why oh why has nobody invented a silent hoover yet? I hate that noise! That constant drone. Its torture, and destorys the very fabric of suburban living when all you can hear in the afternoon is a hidieous noise. why are hoovers so loud? Why has no one invented a way to suppress the noise?
amazing isnt it? they can silence a pistol, but heavens forbid they silence a hoover!!!
You can indeed silence a pistol:
......, a silencer will silence a pistol caliber shot completely. A silenced pistol makes no sound at all except for the mechanical noise of the hammer falling and the action cycling.
My eldest lad, used to go to sleep to the sound of the hoover, strange hoovering at eleven at night, anyway wish they would make a silent washing machine, mines sounds like is going to take off!!!!
I suppose its just like having a requirement for a jet engine. Much of the power would be lost in trying to silence it.
In fact there are silencers available. Bose earphones have a noise cancelling device fitted which takes the incoming noise and produces a sound wave of the opposite polarity adds it to the incoming noise and so cancels the offending nuisance. I believe there is a small deteriation in the music heard though.
