NIOSH (1998). Criteria for a recommended standard: occupational noise exposure.Cincinnati, OH: U.S. Department
of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, and National
Institute for Occupational Safety and Health. DHHS (NIOSH) Publication No. 98-126.

The U.S.Environmental Protection Agency requires manufacturers
to print a noise reduction rating (NRR) on all non-custom earplugs.
The formula used to determine NRR includes an adjustment for test
variability,individual variability,and for those persons who do not
wear ear protection as instructed.When worn properly,Etymotic
earplugs provide more sound reduction than the assigned NRR
value.Laboratory data on subjects wearing properly sealed
ETY•Plugs

™

shows between 18-22 dB average sound reduction
over the 250-8000 Hz frequency range,but the NRR calculated
from the same data is 12 dB.

ETY•Plugs earplugs use patented
technology that replicates the natural
response of the ear canal so that sound
heard with these earplugs is as clear as
the original, just quieter. The BabyBlues

™

earplugs were created to fit smaller ear
canals. ETY•Plugs earplugs have nearly
the same fidelity as Etymotic’s Musicians
Earplugs

™

(custom earplugs worn by
professional musicians) and are a
low-cost alternative.

About ETY•Plugs (2 Sizes)

About Noise Reduction Rating (NRR)

ETY• Plugs provide almost equal sound reduction (20 dB) across the range of
hearing. Foam earplugs reduce the high frequencies, resulting in muffled
speech and music.

Musicians Earplugs™

How much noise is too much?

Hearing loss is a function of exposure time,the average sound level,
and the peak lev

el of very loud sounds. Exposure to excessive noise
can cause permanent hearing loss depending on the intensity and
duration of the sound. Some persons are more susceptible to hearing
loss from high-level sound than others.

Preserve sound qualit

y

The human ear o

verloads at high sound levels,making it difficult

or impossible to distinguish speech or the musical blend.

Prevent ringing in the ears

Ringing in the ears (tinnitus) and tempor

ary hearing loss can occur
from a single concert, sporting event or sudden loud noise like a
firecracker. Even if a temporary hearing loss recovers over a period
of hours to days,there is a risk that repeated exposure to loud noise
could result in permanent hearing loss.

Noise-induced hearing loss
can be prevented!

ETY•Plugs™High Fidelity Earplugs lower noise evenly at all frequencies
to preserve sound quality. Sound is not muffled. Music is heard clearly,
but at a safe,reduced volume.

The Good News

F

ACT

More than 30 million Americans are exposed
to hazardous sound levels on a regular basis. About
one-third (10 million) can attribute their hearing loss,
at least in part, to noise. Exposure occurs in the workplace,
in recreational settings, and at home.
