Protecting Critical Infrastructure – Trans Bay Cable Seismic Monitoring
W5 Engineering delivered a turnkey seismic monitoring solution for Trans Bay Cable in the SF Bay Area, installing 11 MEMS sensors, wireless data systems, and DEWESoft integration for critical infrastructure protection.
Identifying Vibration Sources in Foundry Operations
Foundries present a unique challenge when it comes to industrial vibration monitoring. This detailed case study explains the methodology used to pinpoint the exact source of excessive ground vibrations affecting a local residential area. Discover how engineers used multichannel vibration analysis and FFT (Fast Fourier Transform) techniques in DewesoftX software to differentiate between multiple vibrating machines. The key finding was the identification of a complex beating effect caused by the superposition of two units operating at close frequencies, demonstrating the necessity of high-precision condition monitoring to resolve complex noise and vibration problems.
e-NVH Testing: Combining Electric Power and NVH Analysis
The rise of electric vehicles presents unique challenges in acoustics. Dive into the definitive guide on e-NVH testing—the combined analysis of electric drive power, noise, and vibration. This article explains the core principles, common challenges, and a unified multiphysics workflow to bridge the gap between simulation and real-world results. Discover how integrated DAQ solutions and advanced techniques like Order Tracking can accelerate your development cycle and achieve a "first-time-right" electric motor design.
Mistakes to Avoid When Integrating a Battery Test System
Integrating a high-power battery test system for EVs or other applications is fraught with risks.

The Critical Role of Wind Noise Testing in the EV Era
The increasing popularity and growing offering of electric vehicles (EVs), are changing many aspects associated with vehicle sound and acoustics (see our posts related to the in-cabin soundscape of the EV, for example). The classic issue of pass-by noise testing is no exception. Still a crucial aspect of automotive design and regulation, it has evolved to ensure that EVs (and other vehicles) not only meet the maximum noise limits set by various national and international regulations, but also adhere to new minimum noise requirements.
