Sound power testing is used to quantify the total acoustic energy radiated by equipment, with sound power level, Lw, as the key metric. Unlike sound pressure level, which only indicates how loud a sound is at a particular point, sound power is better suited to noise benchmarking and compliance declarations across sites, laboratories and production […]

Learn how to identify acoustic imaging false positives, ghost images, and beamforming artifacts in acoustic cameras used in noisy plants.

In many practical applications, data acquisition is not performed in an "ideal laboratory" environment. The device under test may be connected to mains power, distribution cabinets, frequency converters, or large electromechanical systems, while the acquisition card on the other side is connected via USB or Ethernet to a computer-sometimes operated directly by a person. These […]
