In modern metrology labs, accurately measuring product noise requires more than just sound pressure values. This case study demonstrates how a metrology institute implemented a repeatable, multi-point sound power measurement workflow using SonoDAQ Pro and OpenTest, enabling reliable comparison of servers, fans, home appliances, and motors under different operating conditions. Learn how synchronized data acquisition, [...]
This guide helps users quickly set up and perform sound power measurement using a hemispherical sound power measurement frame, the SonoDAQ Pro data acquisition front-end unit, and OpenTest. Stage Completion Criteria 1. Frame installation The hexagonal base is stable, the 6 arc tubes are tightened, and the top cover is secured without shaking. 2. Microphone [...]
Automated sound power measurement speeds data acquisition, analysis, pass/fail checks, and reporting while improving result consistency.
sound power
Under regulations such as the EU Machinery Noise Directive, more and more products-from toys and power tools to IT equipment-are required to declare their sound power level on labels and in documentation, rather than simply claiming they are "quiet enough." For typical office devices like notebook computers, idle noise is often around 30 dB(A), while [...]
Sound power measurement 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 [...]
