you know when theyre hiding you cant hear them at all
No such thing as a mute button. Sorry.
Apaches are somewhat quiter than the Cobra is since it has four smaller main rotor blades that the two enormous ones fitted to the Cobra.
If the aircraft is facing you, it’s likely that the tail rotor, which is very noisy, can’t be heard, thereby lessening the amount of noise you hear. But, in all my experience, unless there is something between you and the aircraft blocking the noise, they are thunderous noise makers.
