The following test data was made by two different companies on our
Standard Noise Braker® ear plug.
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 other products,
and while attenuation data should be similar, the test data on this site is for
Hocks Noise Braker® units only.
