Let's define "SOUND".
Sound Wave travels through the air and enters our ears, which is converted to electrical impulses and is sent to the BRAIN.
We're not robots, so our brains do not interpret the sound as one's and zero's.
If your brain cannot distinguish between 101dB vs 100dB, then the SOUND will be the same.
SOUND is what our brains actually hear/perceive/interpret/distinguish, not the difference in measured numbers.
