Earsonics have produced a remarkable generic earplug with an innovative acoustic filter, designed by a leading French sound engineer to still give you a real world response even when you have a earplug firmly in place.

The idea of the Earsonics Pad is to compensate for the ears physical make up. A bit like the loudness button on an amplifer, it boosts the low and high frequencies as the sound level decreases. The human ear is less likely to hear these nuisances in the sound at lower sound levels, so they are lifted to compensate. The result is remarkable for a passive acoustic filter, you will also have an overall sound reduction of 16dB.
