ETY•Plugs® HD are the world’s highest definition ready-fit earplugs. They reduce most noise to safe levels while preserving the clarity of speech and environmental sounds. ETY•Plugs HD are configured to replicate the natural response of the ear canal so that when sound enters the earplug, it is reproduced unchanged, exactly the same as the ear would hear it, only quieter.
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. Sound level meters measure at discrete times, while dosimeters measure continually over time for a more accurate estimate of risk.
ETY•Plugs HD use a tuned resonator and acoustic resistor to replicate the natural response of the ear canal. This unique construction, combined with Etymotic’s proprietary sound path, reduces sound levels evenly across the frequency range without changing the sound quality. Result: The sounds of tools, machinery, vehicles and speech are clear, but softer and safer.
ETY•Plugs HD provide almost equal sound reduction (20 dB) across the range of hearing. Foam earplugs reduce the high frequencies, resulting in muffled sound.
