It wasn't until I moved into a house under the final approach (for the least commonly used runway) that I realised this is untrue. On a calm night with no wind, the wake turbulence makes a significant amount of nose that lasts for several min after the plane passes. Normally wind noise drowns it out, but due to the longer duration the total amount of noise is equal-to or greater than the engine noise.
