It's the sound of change.Patented Technology
The ZEM's patented design uses the mechanical energy of sound waves (not electronics) to minimize sound before it reaches the human ear. The science behind its design integrates complex principles of sound physics and engineering that world-renowned Professor of Neuroscience, Dr. Jozef Zwislocki, has developed and perfected.
Unique Design
While conventional hearing protection like ear plugs and ear muffs attempt to block sound from entering the ear, the ZEM directs sound away from the ears. The ZEM chambers effectively act as a vacuum, pulling sound away from the ears.
Sound Cancelling
Proprietary sound dampening material inside the chamber filters and cancels sound waves. The ZEM technology uses the physics of wave energy to reduce sound.
Improved Results After nearly fifty years of research, Dr. Zwislocki has developed a radical new method for reducing noise. The result of this revolutionary technology extends beyond just protecting hearing. "The ZEM reduces the masking effect of unwanted environmental sounds on useful signals such as speech and improves both protection against hearing loss and the safety of an individual," says Dr. Zwislocki.

Independently tested to ANSI S3.19-1974 and ANSI S12.6-1997
Low Frequencies
The ZEM reduces sounds in the low frequencies (125Hz to 500 Hz) better than most hearing protection products. These low frequency noises are the ones that mask speech communication.
Mid-Range
The flat attenuation characteristics in the speech range between 500 Hz and 2000 Hz is what distinguishes the ZEM. Because sound is reduced evenly, there is no distortion. The result is very high speech intelligibility.
High Frequencies
Attenuation increases appreciably above 2000 Hz, the most damaging frequencies to the human ear.

How It Works
- The ZEM works by directing sound away from the ears. Sonically sealed chambers act as an extension of the ear canal. They form a vacuum that pulls harmful sounds away from the sensitive ear anatomy.
- Sound is uniformly reduced. Because sound (including the varying frequencies in the spoken word) is evenly reduced, the ability to understand speech in a noisy environment is fully maximized. And at the highest, most harmful frequencies, even greater noise reduction is achieved.
- Safety is increased. Because the ZEM produces uniformity, conversation and other vital hearing functions are made easier. The ZEM reduces low–frequency noise, the noise that masks speech and other important sounds or alerts. In other words, you hear everything you need to, while your ears get better protection than they've ever had before.
ZEM's Flat–Out Superiority In Sound AttenuationThe ZEM's ability to reduce noise at low frequencies is what distinguishes this solution from traditional ear protection. Because noise reduction is even and highly effective, speech communication is neither masked nor distorted. The patented, physics–based ZEM sound filter creates uniform sound reduction at low–frequency ranges, as well as more damaging higher ranges.
