Type 3599 is a two-microphone probe kit for measuring sound intensity. Specially designed for use with Brüel & Kjær’s range of sound intensity analyzers, the probe set includes Remote Control Unit ZH-0632 and ½-inch Sound Intensity Microphone Pair Type 4197 enabling 1/3-octave centre frequency measurements between 20 Hz and 6.3 kHz. The upper 1/3-octave centre frequency to 10 kHz can be extended using pressure correction.
- Sound intensity measurements using two-microphone technique, in accordance with IEC 1043 Class 1
- Sound power measurements in accordance with ISO 9614 – 1, ISO 9614 – 2, ECMA 160 and ANSI S 12 – 12
- Sound intensity mapping
Used with 1/2-inch Microphone Pair Type 4197, the probe complies with IEC 1043 Class 1. 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.
Type 3599 can be used with data acquisition hardware LAN-XI Type 3050-A with UA-2104-031.
