Eli5…Walking on the moon…

I understand that the moon doesn’t have an atmosphere and you wouldn’t hear any sound…but is there an atmosphere in your spacesuit? Like the quietest room on the world do you hear your body? Blood rushing through your ears, etc.

You wouldn’t hear any sound that originates externally to the suit unless its strong enough to vibrate the ground and so get transferred to you that way,

Any vibration originating from inside the suit or in some way mechanically attached to you (ie, sitting in the lunar rover seat) you would be able to hear.

No, you’d mostly hear the rush of coolant as the thermal control system in the suits tries to keep your body from boiling in the sun and freezing in the shade

Yes, you would hear sounds from inside of your spacesuit, like your own breathing. The suits are pressurised and filled with breathable air.

Incidentally, the Moon does have an atmosphere, it’s just very thin.
