user567: It is not necessarily but I wonder what would happen if monk will meditate in  "anechoic" chamber?  
The Orfield Labs room was recognized as the quietest in the world
 
If you stand in it for long enough, you start to hear your heartbeat.
A ringing in your ears becomes deafening. When you move, your bones make a grinding noise.
Eventually you lose your balance, because the absolute lack of reverberation sabotages your spatial awareness.

There will be -20db silence in the room.
  So may we know how much db of silence (internally) is produced while mediating?

So will monk be able to meditate in this room or he will suffer the effect of it? 
When we can hear heartbeat, bones grinding noise will he able to concentrate on breathing and could meditate without suffering? 

user16635: I don't think it really matters. When I meditate, sometimes I hear a car passing or a bird singing or a child laughing in the distance; sometimes I hear a scrap of music in my head, dredged up from some distant memory; sometimes I hear the sound of my breathing, or my heart beating, or the creak of a joint as my body settles. These are just sounds, of no particular importance. They come and they go. For someone unpracticed in meditation that kind of silence would be disorienting, because the outer silence exposes all of their inner noise. But meditation reaches for inner quietness.

user14789: Yes in a video ajahn brahm said that ajahn chah went into such a room. I think he said there was nothing special according to ajahn Chah.
The video was some Q&A, but you can ask for more on his forum https://bswa.org/forum/
