Day One-Hundred and Thirty- Three: Fact

I took an acoustics class back in college. Most of the information has slipped my mind, but one given fact resounds  over and over again because my life is now in context with it. Here is your science lesson for the day:

Sounds travels in waves. The amount of waves per second a sounds passes you is called the frequency. The unit of measurement is hertz. A higher frequency will have shorter wave lengths meaning a larger amount of waves will pass per second. We generally are able to hear frequencies ranging from 20-1700 hertz. Men have a harder time hearing higher frequencies, especially when they get older. Ever heard an old guy say "What was that little girl?" The high frequencies literally do not pierce their drums anymore. A baby's cry is usually at a frequency of around 1600 Hz.

The meaning of this mumbo jumbo: When our husband's say they didn't hear the baby cry all night THEY PROBABLY ARE TELLING THE TRUTH. It's true. Also, that very frequency for a woman is similar to an overtone. It is piercing to us.

Jace is overcoming his handicap more and more. There are nights that I only have to wait five seconds longer for him to pop out of bed. He's amazing.

He babysat her for a little while today. He may not be as good as I at waking up with her, but he is certainly good at going to sleep with her.
