Brüel & Kjær matched pairs are easily identified by the small 'screw studs' on their diaphragm protection grid. These are used to secure the microphone spacer which is part of the sound intensity probe assembly. The two microphones in the matched pair are additionally labeled Part 1 and Part 2 respectively. The two parts are uniquely matched and should always be kept together.
There are both 1/2" and 1/4" matched microphones. 1/2" matched pairs are the most popular choice for general sound intensity measurements. 1/4" matched pairs are selected for high-frequency sound intensity measurements and use in side-by-side probe assemblies. The side-by-side arrangement enables the microphones to be used much nearer to a source than the more common and more acoustically ideal face-to-face probe assembly.
