Etymotic Earplugs ER-15
General Information
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.
Identifying the Attenuators
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.
Recommended Earplugs
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.
