In our February edition of In Motion, we highlight an application story where we visited the world's quietest room to put the ORCA™ motor to the test and find out just how quiet it really is. This edition also delves into the technicalities of motion fidelity, exploring how data distortion can impact measurement quality and system accuracy. Finally, we are proud to share a significant milestone in our leadership with the announcement of Jeff More as our new Chief Executive Officer.
Just How Quiet is Quiet? ORCA™ Motors Bottom Out the Noise Floor in the World's Quietest Room at Orfield Laboratories
In August 2025, Iris Dynamics visited the quietest measured environment on Earth: Orfield Laboratories in Minneapolis, to test just how quiet ORCA motors are. During multiple tests under ISO controlled conditions, the ORCA motor was measured barely above the sound floor at less than 15 decibels (dB).
"I would say of the products that we've measured, it's probably the most extraordinarily quiet product. As a design engineer, I'm really impressed by the control engineering. The sound of the motor is barely above the noise floor in the anechoic chamber. What that really means is that you can't hear it."

How Motion Fidelity Impacts Measurement Quality ||
Reduce Velocity Ripple, Eliminate Cogging, Improve Force Stability

If your test data is unreliable, the problem may not be your sensors. It may be your motion system. Our latest article explains why true precision in test and measurement is not just about resolution, but motion fidelity. Latency, friction, and force ripple, can contaminate results and hides the real behavior you are trying to measure.
If your application is within materials testing, fatigue analysis, friction studies, or dynamic load characterization, this is for you. Learn how low latency, integrated actuation can eliminate hidden disturbances and give you test data you can trust.
