Emtech has addressed the problem of distortion-occlusion effect and reverberation-by allowing considerably
more high frequency amplification before feedback becomes a factor. With the addition of E-Compound to your earpiece. E-Compound
is compressed of glass Microspheres. Glass Microspheres reduce signal aberrations (distortion) in the cavity between the tympanic
membrane and the ear piece resulting in your client receiving more usable gain before feedback. E-Compound can be added to
the canal of any earpiece material.
