A Display Technique for Evaluating the Disturbance of Microphone Response Patterns

Document Thumbnail

The manufacturers of microphones pay considerable attention to the response curves and polar patterns of their products. However the addition of any mounting clips, suspension systems or windshielding devices will negate much of it. Understanding the deterioration is assisted by being able to visualize it clearly. This paper describes a display technique that can be associated with conventional measurement systems and shows both response and polar pattern on a single plot in a manner that is easy to interpret. It also shows how this can be extended to display the effect of individual elements of a microphone accessory in an unambiguous graphical fashion. The paper illustrates several typical examples of pattern disturbance and how their effects can be explained.:
