ER-9/ER-15/ER-25 Musicians Earplugs

The custom fit and soft vinyl construction provide years of use. The ER-9, ER-15 and ER-25 are now used by professionals in all audio-related fields — live performance, sound engineering, recording, critical listening, etc.

The ER-9 attenuates (reduces) sound pressure levels by 9dB across the entire frequency spectrum at the ear. Levels are reduced by 15dB with the ER-15 and 25dB with the ER-25. 9dB, 15dB and 25dB filters are interchangeable on the same earpiece depending on the application.

Precision Laboratories is the only manufacturer to incorporate a snap-ring into the ER earmold to prevent the attenuating filters from falling out under strenuous use.

When accurate listening at safe levels is critical, ER-9, ER-15 and ER-25 Musicians Earplugs help eliminate dangerous SPLs and enhance your listening experience!

Contact a Precision Laboratories affiliated hearing healthcare professional for price and availability.

Replacement filters may be purchased directly from Precision Laboratories for $60/pair.

The Hearing Alarm

The Hearing Alarm accurately measures background noise levels and visually indicates whether it's in the safe range (green light), high range (yellow light, approx. 85dB to 109dB) or dangerous range (red light, approx. 110dB and above).

The ease with which the portable, battery-operated Hearing Alarm measures sound levels makes it ideal for people who want to protect their hearing.
