Acoustic Resonance Services with SmartTest™

Acoustic resonance testing, also known as acoustic resonance inspection, is a single non-destructive test that measures a part’s resonances to determine its structural characteristics. The inspection examines the internal and external structure of the entire part for flaws.

A part’s resonances are determined by its structural stiffness, mass, and structural damping. Any significant structural flaws in the part, whether caused by material or process-related issues, will affect the stiffness, mass, or damping, resulting in detectable shifts in the part’s resonances. Once measured, the resonance data of the subject part is compared to a control set of data from conforming parts to determine if the part is non-conforming (NOK) or conforming (OK).

Get Started with SmartLaunch™

Achieve a pain-free launch and maximum throughput and productivity on day one, at delivery to your site. SmartLaunch™ is a four-stage, collaborative process in which we simulate your mass production context to fully optimize the inspection approach, flaw detection, yield, and throughput prior to the transfer of your system to your site. You avoid start-up pain, shorten the learning curve, and benefit from maximum productivity from the very first day of production.

SmartTest™ University

We have the most experienced team in the acoustic resonance testing business, with extensive knowledge of legacy systems dating back to the very inception of acoustic resonance testing. We perform between 50,000-70,000 tests per day in our high-volume inspection facilities. We have more level II and level III Acoustic Resonance Testing technicians than any other company on Earth. And now you can learn what we do alongside us in our facility.

SmartTest™ University is an immersive learning program where your technicians come to work in our facility side by side with our senior technicians. No distractions. Total focus on nothing but learning the daily ins and outs of using SmartTest™ at a very high level. Consider this ‘training on steroids’. In just one week, we can advance your technicians to a level II grade of understanding. This will get your people to a very deep skill level very quickly, and when they come back to your facility, they’ll bring the advanced know-how and the improved defect detection and productivity that comes with it, maximizing the return on your investment in test equipment.

Product Sorting, Rework, Packing, and More

We provide visual inspection, machine vision-based sorting, rework, packaging, labeling, warehousing*, and even transport* should they add value.

WHY SmartTest™?


Extended Bandwidth

Extended Bandwidth

Identify More Failure Modes

Bandwidth to 95 kilohertz makes many more resonant peaks available, enhancing defect detection by revealing additional failure modes not available with lesser bandwidth.

Extended Bandwidth

Ultra High Resolution

Find Smaller Flaws

Resolution of up to 89k spectral lines provides the most accurate waveform available. This reveals ever smaller flaws, eliminates false peaks, and reduces false rejects.

The fact that we perform acoustic resonance testing at very high volumes in our test centers every single day forces us to deal with real-world issues facing any user of these systems. As a direct result, we’ve developed unique features and utilities to improve both flaw detection and yield at the same time. These features and utilities enable us to accommodate lot-to-lot variation with excellent yield while providing the best in industry flaw detection, day after day, month after month. It’s more than merely extended bandwidth and higher resolution. It truly is a matter of know-how that comes only from being a full-time, high-volume user of these systems.
