Is this normal or something wrong? It's not a debilitating sound, its just annoying because it's noticeable.

It's not normal, but you didn't give enough info for a diagnosis.
Is your car stock? If any mods, what are they? Engine/electrical mods can cause interference.
Is it a stock radio? If so, base or Bose? If not, give a description of system.
Does the noise change frequency or volume with engine RPM?
Does the noise change frequency or volume when you turn the headlights on?
What exactly do you mean by "mute the sound"? Turning the volume down?
