Etymotic Research ER-15 Manual de usuario
Identifying the earmolds
Right earmold: •red dot
Left earmold: •blue dot or no marking
Insertion
Moisten mold for ease of insertion. Pull the ear
outward and upward while easing the mold into the
ear canal.
Cleaning
Remove attenuator button from mold. Use water and
mild soap on the mold only. Dry mold before replacing
button.
Reasons to replace the molds
and/or attenuators
Discoloration,shrinkage, cracking, hardening of the
earmold material,or deterioration in performance.
General Information
Most attenuator buttons have the number 9,15 or 25
stamped on the button. Some have either a black or
a white sealing ring,others are plain, depending on
the style,color,attenuation characteristics and the
manufacturing process. These identifiers and bands
do not affect the performance of the attenuators.
Each attenuator is carefully constructed and measured
to assure uniform acoustic properties.
Solid Plugs
Some inserts are solid; some have a diaphragm sealed
with epoxy. The average attenuation of Etymotic’s
sealed button is 30 dB, measured at E-A-RCAL
Laboratories by the ANSI Real-Ear-Attenuation-at-
Threshold method. Note:When the sound channel
of the earmold is plugged,the total attenuation is
dependent on the insert plus the earmold seal.
Identifying the Attenuators
Musicians practice and perform
in a variety of different settings
and they are exposed to high
levels of sound, sometimes
for long periods. They require
different amounts of protection,
depending on the sound levels
they encounter during rehearsal
and performance.
Buttons are interchangeable.
Some musicians use one type
of attenuator in one ear and
another type in the other,
depending on the source and
location of sound.
