Sonic Valve hearing protectors are special patented hearing protection devices designed to allow low level sounds, not harmful to hearing, to pass through. But offer effective hearing protection against high level, high impulse noise which are harmful to hearing. Generally used in aviation, music and sound engineers to reduce "noise hangovers" and ringing ears.

Unlike ear muffs and solid ear plugs, the Sonic Valve II hearing protectors allow you to hear total sounds and conversations. They are designed with a series of noise restrictors and moving diaphragms which makes it particularly efficient in reducing the amplitude and energy content of impulse noises reaching the ear drum.

Generally used by musician's, pilots, race car drivers and industrial workers, these devices are designed to allow the ear canals to be open for air circulation until sufficient noise levels activate the patented valve system to close down and protect the inner ear from incurring hearing damage.

Musicians practice and perform in a variety of different settings and they are exposed to high levels of sound, sometimes for long periods of time.

These inexpensive, high-fidelity earplugs can be used in a variety of noisy environments to reduce dangerous sounds levels evenly, which preserves natural sound qualities and balance. They are excellent for industrial workers, concert spectators, airplane travelers, marching band members, sound crews, musicians and more. (20 dB attenuation)

The ER-20s are DIFFERENT than conventional earplugs. They actually reduce the dangerous sound level evenly (using a tuned resonator and acoustic resistor) to preserve the balance. You still hear the blend clearly, "feel" the bass, and are able to distinguish each tone.

Here is a list of several people who benefit from the ER-20 earplugs...

• Aircraft - crews, passengers, pilots
• Athletics - athletes, coaches, spectators
• Construction - carpenters, equipment operators, steel workers
• Emergency Vehicles - EMT's, highway patrol, firefighters
• Industrial - factory workers, students, supervisors
• Leisure - concerts, night clubs, noisy restaurants, sporting events
• Medical - Dental - dentists, hygienists, technicians, surgeons
• Drivers of - heavy equipment, motorcycles, race cars, pit crews
• Musicians - vocalists, musicians, directors

The Combat Arms (Indoor/Outdoor) earplugs were specially developed for the armed forces and law enforcement. Their patented designed allows the user to hear low-level sounds critical to mission safety such as conversation, footsteps, rifle bolts and approaching threats. When needed, the plugs "filter" reacts to provide instant protection from high-level noises like weapons fire and explosions. It's that easy and that quick.

Insert the Yellow End:
This end features a nonlinear acoustical design with a calibrated filter within its end. This allows most low level sounds to be heard clearly during use. When a loud impulse noise such as weapons fire or explosives occur, the filter react instantly and suppresses the noise to a safer level. The chance of permanent hearing damage or disorientation from explosions is greatly reduced or eliminated.

Insert the Green End:
This end provides steady protection with an NRR of 22dB. It is ideal for constant high-level sound limits (85dB and above) such as aircraft, watercraft, armored vechiles or machinery. In this position, the plug provides excellent protection against noise, and will limit speech and other ambient sounds that the yellow end will allow.

Product comes packaged with a carrying case and cleaning tool.
