The E-A-R™ Classic™ is ideal for moderate to high
noise levels, and is particularly suited for high
frequency noise in both the workplace and leisure
environments. Examples of typical applications include:
� Automotive
� Chemical & pharmaceutical manufacture
� Construction
� Light engineering
� Metal processing
� Textile manufacture
� Woodworking
The E-A-R™ Classic™ Roll-Down earplugs are
designed for insertion into the ear canal to help reduce
exposure to hazardous levels of noise and loud sound.
This product is available in corded and uncorded
versions.
The uncorded version is also available in One Touch™
Dispenser format.

Polymer
The following materials are used in the manufacture of
this product.
Key
Mf = Mean attenuation value
sf = Standard deviation
APVf = Assumed Protection Value
H = High-frequency attenuation value (predicted noise level reduction for noise with
L(C) – L(A) = -2dB)
M = Medium-frequency attenuation value (predicted noise level reduction for noise with
L(C) – L(A) = +2dB)
L = Low-frequency attenuation value (predicted noise level reduction for noise with
L(C) – L(A) = +10dB)
SNR = Single Number Rating (the value that is subtracted from the measured C-weighted
sound pressure level, L(C) in order to estimate the effective A-weighted sound pressure
level inside the ear).

� Proprietary soft energy absorbing polymer foam
� Firm material with slow recovery time helps achieve
good fit
� Special cylindrical shape that fits most ear canals and
provides a reliable seal
� Extremely soft foam helps provide low pressure
inside the ear canal thus increasing comfort and
wearability
� Exposed cell surface texture resists movement and
helps maintain an effective seal
� Excellent sound attenuation characteristics
� Supplied in a re-sealable pillow-pack for ease of use
� Sweat and humidity resistant which helps improve
comfort. Ideally suited for use in hot and humid
conditions
� Available in both corded and uncorded versions
