment.

When I used to use my mobile phone in my (steel) cabin when passing, say Cape Town, I could always hear/feel the zip-zip of the GSM signal. Solved with a magnetic car aerial position near a window.

Also, during a SLT procedure (Selective Laser Trabeculoplasty) I could hear clicks for each firing of the laser, although the ophthalmologist could not - so he said.

Cheers!

Apologies for Off Topic,

@Ancient_Mariner ,
I've also had the SLC treatment, and yes during one of the treatments I could hear clicks.
I'm sure the professionals didn't believe me when I mentioned it later.
Anyway, I hope the treatment has worked for you, it's not always 100% successful.

It helped initially, but a few years on and my IOPs have just jumped up.

I was on drops, but found that the preservative caused upset and on the suggestion of the ophthalmologist I ceased using them for a couple of weeks, found that they were not actually doing anything other than being painful to use.

Has the SLT been successful for you?

I am booked in next week, so will see what my options are.

Cheers!
