I have the same thing @Acalaa
It is my personal observation but not only, because many of my meditative companions see/hear/feel it the same way, that few things are intercorrelated:
First of all, experience of piti in the body is often associated with arising of the “high pitched sound” or perhaps something like sound of crickets singing at night. It is interesting to note that people who do OOBE’s also hear high pitched sound, so it is clearly not just “tinnitus” thing.
Experience of piti in body is sometimes related to seeing movement in visual field even with eyes closed.
The stronger the piti or the visual movement, usually the stronger the “sound of silence”.
I wonder if what people call “tinnitus” is in fact a disorder, or if it is just sound of random bursts of energy flow through the subtle body? Energy that buddhists call piti, and hindu call prana. The fact that buddhist practitioners who familiarise themselves throught meditation with so called “tinnitus”, find it usually pleasant and calming, leads me to conclusion/prediction that this tinnitus is not a disorder in itself, but some people are going a little nuts, because in their minds there are sounds that they cannot control and interpret it negatively.
I personally wonder if this energy (piti/prana) can be heard as high pitched sound/other inner sounds, and personally I believe this is the case.
There is ancient yogic practice called “Nada yoga” which is about hearing this sound, and some yogis believes that hearing it can lead to oneness with Brahman. Source: https://www.amazon.com/Practice-Nada-Yoga-Meditation-Sacred-ebook/dp/B00HDGKYWI
Also Pythagoreans were mystics, who was speaking about “music of the spheres” I wonder if they perhaps didn’t mean the same thing.
Of course it is meditation object rarely used in buddhist circles, but as mentioned, Ajahn Sumedho wrote about it, chapter 12 is about Sound of Silence:
Anyway, my interpretation of word “kaya” is such that it doens’t relate only to physical body, but also subtler perceptions of the subtle body. And if subtle body can be perceived with different “sense” than only tacticle sensations, then I think perceving this sound can be taken as “kaya”, just as seeing forms that are also felt in deeper states can be taken as “kaya” or “rupa”.
And so we can breathe in stilling “bodily formation”, which this sound can be extension of. I think on deeper levels of the mind there is hardly distincion between the senses, and they more or less merge into oneness. And I think this “sound of silence” is part of it, just heard on a level of perception that still divides this energy into particular different sense doors.
That is my take on it, but I know I’m in a minority.
I’m aware thou that we have unique minds, so it is hard to say if what is true for my mind or some other people, will be true for everyone else. And suttas I think doesn’t deal with this subject directly in any way. That is why I also this thread belongs to watercooler section
With metta and may all tinnitus in the world be calming support on the path and in life Imo it is great samatha object If it calms you down, it does the function of samatha. I hope everyone will be friends and at peace with their tinnitus Perhaps it wil lead them to Brahman or even to jhanas
