Background: vacuum cleaners are annoyingly loud as anything. I suppose it can’t be very helped because of the necessary motor and perhaps suction sound.
Useful invention: creation of a small-space-encompassing bubble that acts as a complete muffler of any sound within.
Much room for abuse: gun toters, .....and i had a few other scenarios of abuse of silence, but now i can’t think of others…. oh, right.. baby kidnappers.. oh, hey, rapists… bad people in general. not being able to hear cars sneak up on you..
well, anyway, i’d like to put one on every motorbike (motorbikers who choose to have a noisy engine/muffler for the sake of it are thoroughly obnoxious to me. i’m not fundamentally against motorcycles/motorcyclists, but I very much think they should be conscious of their (noise) pollution and do what they can to keep that clean. Same with cars.
Anyway, a Quiet bubble would be good. Especially if oxygen can still flow through.. The idea would be to figure out what sound travels on and what stifles sound, and artificially create that….... i think it’s doable. i just don’t think ….it’s doable yet. shrug the end.
