Trying to Find Quiet DC Motors

I am looking for a motor and was wondering if someone could suggest or help me find which would be best suited for my project. I dont know too much about motors so any help would be greatly appreciated! The main two requirements are size and noise level. I am currently using a very small,[ cheap geared motor (6volt DC 140 rpm, 0.3kg.cm torque, 24.2 x12 x10 mm) and an equally small [motor driver. I am basically trying to push a small pendulum back and fourth. This motor creates a fair amount of noise (even after adding extra grease) and so I am looking for a quieter motor at around the same size and torque (more torque would also work). Again, any help would be greatly appreciated on this.

It’s a bit bigger and needs 24 volts to get the full RPM but [ROB-15277 is pretty quiet.](https://www.sparkfun.com/products/15277)
