Noise measurement in ball and roller bearings - ICT
In other words, below 1000 Hz is considered to be vibration and above 1000 Hz is sound or noise. Race noise is the most basic sound in rolling bearings. It is generated in all bearings and is a smooth and continuous sound: its magnitude is used to assess bearing quality. The race noise is around 1/100 of the magnitude of normal conversation and

A Guide to Bearing Noise and Vibration
A low noise/vibration rating is achieved by paying particular attention to the surface finish of the raceways and balls, the roundness of the rings and balls and correct cage design. Finely filtered low noise greases can also be used. These contain fewer, smaller solid particles which generate noise when they pass between the balls and raceway.
