The CAE Intensity Array is an one dimensional sound intensity measurement system that is able to detect the source of very low frequencies. The output of the analysis is the sound intensity for each probe mapped on a picture. This measurement system is able to map stationary as well as transient noise sources. Intensity measurement systems have a very high dynamic range as there is no algorithm and no beampattern limiting this range. • Online and offline intensity analysis • Localization in small spaces • Intensity measurement • Noise leakage detection • Engine noise • Machinery acoustic • Cabin acoustics • Automotive (interieur) • For transient and stationary noise sources CAE Software und Systems GmbH I Noise Inspector \ 160 mm x 120 mm Composite Material 0.8 kg 20 48 kHz 10 Hz to 24 kHz < 33 dB to 120 dB up to 30 dB 0.01 m to to 24-Bit Ethernet -40 °C to +60 °C Non Condensing Intensity Array Array Size Array Material Weight (excl.
