Helicopters are loud because the blades cross over the airframe and are powered by turbines. An electric multicopter based design could have significantly lower noise levels.

If going by the noise emitted by your average consumer drone, and scaling it up, I think the opposite is probably true - it would be crazy loud.

Consumer drones aren't really aiming for quiet though. My racing drones are very buzzy since the small 3-5in props are fast spinning to have quick reaction time. My heavy lift photography drone with its slow 12in props (aiming for efficiency) is way larger and much quieter.

Few consumer level drones make any effort at noise reduction. Blade and shroud design can significantly impact noise production.
