14.Honk!Squeak!
What is that?If you're going through puberty(青春期),it could be your voice.Both boys and girls experience voice changes as they grow older,but girls'voices get only a little deeper.A boy's voice,on the other hand,may change quite a bit-from sounding like a little kid to sounding like somebody's dad!
How does this happen?The larynx,your voice box,actually gets bigger during puberty.One of its jobs is to let you talk,sing,hum,yell,laugh,and make all sorts of noises.
When a boy reaches puberty,his body begins making lots of testosterone(睪丸激素),which causes his larynx to grow and his vocal cords(聲帶) to get longer and thicker.
Before puberty,your larynx is pretty small and your vocal cords are kind of small and thin.That's why your voice is higher than an adult's.As you go through puberty,the larynx changes.As your body adjusts to this changing equipment,your voice may"crack"or"break".But this process lasts only a few months.
Not only do older guys and men sound different from boys,but you can also see the difference in their necks.When the larynx grows bigger,part of it sticks out inside the neck.You can see it at the front of the throat.This is known as the Adam's apple.For girls,the larynx also grows bigger but not as much as in boys,so you can't see it through a girl's skin.
Everyone's timetable is different,so some kids'voices might start to change earlier and some might start a little later.Some voices might drop gradually,while others might drop quickly.
If this hasn't happened to you yet,don't worry.And if you're going through this now,try not to stress too much about the funny noises you make.It can help to talk to a parent,or a friend who's already gone through the voice change.Before you know it,your voice will sound clear,strong,and more grown-up!
