Supercardioid T he supercardioid is even more directional than the cardioid sensitivity pattern. This polar pattern is similar to that of our ears as we turn our head toward a sound we want to hear and try to ignore interfering sounds. Shotgun mics are a type of supercardioid mic widely used in on-location video production. Hypercardioid E ven more directional is the hypercardioid . Although this mic's narrow angle of acceptance means that off-axis sounds will be largely rejected, this also means that this type of mic has to be accurately pointed toward sound sources.
Regular adjustments have to be made if the talent moves.
Some highly directional shotgun mics are included in the hypercardioid category . The light blue arrows represent the direction the mics are pointed. A top view is shown for the bi-directional mic. The dark blue areas represent the areas of maximum sensitivity. Parabolic Mics P arabolic mics represent the most highly directional type of mic application.
