Doc's Proplugs are intended for use by musicians, light industry and in-cabin flight attendants. This group needs protection from dangerous moderately loud high frequencies, yet they also need to hear verbal communications, machinery's functional sounds, and music with clarity. Musicians and listeners must hear the fidelity of the original sound. This type of moderate protector will have a much lower noise reduction rating than do protectors for maximum attenuation including bass, such as conventional foam insertion plugs, fully sealed custom earmolds or muff type hearing protectors.
Use VENTED Proplugs for music and noise.
The duration of exposure also plays an important role. The longer the exposure to loud sounds then the more likely is there to be damage to the ear. DOC'S PROPLUGS attenuate about 20dB across the high frequencies from 2000 to 8000 Hz. Rock concerts produce approximately 120dB. A noise level of 120dB is tolerated by the ear for about 2 hours protected by 20dB attenuation in the high frequencies. To know the sound pressure level of environmental noise one can use a sound level meter available at most electronic suppliers. If one knows the sound level, then it facilitates calculating the length of time it is safe to count on a certain protective device.
"I like PROPLUGS" SAYS Erskine, "I used them on the last tour I did, and they were handy. I didn't feel completely closed off from what was going on, and they lessened the shock my eardrums would otherwise have suffered from the loud volume."
Drummer Peter Erskine
