Sound proofing motor noises
« on: August 02, 2012, 13:16:19 »
I have just roughed in the motor and electronics for the Model Slipways Envoy. I installed steam engine and whistle/horn sounds and an ESC. Everything works as expected but the whine of the motor is so loud the sound effects are nullified.

I initially secured the motor mount to a block of wood epoxied to the hull using four screws. The vibration noises were horrendous. I experimented with various ways to cushion the motor mount from the wood block and found that using Velcro instead of screws really dampened the vibration noise. Now the main problem is the engine whine. Has anyone found a way to dampen motor whine noise. Any idea of an effective sound absorber that can be used?

I used thick rubber washers between my motor and the wood mounting block with great success. You may try using some spray foam to encapsulate part or all of the motor to dampen the whine. Be sure to monitor the temp after you do this to prevent damage.
