Brüel & Kjær measurement microphones are precision instruments of the highest quality. While the design of a microphone may appear to be quite simple, the production process requires the utmost attention and control to ensure performance and stability. Our pioneering experience in acoustic measurement techniques, rigorous testing, and quality control guarantees that you are provided with measurement microphones that set the standard to which others are compared.

SELECTING THE RIGHT MICROPHONE

Selecting the best microphone for a given application can seem to be an overwhelming task due to the many different types to choose from.

Firstly, condenser microphones are either externally polarized or prepolarized. They come in different sizes: 1‐inch, 1/2‐inch, 1/4‐inch, or 1/8‐inch and are optimized for either free‐, pressure‐, or diffuse‐field. Microphones that do not directly match one of these classes are denoted as "Special Microphones".

Not all positions in the matrix correspond to a type of number, for example, 1-inch microphones are normally externally polarized, since they were introduced before prepolarized microphones could be produced with sufficient stability.

1/8‐inch microphones are pressure types. Due to their small size, the free‐field and pressure response are approximately the same up to quite high frequencies (for example, the free‐field correction is less than 1 dB at 15 kHz).
