The SensGard ZEM SG-31 was designed for high intensity noise environments. Recommended for any noise above 110 decibels, the SG-31 offers the patented Zwislocki protection from damaging noise while allowing speech and other useful sounds to be heard. Locking nylon headband positions the SG-31 firmly and comfortably on your head.
At just 1.7 ounces, get 21st century noise cancellation technology without bulk or batteries. The SG-31 is durable and folds to fit in your pocket. Includes Replacement Cuff 4-Pack.
The Problem With Ear Muffs
The theory behind the design of the ear muff (and ear plug as well) is to attempt to block all sound from entering the ear. The only way a muff can accomplish this is to create a seal around the outer ear and add material to block the sound. That is why the higher NRR (Noise Reduction Rating) muffs are generally the heaviest. The ZEM uses new and entirely different technology. The patented ZEM technology directs sound away from the ear and cancels it. The ZEM achieves a high NRR without adding bulk.
Shooting glasses do not affect the performance of the ZEM. The sound reduction as tested is the sound reduction you get. In other words, you are better protected with the ZEM.
Safe. Sound. Naturally.
The ZEM is based on remarkable technology filters out harmful, high-decibel noises. The ZEM also:
* Achieves uniform sound reduction
* Filters out the most damaging sound frequencies
* Allows easy conversation without the "echo" effect found in other hearing protection devices
Other advantages include:
* High speech intelligibility
* Increased safety
* Outstanding comfort and easy adjustment
* No occlusion or echo effect
* Designed for improved inner ear hygiene
* Light weight at less than 2 ounces
* Compact for easy storageEasy to use
* No batteries required
* New Technology For Improved Performance
* Featherweight For Greater Comfort
* Compact – Folds to Fit in a Shirt Pocket
* Adjustable Headband For a Perfect Fit
* Small Profile For a Better Look
How it Works
The ZEM is two chambers that seat on the outer ears of the user. As sound reaches the ear of an individual wearing the ZEM, the volume of sound is reduced in several ways.
The patented ZEM technology revolutionizes the way hearing protection works. Unlike ear muffs and ear plugs that attempt to block sound from entering the ear, the ZEM instead directs sound away from the ear. Sound waves will follow the path of least resistance. Because the volume of air inside the ZEM chamber is larger than the volume of air in the
ear canal, the ZEM chamber offers less resistance to sound than the ear canal. Sound waves flow into the the ZEM chamber and away from the ear.
Once inside the ZEM chamber, sound is dampened and cancelled as the waves pass through a custom acoustic material which absorbs the sound. Once past this filter the ZEM uses the physical properties of sound waves to refract and cancel.
The length of the ZEM chamber is designed to be most effective in the middle range of sound frequencies. This particular configuration achieves over 32 decibels of noise reduction and does so evenly across all frequencies.
