Yes, it would if you were using a non-selective receiver like a membrane of foil or whatever was used in the lab tests on VLF (which I presume is the model of how human eyeglasses, teeth, etc. would be picking up these VLF). But, of course we all use radios to tune specific frequencies, so WWVB comes in loud and clear, even if a much stronger nearby frequency signal were present.
