Earasers FAQ

What size should I choose?

Research and fitting history suggest the following general guideline, however, each individual’s ear canals are unique:

X-SMALL – typically used by youth, such as Primary Schoolers and some High Schoolers – And a very small % of the adult population.

We always recommend you try the SMALL before attempting the X-SMALL.

SMALL – typically the majority of Women and Younger Males (late 20’s and younger). Works well for some Adult Males who have a smaller ear canal.

MEDIUM – typically these work well with Adult Males (later 20’s and up) who do well with the average earbud.

LARGE – enjoyed by some males over 60, a Very Small % of the adult population. Some women as well. (Did you know Women, that being able to wear this size EARasers earplug is a sign of “Genius!?!” (Thank your biological parents.)

STILL WONDERING ABOUT THE RIGHT SIZE?

Time to think back to your personal past experience with earplugs and/or earbuds. Any indication you may have small or tiny canals? If so, we recommend you try the SMALL size. If standard ear-buds seem to work well for you, then perhaps you would do well with the MEDIUM.

How do I know if I have an appropriate seal?

Once you’ve ordered your size, you will need to insert both EARasers earplugs (Red is Right, Blue is Left – colour side indicator stripes facing you, then bring straight back so line ultimately ends up facing towards the back of your head.)

Drop your jaw, and gently pull either up or down on your actual ear with one hand, while gently inserting your EARasers earplugs with the other hand. The string with the ball is simply to help you remove it from your ear, so pressing on it won’t hurt it.

Dropping your jaw will help to straighten your ear canal to achieve a better seal. You will know you have an appropriate seal when YOU begin to speak. While everything else will sound normal with EARasers inserted, your own voice when speaking should result in “a head voice” or “an occlusion when you speak”. Similar to you putting your fingers in your ears and speaking.

If you don’t find that “head voice” when you speak, repeat the above steps to see if you can find that. First, make sure you have Red in Right and Blue in Left and that the lines are positioned properly.

Often, we see people rotate their hand while inserting and end up putting their earplug in Backwards. – Be certain you’ve not done this.

EARasers should never hurt your ear canal, or be uncomfortable, however, they do need to be able to seal your ear canal. If you are unable to achieve your “head voice when speaking”, then you may need to swap sizes.

How do I clean my Earasers?

EARasers can easily be cleaned following the steps below. Be certain to NEVER stick or poke anything down into the tip, or opening, of your earplug. Doing so WILL result in a popped, or unsecured, filter.

To clean your EARasers, simply rinse off under warm water and let dry. Water will not harm the filter, however, try to refrain from using soaps as they may cling to your filter and create build up.

If you use wipes or wet towelettes, be sure to use only “Alcohol-Free” products on your EARasers. Products with alcohol will dry out the silicone over time and may compromise the integrity of your earplug.

It is normal for ears to generate earwax. While we highly recommend you clean your ears each time prior to inserting your earplugs, we realize this will not always happen. If wax, or debris, does go into the tip of your EARasers earplug, it can gently be removed by simply using a “Soft Bristled Brush” such as a Soft Head Toothbrush, or a soft Baby Nail Brush, eyebrow brush. (These items can usually be found in any Grocery, Supermarket, or make-up counter.)

Using warm water and the soft bristle brush, gently work the wax and debris out by making soft motions over the opening. The soft bristles will gently remove the wax without having to insert anything down into the tip.

Everything sounds so clear with my Earasers! How did you do it?

There are several reasons why EARasers provide amazing listening clarity.

First, most earplugs, including Custom moulded sets, place the filter outside the opening of the canal. Sound is then filtered and still has to travel through a narrow tiny curved tube (or canal) to reach the eardrum.

EARasers patented open design was created to let sound travel farther more naturally before it reaches the filter which is strategically placed at the tip, nearer the eardrum. By reducing the travel distance, EARasers naturally achieves clarity.

Secondly, EARasers use an innovative “V” (variable) filter. EARasers focus on the most damaging range of the ears natural resonance (around 3150 Hz) and filters approx. 19dB.

For most people this keeps concert sound and loud music underneath the uncomfortable and harmful range. EARasers filter less in the normal and natural range (1000 Hz and less) so that most of the sound can come through, and also above 8000 Hz where cymbals and “S”‘s & “T”‘s are in speech.

By reducing less in the ranges where heavy filtering is not necessary, it creates a clearer more natural sound instead of an “underwater” or “muffled” sound. No more “plugged up” feeling!

What is the relationship with music and hearing loss?

Persona Medical has been developing hearing aids for 50 years, so we know a lot about hearing loss. What we know is that the majority of hearing loss we see in first-time patients is between 2000 Hz and 8000 Hz.

In musical terms, that’s two octaves….starting three octaves above middle C on the piano, and extending to five octaves above middle C (256Hz). 2700Hz is the natural peak resonance for humans. No wonder this is where the damage is done.

Thousands of years of evolution carefully crafted our ears to focus on the unvoiced consonants of speech that are difficult to project with the efforts of the pressure of our lungs pushing air through our voice box.

It was not preparing itself for the onslaught of noise and volume the 20th Century had in store. Yes, our ears naturally resonate the higher frequencies of conversational speech, but certainly were not intended to resonate a Marshall Amplifier already producing 100dB SPL+ of sound!

The ear is a natural resonator…but not below 1000Hz and very little beyond 5000Hz. Again….keep in mind, that the majority of music will be below 1000Hz.
