Etymotic Musician Filters
$89.00
This product page is for the Etymotic Filters only.
The Etymotic musician ear plugs with filters, or buttons, have a diaphragm which functions as an acoustic compliance, while the volume of air in the sound bore of the custom ear-mold acts as an acoustic mass. The combination of the two produces a resonance at approximately 2700 Hz (as in the normal ear), which results in smooth, flat attenuation.
Etymotic Filters & Reduction Levels
- ER-9 Provides flat 9 dB sound reduction through the mid range and 15 dB in the highs (Best for vocals, keyboard, acoustic)
- ER-15 Provides uniform 15 dB sound reduction across frequencies (A great all around musician earplug filter)
- ER-25 Provides 25 dB relatively flat sound reduction across frequencies (Best for drums, brass, and loud instruments)
