So many women are afraid of being noisy in birth. You would not believe the number of women I have spoken to who are afraid of making noise, vocalizing, etc... during labor and birth.
I believe it is a biproduct of our culture. Women, a few years ago, were taught to be seen and not heard - this belief is still prevalent in some subcultures of Americana. And, more recently, women are 'supposed to be' poised, confident, and in control. Regardless if you are of the 'seen and not heard' camp or the 'poised, confident, and in control' group, there is little room for noisy birthing there.
One of the simplest 'tricks' in my bag is to simply make noise. Women who seem to be doing so well with labor, then suddenly blurt out that they can't go on, they need some help, they need an epidural - those women I immediately encourage to make some NOISE.
I am not saying that every woman needs to be a noisy birther, but there is great evidence to suggest the correlation between the vocal chords and the cervix . And, any of us who are physically active out there can attest to the stress relieving, and thus, pain relieving qualities of simply making noise.
Now, not ANY noise is good noise - it has to be a certain type of noise. It doesn't matter if it is loud or quiet, but it does matter what form it takes. Positive noise includes
Some examples of these noises are vibrating hums (when the jaw is relaxed), horse lips (per Ina May Gaskin), ooohs, aaahs, uuuuhs, naughs, and even singing.
Singing is an amazing vocal labor relaxation technique. It helps to control your breathing, encourages deep breathing, and keeps your vocal chords, jaw, and body relaxed. It also works through distraction from contractions and focus on resonation. And, just for viewing pleasure
