Join Bill Gibson for an in-depth discussion in this video Frequency variations, part of Microphone Techniques: Essentials.
- [Narrator] It's important to keep in mind … that not all frequencies share the same … pick up pattern on the same microphone. … Typically, it's one kilohertz that defines … the overall shape of the polar pattern … but some frequencies might have omnidirectional patterns … and others might have a completely different shape. … Notice on this polar graph that there are two sides. … And each side's considered to be symmetric … across the zero degree line. … So let's look at this microphone … that essentially has a hypercardioid polar pattern … but if we look at the 16 kilohertz line … which is the dotted line on this side, … it's pretty much omnidirectional. … It doesn't really reject much from behind the microphone. … So that microphone at 16 kilohertz won't reject … much sound no matter which direction is comes from. … We can also look at the eight kilohertz line … which is this line right here. … And that's really a different shaped pick up pattern. … It's nothing like the one kilohertz line …
