CAN THE ANNOYING BUZZ OF A DRONE BE SILENCED?

• Its fair to say that one of the most exciting
  and innovative inventions to have come out of the
  modern era are drones. More and more of them are
  being bought and flown every single year, and as
  technology advances, their capabilities seem to
  know no bounds. With new ways of flying them,
  ultra HD cameras and batteries with ever
  increasing lifespans, todays unmanned aerial
  vehicles are truly incredible. However, some of
  them (if not most of them), are noisy and that
  annoying buzz can be hard to ignore others in
  the vicinity when theyre being flown might even
  be driven to register a complaint. So, can
  anything be done to eliminate or reduce that
  annoying buzz from the rotors, engines and
  electronic parts?

• Silent drones do they exist?
• The straightforward answer is no, they do not
  exist. For as long as drones have moving parts
  that keep them in the air, they will always make
  a certain amount of noise. The vibrations from
  the moving parts will always be audible, however,
  many makers are working hard to design and make
  drones that are quieter than their predecessors.
• What are the noise levels of a drone?
• In flight, a drone registers at around 75 to 80
  decibels and a quiet one is usually considered to
  be one that registers at 65 to 70 decibels when
  flown 3 to five feet from the pilot.

• Stealth drones used by the military
• Although most of the details are kept secret by
  the military, it is widely believed that they are
  using stealth drones which may achieve true
  silence or can at least be described as inaudible
  when in flight. Whether these will ever be made
  available for public use or purchase is anyones
  guess.
• Why would a silent drone be so useful?
• Aside from the fact that the noise of a drone in
  flight is annoying, it can also drown out all the
  sound on a video recording, making them virtually
  unusable for audible recordings. Even if you only
  want to record a video for visual purposes, the
  background noise of the drone will be very
  distracting.

• A silent drone would also be useful when used for
  surveillance purposes, since it wouldnt give the
  location away when monitoring someone.
• Key features of a quiet drone
• A good, silent or very quiet, drone, needs a
  sturdy, thick body that can cover all the
  internal features and mechanisms such as the
  motor and battery areas that can create a lot
  of noise and give less space for the annoying
  sounds to be omitted from. Vibrations also need
  to be minimised, and this can only be achieved by
  a drone with good physical features that dampen
  those vibrations.

• Stores may not be selling fully silent drones
  anytime soon, but with the way technology is
  advancing, and with more money being invested in
  the entire drone industry, it wont be long
  before something much quieter is available for
  the general public to buy.
