Pat Suwonpanich has made a comment on hearing and sound as a mental phenomenon leading to questions of conscious mind that I think is worth pondering by one and all, so let us headline (with slight edits):
>>For those who wanna read less-technical article on hearing, I have tried to write my own article as shown below. Hope it will be useful for many of us.
Whenever we hear beautiful music or any other interesting sounds, we should realize that the ability to hear is so special that no known set of nature’s laws can explain it !
Most of us tend to think that we hear sounds because there are various sounds around us. In reality, if there were no human/animals that can hear, there would be no sound, just air vibration. 
Without brains of human and animals to interpret the air vibration into sounds that we experience, there is no sound at all, only soundless air vibration. The entire universe is in fact ‘silent’. Sound only really exists in human’s and animals’ minds. 
Ability to hear is one of our senses. Most importantly, it is a part of consciousness. But the big problem is, scientists know very little about mechanisms of consciousness. Although many scientists are materialists, no scientists know how matter generates consciousness.  In the case of hearing, no scientists know how to make ‘sound’ from air vibration.
The origin and mechanisms of consciousness are very “special” because no known set of nature’s laws suggest that matter can generate consciousness. It is so special that many scientists admitted that, “questions of consciousness may be beyond the bounds of science” , “We just don’t know how we should think about ‘being’ and how ‘mind’ fits into nature.” 
Consequently, even the world’s top scientists can’t make AI or robots that have consciousness.  No scientists can make AI or robots that can hear sounds like human or animals. 
set of Ultimately, the fact that ‘no known nature’s laws suggest that matter can generate consciousness’ has a very important implication. Without nature’s laws for consciousness to emerge from matter, consciousness certainly can’t arise by evolution !
From air vibration which has no sound, the Creator beautifully designed what each sound should sound like. Inside brains, the Creator put the special program that can interpret each frequency pattern of air vibration into each sound, thus giving us the sound experience.
This amazing creation results in hearing ability which is very useful for us to observe surrounding through sounds, enjoy music, communicate in language, etc.
As said at the beginning of the article, whenever we hear beautiful music or any other interesting sounds, we should realize that the ability to hear sounds is so special that no known nature’s laws can explain it. Without the nature’s laws for consciousness to emerge from matter, consciousness certainly cannot arise by evolution !
