Yes, but that's only one benefit.

One of the common causes of furnace noises is dirty burners. Loud boom or bang sounds coming from your heating unit indicate dirty burners.

Since the air return sucks air, they are prone to getting clogged, especially if your home is particularly dusty. When vents or ducts are clogged with dust and debris, the result is reduced airflow which can cause annoying noises.
Check the flow rate of your boiler, a low water flow in the system can be a cause of the noise. (The correct flow rate can usually be found in the manual) If this is the issue, keeping it at the correct level will make the boiler function more quietly. Limescale can also be a factor that can cause a loud boiler.
