Aircraft often use 400Hz AC power systems. Not sure about helicopters. Often this 400hz noise will get into the radio and cause the low background hum.
Could just be engine noise, too.

400Hz is in the audible range.

Sounds like echo or maybe a digital radio that was set up poorly. If it's digital, it takes some experience to set up the audio side so it sounds good. A lot of times the techs just program the radio and leave it at that. End users get used to the awful sound.
