A woman in China is coping with a rare disorder . . . she cannot hear men's voices! One night she felt nauseous, had ringing in her ears and finally was able to drift off to sleep. When she woke up, she could not hear deeper sounds - men's voices included. It's a condition called Reverse Slope Hearing Loss. It keeps you from hearing lower sound frequencies. So, what caused it? Her doctor says stress and fatigue and genetics. They say she will recover.
