White Paper, Video Discusses Sound Measurement in Field Tests
The challenges associated with sound measurement in field tests are the focus of a white paper and video developed by Multi-Wing America to help engineers and equipment manufacturers. The ISO standard 3744 environment for sound measurement over a flat plane requires a completely open space with no bounding or reflecting surfaces other than reflecting plane(s), such as those provided by a hemi-anechoic chamber.
The white paper illustrates the complexities of sound measurement by providing sound propagation in ideal and real-word conditions. The video demonstrates sound measurement of fan noise with a sound meter at given distances in a real-world environment.
