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.
The audio spectrum is the audible frequency range at which humans can hear. The range spans from 20 Hz to 20,000 Hz and can be effectively broken down into seven different frequency bands, with each having a different impact on the total sound.idrange: 500 Hz to 2 kHz. The midrange determines how prominent an instrument is in the mix. Boosting around 1000 Hz can give instruments a horn like quality. Excess output at this range can sound tinny and may cause ear fatigue.
