If a woman calls out in forest of boys, will anyone hear her?

No, because the definition of sound is "something that you hear." No one is listening when the mom calls , so the mom doesn't make a sound. This answer is valid as long as no details are observed technically. And this seems to be the story of my life. 
It really amazes me that my voice can go undetected in my own home. This is the same voice that has gotten me in trouble so many times when it was heard during church or class. Or in my case sign language 101. I took this class my freshman year of college as a language credit. It was taught by a deaf instructor so as long as she wasn't looking, I thought I could talk to my friend across the room. Wow, I was wrong.
So even a deaf woman can hear me. Why can't my own sons, husband, brother, co-workers hear me?  I sometimes wonder if I have accidentally hit my mute button, a mute button I have yet to discover. When I find out, I will let you know.
I hear them. Something someone never tells you when you are pregnant is that when your child is born your hearing will be supersonic.  I believe that you acquire the hearing function from your husband and deplete him of late night hearing function.. I can hear a baby two rooms away when I'm dead asleep if they happened to mis-breathe, and I know I may have made that word up, but if you are a mom, you know exactly what I mean.
When I was in the hospital the day I had a c-section, I had a panic attack during surgery. It continued past recovery and into my hospital room. They gave me 2 ambian to calm me. I was asleep for 20 min. and my "sleep" was disturbed by my newborn, who I had known for 2 hours, crying in the nursery down the hall.
THAT is supersonic.
Unfortunately, our house has been hit with this stomach bug thing.  Because Jack has had a high fever he has been having nightmares. His cries could probably wake up our neighbors, but not my husband.  Lately, he has been hallucinating also. He was asking for a check mark last night, and seemed really upset when I couldn't produce one immediately at 3 a.m.  By the time I came to him with a juice box straw that somewhat resembled a check mark (the resourceful person I am)  he had already fallen asleep and never to ask for it again.
I also find a way to blame myself that he has gotten so sick. If only I would have breast fed him longer. If our house was cleaner, if I made him wash his hands more, or maybe I should wash my hands longer, etc.  What I do realize (and admit to feeding on) is the attention that I get.  He doesn't want anyone else. If I convince Don to go to his bedside during one of these dreams, he immediately demands mommy and won't settle for anything else.  So as much as I want to sleep, I am flattered that I am the toddler whisperer. 
Even if it is a delirious 3 year old.
As I'm writing this I'm listening to my oldest son with his piano lesson, I can also here the baby whining in the swing because he is over tired and I suspect that the two middle ones, have taken the mattresses of their beds (again) and its only a matter of time before someone screams. 
I have discovered however, that there is one way I can get there attention and that is to not say anything.  I suppose that the sound of my voice has a white noise quality that is their status quo.  But when is stops, the silence is defining.
