Intensity probe Microphones

Technique and applications Intensity measurement is a practical tool for locating and ranking sound sources and determining the emitted sound power. The method is based on the simultaneous deter­ mination of sound pressure and particle velocity using two closely spaced, face-to-face measurement microphones. The probe is also named a pressure-pressure probe and is especially designed to measure the sound intensity of complicated sound sources as well as to minimize the influence of the sound field. Sound intensity probe with pre-polarized microphones The probe is equipped with two ½ ” pre-polarized intensity microphones which meet the requirements of the IEC 61043 standard for a Class 1 intensity probe and are carefully phase-matched to ensure maximum measurement accuracy. Together with the two CCP preamplifiers the probe is directly compatible with LMS’ 4 mA ICP® input modules. Variable frequency range The frequency range is determined by the distance between the two intensity micro-phones. The probe comes with a selection of spacers that enables diagnostics from 50 Hz to 10 kHz. These spacers are easily interchanged without having to dismantle the probe. Dedicated remote control The Intensity Probe Type 50AI-L is a dedicated LMS probe with built-in USB-remote control. Its well-known, four-button interface allows for single-handed operation of the application software and gives the opportunity to keep focus on the object being measured.
