A DISPLAY TECHNIQUE FOR EVALUATING THE DISTURBANCE OF MICROPHONE RESPONSE PATTERNS

摘要

The manufacturers of microphones pay considerable attention to the response curves and polar patternsof their products. However the addition of any mounting clips, suspension systems or windshielding devices willnegate much of this. Understanding the deterioration is assisted by being able to visualise it clearly.This paper describes a display technique that can be associated with conventional measurement systems and showsboth response and polar pattern on a single plot in a manner that is easy to interpret. It also shows how this can beextended to display the effect of individual elements of a microphone accessory in an unambiguous graphicalfashion. The paper demonstrates several typical examples of pattern disturbance and how their effects can beexplained.
