Ribbon microphones are very fragile and can be damaged easily. Therefore, they are almost limited to in-studio controlled applications where treble response is not an essential requirement. | Ribbon microphones are very fragile and can be damaged easily.

- | * The cardioid polar pattern. The cardioid polar pattern is the most common of the directional polar patterns. Its name originates from its polar shape characteristics that resemble a heart. Furthermore, | + | |
- | * The bidirectional polar pattern. This polar pattern is also known as a figure-of-eight directionality pattern. As their name states, such devices are capable of registering sound coming from both ends of the diaphragm. The microphones described by this type of pattern can produce highly realistic sound duplication because of their ability to record more of the natural ambience of the recording space. | + | * The bidirectional polar pattern.

- | * The omnidirectional polar pattern. The omnidirectional polar patterns are able to record sound incoming from all sides in a perfect sphere. This results in increased movement freedom as the angle position of the source will not affect the overall sound of the recording. | + | * The omnidirectional polar pattern.

The frequency response of a microphone, as its name states, describes the frequency range of sound that a microphone can correctly reproduce. The signature sound of such devices is mostly defined by their frequency response, which is typically represented by a graphical response curve.
