Bruel Kjaer Remote Control ZB 0015, Sound Intensity Set
Microphone pairs matched for phase and
3519 and 3545: 20 Hz to 10 kHz
Minimal shadow and diffraction effects
Well-defined acoustical microphone separation
The measurement of sound intensity (sound power per unit area) is increasingly being used as a routine technique in a wide range of noise investigations. The method permits the determination of sound power from direct measurement of sound intensity, even in situations where pressure-based measurements would be impossible. Since the method does not require special acoustic environments, such as reverberation and anechoic chambers, significant savings can also be made.
Type 3520 is a two-microphone probe kit for measuring sound intensity.
The probe set includes Microphone Pair Type 4183. These 1 /2" microphones feature patented phase-corrector units making precision low-frequency phase matching a practical possibility, leading to increased measurement range and accuracy.
Includes Remote Control Handle ZB 0015, Microphones 4183 Part 1, 4183 Part 2, Spacer 12mm UC 5272 and 50mm UC 5273. Ellipsold Windscreen UA 0781 and Spherical Windscreen UA 0782. Unit includes a self test warranty.
Item has come from a working environment. Calibration available to winner for additional cost. Last calibrated 1982.
