The issue at hand for this particular question is sound as qualia. That is, the perception which is independent of the physical vibrations.
All qualia ---whatever that may be--- and pereception --whatever that may be--- stem from experience ergo nervous system experience of human.
Experience precedes qualia and perception.
Humans have unique ability to conceive and communicate concepts of qualia and perception.
Other nervous system animals do not.
Truth exists beyond what you, I or other perceive to be a question.
I offered the truth of sound in post #9. You can accept, ignore or deny those specified truths as presented.
You choose ignorance. Why? Ego based mental blockage is my best guess.
Sound, specific set of vibrations/frequency of air, water or other mediume exists irrespective of any humans exist in Universe.
Concept of sound ergo invention of words to commuincate that concepts, is whole other issue, and that of course involves metaphysical-1, mind/intellect/concept accessing creatures, ergo humans.
