Why Removing Earplugs For 1min Is Dangerous

Efficacy is related to the amount of time your hearing protection is used.

Indeed, each removal of a hearing protector decreases its efficacy. A product offering 30dB of noise reduction when worn 100% of exposure time (8h), will lose the equivalent of 7dB if removed for 1 minute only.

The same earplug, if worn half of the time, will offer only 3dB of noise reduction: In other words – Nothing!

That’s why uncomfortable or cumbersome hearing protection device with lack of communication capabilities are more or less useless.

Thankfully with the Sonolab Instant Fit and the Sonocom Radio attachment we have overcome these issues.
