Frequently Asked Questions
EarAID™ Product Details:
Who makes this device?
EarAID is manufactured by Lucid Audio, the pioneers of inner ear technology in the USA, having over 100 patents on inner ear devices.
What is the best eartip to use with the EarAID earpiece?
Ears come in different shapes and sizes. To obtain optimal sound quality and noise isolation, eartips must seal off the ear canal. EarAID earpieces are packaged with 7 pairs of eartips. We recommend experimenting to see which eartip provides the most effective seal for you, but generally the foam eartip provides the most protection.
I already have some hearing loss; is it too late?
No. Though hearing loss is irreversible, what hearing you have left is still possible to preserve and protect. Think of patients who ask us "Doc, I have lost some teeth, is there any point to saving the rest?" Without protection, your remaining hearing could be lost forever.
What are filters and what are they used for?
EarAID electronic earplugs are equipped with special filters that prevent ear wax and other agents from entering the electronics. If a filter becomes clogged, it should be replaced. The need to change filters varies widely among users.
Where can I order replacement eartips, filters, and other accessories?

How do I clean my EarAIDs?
You can clean the earpieces by wiping them with a damp cloth as needed. Do not take the earpieces apart, immerse in water, or clean with harsh chemicals or alcohol.
How long do the batteries last?
#10 hearing aid batteries tend to last about 10-14 Days after the tab is removed, based on amount of use. Do not remove the battery tabs until ready to use EarAID earplugs, because zinc air batteries may self-discharge in about 4 weeks whether they are used or not. Discharge rate varies with temperature and humidity. After a tab is removed, it may take a few seconds for air to enter the vent holes and activate the battery. Remember, you can keep your EarAID in the OFF setting when not in use to help prolong battery life. It is recommended that you always have spare batteries on hand.
Where can I find batteries?
Each device uses one #10 battery, a very commonly used hearing aid battery. #10 batteries are easy to find in pharmacies or super centers, and may be ordered at forwardscience.com.
Does battery life depend on the mode used?
Yes. The battery life will be maintained while in the "OFF" setting and will deplete while in the "ON" 15dB-mode. Make sure to allow 30 seconds of acclimation time when placing a fresh battery in your EarAID.
Will I hear distortion in these earplugs?
Probably not. Peak sound pressure levels above 120 dB are reduced to safe levels by the output limitation of the circuit. Because these bursts are so short – on the order of a few milliseconds – the transients are safe. Since reduction is essentially instantaneous, hearing is protected from intense transients. The nearly instantaneous recovery time of the circuit means no loss of fidelity. Ongoing sounds are natural, so you are never "off the air" with these ear plugs for noise reducing.
What is "level-dependent attenuation?"
EarAID circuitry automatically changes output levels as sound input levels change. Hearing is natural, as if nothing is in the ears, until sound exceeds safe levels. As sound levels increase, earplugs gradually provide up to 15-dB sound reduction. Natural hearing is restored when sound returns to safe levels.
How can I test my earpiece to see if it's working?
Turn your EarAID in the "OFF" position where you should notice a significant muffling of sound. Turn your unit back “ON" and after several seconds you should notice sounds come to life and have clarity. This confirms the EarAID is working.
Why does my own voice sometimes sound boomy or hollow?
When eartips do not seal deeply in the ear canal, your voice may sound strange to you. This is known as the occlusion effect, which is caused by sound transmission into the ear from vibration of the ear canal wall when the ear is closed off (occluded) by an eartip. Vibration comes from sound pressure developed in the back of the mouth. The occlusion effect is most commonly caused by vibration from a person’s own voice, especially from speaking the sounds “ee” and “oo,” or from playing a brass or woodwind musical instrument. The occlusion effect is worst when there is a shallow insertion of the eartip. Deeply-sealed eartips reduce the occlusion effect. If this happens consistently, try using other eartips provided with EarAID earplugs to reduce vibration by achieving a better seal.
Why can I still hear sounds while wearing EarAID?
Similar to the effects of local anesthesia, you will still hear sounds, but the ones that are too loud are automatically being reduced by the electronic circuitry in EarAID to a safer level.
What is that funny ticking sound I hear in my earplugs?
That sound is called LOBAT™ a special feature that warns you when a battery is at the end of life. The performance of the earplug does not change when that sound is present, and you usually have enough warning that you can change the battery at a convenient time.
Does my EarAID have a warranty?
EarAID comes with a 1-year warranty from time of purchase.
Is there a return policy?
Due to the personal nature of the earpieces, there are no returns once the package has been unsealed.
How long do they last?
Similar to loupes, as long as they are taken care of and stored in a case, they will last years.
I found something cheaper online that looks the same, how is your product different?
EarAID has a custom, patented circuit which was designed for the needs of the dental environment and the circuit is unique to our product. Other products on the market have amplification features, which is the exact opposite of what we want in the dental environment. Also, the EarAID “off” mode ensures that our battery life/use is higher than other products.
Can I use EarAID with our inner-office communication headset?
No. Only one device can fit in your ear at a time and EarAID is most effective when worn in both ears at the same time.
Is EarAID an FDA cleared device?
Yes. EarAID is an FDA cleared, Class I device.
