Quiet The Whine.

Name someone that likes the sound of servos... that's right, no one.

So what does anyone know about quietening the sound from servos? Would love to hear any ideas that anyone has.

One idea I was thinking was to put all the servo's for a robot into one box, and connect their moving energy to a flexible cable that passes through a hollow tube to where you want the work done. That way, perhaps the box could be coated with muffling material.

Looking to hear if anyone else has any thoughts on siliencing techniques.

Deaden the air in the servo's..

Using RC boats alot ..I strip down and pack my servo's with Dielectric Grease. Funny the easiest way to keep them dry was to get them wet..

It quieted the servo however..a few decibels..

if you put a rubber mount between the body and the servo you will reduce the transfer of sound from the servos to the body witch acts like a sound box (guitar body) amplifying the sound large flat plates are the worst offenders applying a rubberized paint or rubber seat to these bad zones can reduce sound transfer

Moment = Sound

when sound moves from one thing IE air to a solid object or from one solid object to another it loses energy if the objects have different density the effect is grater  

i like the sound of servos , they sound like robots .:)

While centralizing the servos might make noise supression more simple, it also vastly complicates the mechanical design. I think kingart3 has a better approach. 

I'd also research the world of animatronics. I bet they have some ideas around this topic.

Surrounding the body of the servo with foam might quiet the noise.  Heat retention could be a problem, I suppose it would depend on how hard the servo is working.

A lot of the noise comes from the gears.

I had a chance to play with a good quality digital servo that had aluminium gears. It was much smoother and quieter than a standard hobby servo.
