Discharge is your bodies natural way of cleaning itself. If you use douches, DON'T. They are really bad and cause your bodies natural PH to be washed away which can cause the bad stuff like the bacteria that cause yeast infections to take over......not fun.
The commonly stated range of human hearing is 20 Hz to 20 kHz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz. Humans are most sensitive to (i.e. able to discern at lowest intensity) frequencies between 2,000 and 5,000 Hz.
Humans can hear sounds at frequencies from about 20 Hz to 20,000 Hz, though we hear sounds best from 1,000 Hz to 5,000 Hz, where human speech is centered. Hearing loss may reduce the range of frequencies a person can hear.
