The problem with conventional earplugs

Most earplugs attenuate more than necessary when fitted properly.

Too much attenuation in the high frequencies makes speech and music sound muffled and unclear.

Users don't always wear them deeply enough in their ears because they want to hear speech and machinery.

The solution: ER earplugs

ER-15 and ER-25 buttons are designed to match the ear's natural response when attached to a custom earmold.

The result is that music and speech can still be heard clearly, but will not be as loud.

The theory and design of flat response attenuators
A flat-response attenuator must have a frequency response that follows the shape of the natural frequency response of the open ear, but at a reduced level.

The ER-15, ER-15SPTM (sports plug) and ER-25 use diaphragms similar to a passive speaker cone, to achieve the desired response curve.

ER-15SP: In order to provide the smallest possible size, the 6 kHz "side branch resonance" (which smoothes the ER-15 response above 3 kHz) was sacrificed in the ER-15SP. The result is a plug with less attenuation at 6kHz, but is otherwise similar to the standard ER-15.

"Use of ER-15s by the National Football League and some large university teams has been instrumental in helping control noise interference during play. I have found that it is most effective to use ER-15s in conjunction with a total noise reduction and signal modification program."

What Musicians Say:

Burl Lane, contrabassoonist:
"ER-15's make this job fun again." Bill Buchman, bassoonist:
"I'm in front of the trumpets and trombones... The ER-15s let me hear myself playing and also the entire orchestra so I can correctly perceive my relation to the other instruments."

Laurence Neuman, violist:
"These earplugs don't block out what I want to hear. They just tone it down and keep things equalized. I also wear mine on planes and the CTA, which is incredibly loud; I love them."

Lee Lane, violist:
"I'd tried everything... When these came along, I was absolutely delighted; they've been very successful for me."

Who uses the ER-15s and ER-25s?
Those who are exposed to high sound levels for various time periods and need to hear accurately:

• Musicians
• Dentists
• Disc Jockeys
• Airline pilots and personnel
• Sound crews
• Truck drivers
• NFL football players (no kidding! ER-15s have reduced offiside penalties)
• Band teachers
• Traders
• Construction workers
• Recording engineers
• Industrial workers
• Offshore oil workers

And those who prefer to hear without discomfort:

• People with tinnitus
• Airplane and auto travelers
• Spectators at sporting events and concerts
• Individuals with a sensitivity to loud sounds
