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.
Is it essential to use a shock mount with a microphone when recording? It is not always essential, but it does reduce the intensity of unwanted low frequency vibrations passing from the floor, through the mic stand and into the microphone. Typical vibration sources are foot tapping, kick drums on the same floor or passing traffic. Solid concrete floors tend to pose less of a problem than wooden floors, but as shock mounts are now relatively inexpensive, it makes sense to use one if you can. If a shockmount is not an option these types of low frequency vibration can often be removed with either a built in high pass filter, or by manually inserting a 80Hz, 24dB/octave filter into the mic signal path.
