While itâs possible for the umbilical cord to get wrapped around the babyâs neck or a limb, this isnât usually a cause for concern. In rare cases, the wrapped cord can become compressed, decreasing blood flow to the baby.
A hypercardioid mic is like a supercardioid on steroids; the front pickup angle is even narrower and focused, which results in greater rejection of unwanted noise and feedback. To give you an idea, the typical pickup angle on a supercardioid mic is around 115 degrees, whereas a hypercardioid can be as low as 105 degrees.
While a cardioid polar pattern is least sensitive at the rear (180 degrees off-axis), a supercardioid mic is least sensitive at 125 degrees and the hypercardioid at 110 degrees; you will need to take this into consideration when placing stage wedges.
