Hearing protection device reduces noise across all frequencies

February 8, 2005

SensGard Sensory Protection Solutions LLC has purchased the patent for the Zwislocki Ear Muffler (ZEM) that deadens excessive noise across all frequencies. Syracuse University's Jozef John Zwislocki, distinguished professor of neuroscience emeritus, developed the device.

The device, which has received a high Noise Reduction Rating in preliminary research, resembles a pair of small, thin headphones. It folds up to a compact size and can be stored comfortably or carried in a shirt or pants pocket.

According to the company, the device allows users to hear useful sounds such as speech and warning signals without removing it.
