One can usually rely on the manufacturer to supply a motor that conforms to their published characteristics, and it is these data that are used in the selection process.

The noise coming from a motor is largely dependent upon the acoustics of the surroundings and the nature of whatever the motor is driving. Were it to be a car-crusher, for example, the noise of the motor would be largely swamped by that coming from the crushing equipment.
