We studied the Particle Theory of Light in Physics but nothing related to sound.
hm.

Last year I had to take a course entitled "Bioacoustics of Hearing".
At first I thought, "Hey! There talking about dB's and SPL's and stuff I could really dig this".
I got lost after the first paragraph explaining what decibels were. Mind you this was the first course I took since '96.
My studies never required knowing exactly how sound propagates. It more focused on how we hear. There were some interesting (but thick) reads on how sound travels.
How we hear is actualy quite misunderstood.

also 3 db gain, is double the acoustic energy. a 10 db increase is double the loudness to the human ear so to speak.

now its been a really long ime since I was a complete theory geek..maybe someone can refresh my memory... at which level will sound waves actually become visible? if I remember correctly ..is it not aprox 190dB? as you are speaking of it
