Brüel & Kjær Launches a New Pressure-Field Measurement Microphone and Cartridge

To help engineers and acousticians achieve accurate measurements in everyday tasks, Bruel & Kjaer has created a robust and reliable 1/2-inch CCLD pressure-field microphone - Type 4971-H-041. This new microphone was designed for measuring close to hard reflective surfaces, close to sound ports of audio devices or in flush mountings. The new Bruel microphone is also suitable for random-incidence measurements and free-field measurements with 90° incidence.
