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.
Regardless of the system, it is perhaps enough to know that the lower the number, the more sensitive the microphone is. SPL stands for âsound pressure levelâ and is expressed in decibels (dBs). It describes the maximum volume that a mic can handle, so, in a way, it is the opposite of sensitivity.
