The Center for Disease Control (CDC) has provided a simple and quick test you can use to check the effectiveness of your hearing protection.
How it Works
The test sounds are bands of random noise with a center frequency of 1000 Hz. This is the same type of sound used in standard hearing protector ratings including the “American National Standard Methods for Measuring the Real-Ear Attenuation of Hearing Protectors” (ANSI S12.6). Both tracks are the same, but the second track is 15 decibels (dB) louder than the first. Most hearing protectors will block or “attenuate” sound by more than 15 dB if they are the right size and shape to fit your ears and are worn correctly. A sound that is barely audible at your threshold of hearing without hearing protection should be inaudible though hearing protection even if it’s boosted by 15 dB.
