Flute Acoustics Essay -- acoustic sound

A flute blows a rapid jet of blood across the embouchure hole. The pressure inside the players mouth is above atmospherical (usually 1kpa just enough to support a 10cm height difference in a water manometer). (http//newt.phys.unsw.edu.au/ unison/) The work done to accelerate the sort in this jet is the source of power input to instrument.Sound requires an vacillate motion or logical argument flow. In the flute, the ship jet, and the resonance in the air in instrument produces an oscillating component of the flow. As the air starts to vibrate some of the energy (sound ) is radiated out the ends and through any clean holes. Most of the energy is lost as a sort of abrasion (viscous loss) with the walls. The pitch or note can be altered actually slightly by breath and lip adjustment, but if changed completely the distance of the air must change.This is why the holes in the flute are utilize to remove the constriction of the air at that particular point. The resonance of the a ir column in the flute mostly determines the playing frequency which is the pitch. (http//newt.phys.unsw.edu.au/music/) Since the...
