No. The reason no ear plug can block 100% of the sound you hear is because sound reaches the inner ear’s sound receptors mainly through 2 ways:
• Ear canal – where sound is conducted through the air
• Bone conduction – sound passing directly to the inner ear
Completely blocking out the ear canal is bulk of the solution (if fitted correctly of course), but you will still be able to hear about 5% of the sound which reaches your inner ear primarily via bone conduction.
Also to those with sensitive hearing, when the volume is very low, your hearing becomes more acute, so the sound seems to be much louder than it actually is. Human hearing automatically adapts to the volume by adjusting the acuity of your hearing, turning it down when things are loud and up when things get quiet. This is why putting on hearing protection is important in loud environments that are seemingly ‘bearable’ – you get used to it, but you really shouldn’t!
That being said, our general guideline is this:
When fitted correctly, ATTENU8 reduces noise to more bearable/comfortable levels for you to execute your task while attaining the hearing protection you need.
