Hi
Listneing last night to a solo violin fill a large concert hall with the single brush of the bow against a string, it got me thinking what exactly generates the sound in an instrument ?
If we assume that energy has to be transformed into sound waves where does that energy come from in say a violin player ? the phyiscal energy expanded to draw a bow accross the strings is minimal yet it fills the hall with sound ? if this was an amplifier violin it would require many times the electrical energy to create the sound waves ?
What am i missing ? by the above logic hifi is incredibly inefficient to a level that seems like 99% inefficient.
As another thought, why do we stay with stereo and surround ? now that recording technology has progressed so far why do we use two speakers to recreate the sound of single source ? would it not be more accurate to have a single speaker playin the solo violin ?
