Microphone Cartridges
Brüel & Kjær microphone cartridges are suited for a wide range of measurement applications. Four types of microphones define the sound field and adaptability for specific environments, industries, and measurement conditions, and are referred to as free-field, pressure-field, diffuse-field, and special microphones. B&K microphone cartridges are supplied in 1 inch, 1/2 inch, 1/4 inch or 1/8 inch diameter size, and require a microphone preamplifier.
