The FitCheck Solo system can be used to test the fit and performance of any brand and type of insert hearing protector. Developed by NIOSH as HPD Well-Fit™, FitCheck Solo is the commercially available version of this fast, reliable fit test system for worker hearing protection. It is the only system that can measure any earplug with the actual plug worn the way it was fit that day.
FitCheck Solo software is fully customizable and flexible. You select which frequency bands (125 to 8000 Hz) are tested to find the best hearing protection for different workplace noise conditions.
FitCheck Solo requires only a Windows OS computer with a high-definition sound card, a mouse with a scroll wheel, and sound-isolating headphones. It provides results within seven to 10 minutes.
