Earasers Australia Store
The Earasers soft silicone design is based on one of the most widely used hearing aid tips in the market. There is no need for expensive trips to a specialist to get custom ear molds. The Smart Seal technology conforms to the shape of your ear canal for a more comfortable fit that you can wear all day.
Earasers soft silicone is extremely durable, easily cleaned and will last you a long time.
Whether you are a musician, attend concerts or are regularly exposed to music played at even mildly damaging levels, Earasers don't plug up your ears and muffle sound like more conventional earplugs. Manufactured by a 50 year old hearing aid company, and developed by their lead engineer – a musician for over 20 years - Earasers filter out loud noise while still allowing you to hear it right, at a safe, comfortable level.
Musicians have to be able to focus on the different layers of instrumentation. Earasers utilize a unique attenuation "V filter" to provide up to 19dB of protection in the frequencies you need it most. The result is the world's first flat frequency response earplugs.
Motorcyles / Motorsports
These earplugs have proven very popular within the motorcyle and motorsports fields given they are made to protect your hearing from damaging frequencies while you are still able to hear talking frequencies. Plus being small and invisible in your ears, they work great with helmets.
MotorSports / Racing Enthusiasts are exposed to loud engines, crowd noise, and of course wind noise. Earasers Hi-Fi Earplugs help make you a better and safer rider with some added bonuses including:
Many of you say "Hey, I'm already deaf after my years of riding!" Please know, your hearing loss will continue to get even worse than it already is if you don't start protecting your hearing now.
Dentists & Hygienists
Dental drills. They whine all day at just the wrong frequency. Earasers will protect your ears from that while you still hear conversations amazingly well. Even better, you won't have to take them in and out due to discomfort or itching or sweating which increases risk of contamination issues. Just leave them in all day…you might even go home with them in and forget they are there! Truly it happens a lot, as these are just that comfortable and clear sounding.
Dental drills generate excessive high frequencies, that over time can cause damaging hearing loss. This can cause tinnitus and ear fatigue after a full day on the job. Earasers Dental Earplugs provide the most protection between 2K-8Khz, right where it’s needed, yet allowing voices (250-300Hz) to come through the filter, not the NOISE!
Peace & Quiet Earplugs
These have been especially designed to give you ‘Peace and Quiet’. Whether that be for sleeping in a noisy environment, airplanes, a snoring partner or anywhere you find noise too much for yourself.
Yes they are well comfortable enough to sleep in.
Safety / Industrial / Noise Earplugs

About Earasers Australia
Persona Medical, our parent company, has 50 years experience in the hearing assistance field. Understanding the many challenges that accompany hearing loss, in particular the very real and lasting damaging affects of loud sound, Personal Medical’s president, Don Campbell, made it his mission to design an ear plug that anyone would be happy to wear… something they could take pride in while being proactive with their hearing care.
There are a plethora of reasons why people say they don’t wear earplugs. Perhaps you’ve heard, or even said one of the following: ”Earplugs are not comfortable; Custom plugs cost too much; My ear gets sore over time; The music doesn’t sound right; They stick way out of my ear; Too noticeable; I had some but they got dirty/grungy; I don’t like throwing them away and having to buy new ones all the time; I feel goofy when other people look at me with them in; It’s just not cool!” Well, EARasers are here to challenge all those reasons for not protecting your hearing!
Utilizing 25+ years of experience manufacturing custom ear plugs, blended with his background as a Percussionist, Guitarist and Engineer, he looked closely at the music industry and its lack of options in high fidelity ear plugs.
Don began to design an earplug that would work like a “custom product” without the huge expense, and the required visit to an Audiologist for impressions. EARasers are founded on a soft medical grade silicone that creates a “Smart Seal”. This comfortable fit allows EARasers to form to each individual’s ear shape eliminating costly customized impressions. The soft comfortable fit means EARasers can be worn hours on end, and without your ears sweating. Specifically designed, the open canal shape allows sound to travel closer to the eardrum before being filtered, creating a more natural sound which keeps the musical layering intact. While most earplugs decrease too many low and high frequencies, EARasers filter more throughout the most damaging range of the ear canal resonance, and allow more sound to come through in those very low and very high frequencies. This achieves the element of clarity that is not found in other plugs on the market today. EARasers are affordable, virtually invisible, easy to clean, and reusable. Protecting your hearing, is now “Cool” with EARasers!
Since initial introduction at Summer NAMM 2012 Convention, Nashville, the response is truly amazing! We couldn’t be more pleased! “Oh, WOW!” is by far the most used critique. No underwater, muffled, or plugged up sound. Musicians, concert goers, venue operators, parents and students in school bands, etc. continue to say wonderful things about EARasers. Testimonials speak of how clear and natural things sound with EARasers – to the point where people didn’t even realize they were working until they removed EARasers at a gig or a club and then realized just how loud the environment truly is. One of the most shocking realities that has come to light is how many people, especially young people, already have ringing in their ears; something that may never go away. What is even more surprising, is how easily that could have been prevented.
When Don dreamt of a product that would protect hearing, he wanted to be sure it would be something innovative and on the cutting edge; something that would overcome all the objections to wearing hearing protection. He aimed for a product that people anywhere could use and be proud to protect their hearing with. He achieved this very goal with the invention of EARasers! For Don, as well as the rest of the EARasers team…Your hearing ‘clearly’ matters
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 Elementary & Middle Schoolers / some High Schoolers – 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 ear bud.
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 – color 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 many 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 built 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 molded 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 ear drum. 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.
The ear is non-linear dynamically speaking, and it does not PREFER a FLAT FREQUENCY RESPONSE. The ear actual re-shapes a flat frequency response by adding its own natural resonance. As a matter of fact, Fletcher and Munson realized in the 1930’s that our ears are non-linear as well. SEE: https://en.wikipedia.org/wiki/Equal-loudness_contours
So, what is the right amount of attenuation an earplug should have? As volume increases, our ears are more sensitive to some sounds than others. We know when we listen to soft music, the bass notes and the very high frequencies seem to get lost. What is definitive is that our most sensitive region for hearing (1000Hz) up to our peak resonances (primary 2700Hz, and secondary 4000Hz), are the most sensitive to loudness growth, and the most risky for hearing loss as the SPL for discomfort is achieved at high levels in this region before either the low frequencies or higher frequencies.
It would be important for high fidelity to recognize the ear is capable of “protecting” itself to some degree, even to a great degree if needed. The acoustic reflex alone can be quite pronounced in the low frequencies reducing 10dB to our cochlea simply by reducing the vibration of the ossicles (bones). So why should we adopt a linear ear plug? How can we mimic the effect of a loud environment without causing damage? Maybe we should be reducing the more dangerous frequencies and take in to account the non-linearity of the low and very high frequencies in our sensitivity.
Our ears are able to pick up sounds both through our skull (bone conduction) and through our ear canals. The cochlea is mounted in our skulls. When we are in a loud environment, more of our bone conduction is in use than in a conversational environment. If we apply too much reduction to the low frequencies, our own voice will sound very odd due to the increase in our “head voice” bone conducted energy compared to the energy that travels through our ear drum and into the cochlea. Our brain is constantly monitoring the comparison to the two levels (bone vs. air conduction) and making decisions about the sound quality based on this comparison. That is why you think you sound different on recordings…because the recording doesn’t have the bone conducted energy that you hear through your skull/cochlea pathway. Since there is essentially no occlusion effect above 1200Hz, we need an earplug that doesn’t reduce ANY volume below 1200Hz. OK, so maybe that is a little extreme. What is the purpose of the earplug then? We must assume that the environment is significantly loud, and that some reduction is desired.
Now, a study performed by National Acoustic Laboratories, Australia, (NAL) in 1999 confirmed some additional psycho-acoustic phenomenon that muddies the data even more. It appears that simply placing an earplug in your ear causes an “insertion effect” to desire 7dB more gain in the low frequencies in order to maintain the same perception of low frequencies versus 1000Hz. Fascinating! (This is not to be confused with insertion loss…the loss of naturally transmitted energy to the eardrum). Although researchers have not proven the reason for this effect, it may have something to do with the increase in bone conducted energy versus air conducted energy (skull versus eardrum) and the increased awareness of self-generated body sounds including blood flow to the cochlea. What we can say is that this is another bit of evidence telling us not to reduce the low frequencies as much as we may otherwise assume. But, it is becoming more clear to me that earplugs should not be flat attenuators…maybe flat response shape, but not flat attenuators. Even with earplugs, I don’t think the goal is to reduce the volume to conversational levels (65-70dB SPL) but to make them retain the nuance of the music at a higher level without being objectionable, or destroying the ability to hear the layering of different instruments or sounds, localizing, and certainly reducing the likelihood of hearing damage (evidenced by ringing in the ears).
This is a little understood cause and effect. A recent study showed that 75% or more of young adults experienced ringing in their ears after attending clubs or certain venues where music was playing. Yikes! Typically, ringing in the ears is accompanied by a temporary threshold shift which has been shown to be a pre-cursive indicator to eventual sensorineural hearing loss.
By studying the natural resonance of the average ear canal, we can also see a secondary peak of 9dB at around 4000Hz and gradually reducing to no additional resonance beyond 8000Hz. (Some people also experience the above mentioned “insertion effect” at 3000Hz but not as often as the lower frequencies.) What we can say is that these higher frequencies, above the secondary peak, especially beyond 8000Hz, also show an improved loudness growth function. After all….just add on another octave and you are practically at the maximum higher frequency range of hearing. Loudness growth approaches infinity. In other words, the higher frequencies also have a natural built-in attenuator. But, here is the catch. We know that higher frequencies are rarely sustained for any period of time….at least that which remains audible. The lower threshold of hearing in the higher frequencies is easily masked by high intensity, low frequency sounds. For example, the bass drum or bass guitar will easily overtake the sustained resonance from a high frequency cymbal roll. If we reduce the high frequencies by the same amount as the peak frequencies, we get a very unnatural sound. The higher frequencies have a wider range in which the nerves of the cochlea overlap to receive the signals. Thus, there is more power perceived for noise stimuli in high frequencies than for pure tone stimuli. We assume for this discussion, that much of the music generated above 4000Hz is broader band and not pure tones. For relative reference, the highest piano note only goes to 4186Hz.
These very high frequencies are used for clarity of speech, the unvoiced consonants such as “th” “f” “sss.” These sounds should not be over-attenuated as their ability to be vocalized is limited and thus, even with amplification, they are difficult to reach the uncomfortable levels of most humans. If they are reduced by too much, speech definition is compromised, cymbals become dull and everything that should be snappy, becomes dull. The open, airy feeling is lost. Often times, we associate reverberation with a large room and the lack of reverberation with a very small, closed in container. One is rich in quality, the other lacks it. Because the ear sums the high frequencies due to the way the nerves in the cochlea operate, the equal loudness contours underestimate the frequencies above 1000Hz. In practice, with our situation being music, you can actually raise the equal loudness contours above 1KHz (Suzuki, 2002). This is reason to let the ear do a little more of the work in protecting itself against loud high frequencies…because it has some headroom to spare.
In most musical situations, a normal listener would not enjoy, nor tolerate much more than 10-15dB’s more sound pressure than other normal hearing listeners uncomfortable limit. That 10dB would represent double the volume perceptually. Thus, 10dB seems that a good place to start. If we start with 10dB attenuation at 500Hz…. where do we go at 1KHz and 2.7KHz…etc? Remember that our ears naturally resonate the most at 2700 Hz and the equal loudness contours show the ear is most “sensitive” to loudness at the 2700Hz region. When we amplify sounds, our ears have no way to notch out this region.
The real danger is in the 1K-4KHz region. Now, how much should we adjust those frequencies? Take a look at our natural resonance, about 18dB of amplification at 2700Hz for conversational levels. But, we don’t need that resonance for 95dB SPL sounds! You can see from the equal loudness contours, an attempt by our ears to begin to dampen and restore a flatter response. Our ears just aren’t doing enough to protect us here. Maybe pre-industrial revolution we would be fine, but the intensity of high frequency sounds we generate, and the short and repetitive durations add up to trouble. An earplug which reduces 15-25dB’s at the peak frequency would be desirable if simply to remove the gain from the natural amplifier we carry with us that was, for the sake of survival, intended to amplify soft sounds for hunting, and for the sake of communication, amplify the higher sounds for speech clarity at conversational levels or lower.
