Hocks 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.

The tests measured noise attenuation (reduction) at varying frequencies. Testing the frequencies is similar to comparing the noise reduction while you play the key of C at varying locations on a piano keyboard.

Our proprietary Hocks Noise Filter® is used in the manufacture of other products, and while attenuation data should be similar, the test data on this site is for Hocks Noise Braker® units made in Hocks Earmold Lab 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.
