I just saw an interesting (debatable) discussion on a morning chat show where one of the guests (one of those experts) said that yelling at children is just as bad as smacking them.
I also scream, shout, holler, whine, moan and sometimes even foam at the mouth.
I don't yell at them.
I just yell in a very general, helpful, suggestive manner...
Eg. "WHY THE HELL AM I THE ONLY ONE WHO REMEMBERS THAT THE FLOOR IS FOR WALKING ON AND NOT AN ALL PURPOSE STORAGE FACILITY?!"
My kids don't even blink when I start. They've grown so accustomed to the sound of my voice that I'm pretty sure I hit a frequency that only dogs can hear. Which is why nobody ever listens to me. Ugh.
So yelling traumatising the deaf little darlings? Not so much in my house.
What my children fear is silence. Silence means mummy is very, very pissed off. My silence makes more noise than thunder.
And when the host asked Mister Expert if he ever yelled at his children, he looked surprised and said,
"Oh, why yes of course, I'm only human." Ugh. Why do I watch morning TV?
