Musicians Earplugs are designed to replicate the natural response of
the open ear. Sound heard with these earplugs has the same quality as
the original, only quieter. The result is that speech and music are clear--you
still hear the blend clearly, feel the bass, and distinguish each tone.
Accurate sound reduction is achieved by combining a patented filter with
the specific acoustics of a custom earmold. The combination of the two
produces a resonance at approximately 2700 Hz (as in the normal ear) resulting
in a smooth, flat attenuation.
Three types of attenuator buttons are available: ER•9, ER•15
and ER•25. The number corresponds with the amount of sound reduction
provided in dB.
