Custom Noise Braker Test Data

Custom Noise Braker hearing protection earplugs have been tested by Michael & Associates in accordance

with The American National Standards Institute (ANSI) , and CE tested by Sport Critt Loisirs.

Our proprietary Hocks Noise Filter® is used in other products, and while attenuation data should be similar, the test data on this site is for Hocks Noise Braker® custom earplugs only.

Please contact the individual provider for testing results.  The process by which your hearing protection was manufactured will vary based on a variety of factors, and the test results may vary.
