3M™ E-A-Rfit™ 393-2005-50 E-Z-Fit Probed Test Plugs are a modified version of the 3M™ E-A-R™ E-Z-Fit ear plugs you know and love, made to be used with the 3M™ E-A-Rfit™ hearing protection and training system.
3M™ E-A-Rfit™ System: How it Works
These Probed Test Plugs allow the user to insert the ear plugs as usual, then a technician connects the small sound tubes that exit the test plugs, into the E-A-Rfit™ leads, pushes the go button on the computer and seconds later, you both see a screen showing your PAR, or personal attenuation rating. Now you can be sure that the ear plugs you rely on are giving you or your employees the protection they need. If you get a failure rating, meaning the ear plugs are not properly inserted or they do not fit the individual being tested, you can simply adjust the method of inserting the ear plugs and try again, or failing that, try a different ear plug or ear muff. When you are done, you KNOW how much protection you are getting from your ear plugs, and you know how to properly use the ear plugs or ear muffs to get the most protection out of them.
E-A-Rfit™ simply listens to a few seconds of pink noise, sampling the volume inside the ear canal, on the other side of the ear plug, and comparing that volume to the volume of sound it hears at the outside of the ear plug to determine exactly how much of the noise that is present is getting past the ear plug. This test method is simple, fast, accurate, and reliable. Best of all, it helps provide crucial training feedback right on the spot, in terms the user can instantly recognize.
