DECIBULLZ EARPLUG ONLINE FIT CHECK
Follow the instructions below to perform a quick test of whether you are getting at least a minimal 15 decibel (dB) level of protection. If you are unable to get the level of protection you need, reach out to email@example.com and our expert team will be able to assist you.
1. For best results, conduct this test in a quiet room (background noises can interfere with the test sounds). Listen through speakers on your computer. Over-the-ear Headphones can be used but must cover the entire ear and not make any contact with the inserted earplugs. Keep your head still and the exact same distance from speakers while playing both tracks.
2. Play Track 1 and adjust the volume so the sound is barely audible. This should be the absolute lowest volume you can detect.
3. Insert on your earplugs. When using foam tips compress foam by rolling as small as possible and quickly insert into ear. Allow foam to expand for 1 minute.
4. Do not adjust volume and Play Track 2 and listen for the test sound. You should not be able to hear the test sound if your hearing protection is fitted properly.
5. If you can hear Track 2, re-fit your hearing protection and repeat Step 4.
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.
Improper fitting or misuse of earplugs will reduce effectiveness of earplugs and could result in hearing loss or injury. Test thoroughly in progressively louder environments. Always make sure earplugs are inserted correctly before use.
