This PULSE software measures the exterior noise emissions of a vehicle as it passes trackside microphones. The software works together with two data acquisition units. One is located by the microphones, and the other is located in the vehicle, with a PC. After a test run, this software gathers the
This PULSE software measures the exterior noise of a stationary vehicle and extrapolates the acoustic information to simulate the vehicle’s acoustic performance at the measurement positions of the ISO 362 pass-by noise measurement standard. The vehicle runs on a chassis dyno in a semi-anechoic chamber, and sound is measured at
This PULSE™ software works together with a material testing tube such as an impedance tube or transmission loss tube. The user places samples of the material to be tested into the tube. A loudspeaker in the tube then emits precisely quantified sound, and microphones mounted along the inside surface of the
DIRAC is a valuable acoustics measurement tool for field and laboratory acoustics engineers, researchers and educational institutions. Users can compare the acoustics of one room with another, validate sound systems and perform scale model measurements. Based on the measurement and analysis of impulse responses, the tool supports a variety of
This PULSE software is part of a complete system for determining the maximum sound power of fans.

Spherical beamforming gives an omnidirectional sound map of a room or space from a single measurement. The spherical array measures the sound arriving on its surface from all directions, using up to 50 built-in microphones. At the same time, 12 cameras take photographs of the location, and the PULSE software
Acoustic beamforming maps noise sources by differentiating sound levels based on the directions they come from. An array of microphones measures the sound field from a position some distance from the test object. Noise maps display sound strength and directivity as colours emanating from the noise sources. Using the camera
An acoustic holography system creates highly accurate sound maps using measurements made at multiple points next to the object. These use a hand-held microphone array, a fixed array, or a robot-controlled microphone array. With this method, many measurement points can be acquired simultaneously – saving time compared to traditional sound
