I have been a reader of this forum for a while now, and now decided to post on this subject.
Since +/- 10 days I have been a daily supplement that includes 500mg NMN.
I plan to take it for 2 months and report my findings here.
Background:
I am a 42 year old male. I have developed tinitus I around 6-7 years ago, at a very low level. I have no clear indication why, but probably due to hearing damage (i have visited many concerts when I was younger). About 5 years ago I suffered from acute hyperacusis due to an ear infection, which resulted in heavily distorted hearing at my right ear. (and also slight Meniere's disease) An audiogram at the doctor showed hearing damage in my right ear around the 1k Hz range. Whether or not this damage was pre-existing was impossible to tell. The doctors sent me home and said nothing else he could do.
Luckily the hyperacusis has gone away in the +/- 6 months after that episode, but it was replaced with increased tinnitus.
The last two years have been quite stressfull for me after the passing of a loved one, and I have noticed my tinnitus has increased over these years. In these years I have been drinking moderately but daily (2 units a day, sometimes more) and I have noticed I am clenching my jaws regularly (due to the stress).
I currently (subjectively) class my tinnitus as a 6. It is a high pitched tone.
As an example, I need to increase the volume of my TV to be able follow what is being said on the news over my tinnitus pitch.
Regiment:
Starting this January I decided "enough is enough" and I stopped drinking altogether. I also started to look for a good supplement that could increase my general health. This supplement I started taking about 10 days ago. I take it daily during my lunch, as I felt slighly nauseous taking it before breakfast.
It was only recently that I noticed this thread, and the possible positive effects of NMN on hearing/tinnitus.
So I decided to report on my findings on the effects in this thread.
I will report today. At the 30 days mark, 45 days mark and the 60 days mark.
Unfortunately I don't have a 0 day audiogram, as I only thought about doing all of on this forum yesterday.
In addition I am going to check my hearing through a free tool online and post the audiograms here. I will use the exact same setup and settings each time I test. I would like to make a clear note that the results in the screencap seem to be a couple Db worse across the whole hearing range (due to lack of calibration) than the test I have done with the doctor 5 years ago.
However, the test is intended to track changes over this period. And if there are any changes, the test will reflect that. Hopefully the results will be helpful to others.

Audiogram
As you can see, there is hearing damage especially in the right ear around the 1k Hz.
