HOCKS CUSTOM EARMOLD TEST DATA
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.
