ETY•Plugs™ (ER•20 High Fidelity Earplugs) were developed to provide low-cost, one-size-fits-most high fidelity earplugs that can be used in a variety of noisy environments.
The goal of the ETY•Plug™ design was the same as for Musicians Earplugs: to reduce noise but preserve sound quality; in effect, to turn down the noise but not muffle voices, environmental sounds or music.

Hearing loss from exposure to loud sound affects millions of people. Noise-induced hearing loss is preventable, but most people do not know how long they can listen to loud sound without risking hearing damage.spacerThe ER-200 Personal Noise Dosimeter is an inexpensive, handheld screening device that provides a good estimate of noise dose and alerts the user to the risk of over exposure. In cases of gunfire and other impulse noise, no conventional dosimeter measures the risk accurately because more specialized equipment is required.
