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.
In 1956, thanks to the development of smaller capacitors, Neumann was able to reduce the length of the mic by almost three inches. The capsule ï¬nish was also changed from chrome to matte, matching the rest of the microphone. The U 48, a cardioid/bi-directional version, was marketed in 1956.
