A Contralateral Routing of Sound (CROS) hearing aid is a type of hearing device that is used to treat unilateral hearing loss (single sided hearing loss). It takes sound from the ear with poor hearing sensitivity and transmits the sounds to the better hearing ear. As a result, the CROS transmitter device is not a full hearing aid. It has microphones and a computer processing chip, but no speaker. It will therefore be transmitting the sound wirelessly to a receiving hearing aid on the better ear. This type of set-up allows a patient to have access to sound from both sides of their head which aids in volume, clarity, and sound localization.
What is a Bi-CROS System?
A Bi-CROS system is very similar to the CROS system. A patient would still be wearing two devices, however, the CROS transmitter is paired with an active hearing aid providing amplification. A Bi-CROS system is used when someone has an asymmetrical hearing loss, that is a hearing loss in both ears but with one ear better than the other.
Again, the CROS device works as a transmitter which captures the sound from the bad side and transmits it to the hearing aid on the better side. The hearing aid on the better side delivers the sound from the worst ear and amplifies the sound from the better hearing ear as well.
Who is a Candidate for a CROS or Bi-CROS System?
Individuals with either asymmetric hearing loss or single-sided deafness may be a candidate for a CROS or Bi-CROS system. To inquire whether or not this non-surgical option would work for you, give us a call at 904-399-0350 to make an appointment!
1. During an appointment with your audiologist, expect a thorough assessment to determine the severity of your hearing loss and a detailed discussion about your lifestyle, hearing priorities, and budget to help determine what hearing aids are best for you.
2. Expect an adjustment period when you first begin to wear hearing aids. Hearing loss typically occurs over time, and it can take time for your brain to become accustomed to all the sounds you are now hearing again. The world is a very noisy place and you may notice sounds you didn’t realize you were missing such as your footsteps when walking, running water from the faucet & the quiet hum of the refrigerator. After wearing the hearing aids for a week or two, all of those ambient sounds will become less prominent to you. The more you wear hearing aids, the quicker you will adjust!
3. Expect them to “whistle” as you put them in your ears. Once they are in your ears, the whistling should stop.
4. Expect to take care of your hearing aids! The better care that is taken of them, the longer they will last. It is as simple as routine nightly cleaning. Wiping them down with a tissue every night will go a long way!
5. Expect a new technology to be developed every couple of years. You can speak with your audiologist to determine if new technology would be beneficial for you. Just as any other electronic device, they do not last forever and will eventually wear out.
Purchasing hearing aids is a big adjustment to your life but with these few pointers to get you started, you are on your way to better hearing!
All hearing aids require a power source, but many modern hearing aids have the option of either a disposable or rechargeable battery. Which option is the best for you?
Benefits of Rechargeable Batteries: 1. Convenient – Instead of having to frequently repurchase batteries over the lifespan of the hearing aid, you simply charge the hearing aid at night while you sleep. The hearing aid then has battery power for up to 30 hours on a single charge. The internal battery can be charged thousands of times before needing replacement. 2. Easy to Use – Disposable hearing aid batteries are very small and can be difficult to change for some people. Rechargeable hearing aids easily pop into a charger, so there is no fumbling with small pieces. 3. Environmentally Friendly – Given that most disposable hearing aid batteries last about 5-7 days, you will ultimately throw away hundreds of batteries over the lifespan of hearing aids if you use that option. Although hearing aid batteries can be recycled, disposable batteries create much more waste over the lifespan of a hearing aid compared to 2 rechargeable batteries.
Benefits of Disposable Batteries: 1. More portable – Disposable batteries are much easier to take on the go, since you don’t have to pack the charger with a power cord. A pack of disposable batteries is small enough to easily fit in a pocket or wallet. 2. Little downtime – When disposable batteries die, it’s as simple as changing to a new battery in a matter of seconds to power your hearing aids again. When the charge dies on rechargeable hearing aids, it typically takes a couple of hours for the hearing aids to fully recharge, which is especially inconvenient if you don’t have your charger with you. 3. Different hearing aid style options – Certain styles of hearing aids, such as tiny invisible in the ear hearing aids, are only able to be powered by disposable batteries. Other types of hearing aids, such as behind the ear styles, typically have the option of either rechargeable or disposable batteries.
The best hearing aid battery option for you is a matter of lifestyle and personal preference. An audiologist can help you decide what the best choice is to fit your needs.
Many newer hearing aids on the market are Bluetooth compatible and are able to wirelessly connect to both iPhone and Android devices. Patients with Bluetooth-enabled hearing aids enjoy the convenience of streaming phone calls and listening to music/tinnitus maskers from their phones directly to their hearing aids, all the while being able to use their phone as a remote control. But with great convenience comes the occasional annoyance when connections drop out.
If this happens, there are a few things you can do to fix the connection. Here are a few ways you can troubleshoot:
Have you downloaded and installed the latest version of software for your cell phone?
It is important to regularly download and install software updates provided by the cell phone manufacturer. These updates protect your device from viruses and hacking, as well as improve the device’s operation.
Note that a software update may require you to completely switch off the phone for a minute before switching it back on.
Have you downloaded and installed the latest version of software for the app?
If your phone has had a software update, check to see whether your apps also require updating. Occasionally, an update to the device will require an update to the app as well.
Did your hearing aids lose its Bluetooth pairing?
It is possible that you can fix Bluetooth streaming issues by re-pairing your devices in either the Bluetooth or Accessibility screen in your phone’s General Settings.
Remember to turn the hearing aids off and on and place them within a few inches of the phone before re-pairing.
If you are still having Bluetooth issues, we encourage you to come to our Walk-In Clinic (Tuesdays 10:00am – 11:30am and Thursdays 1:00pm – 2:30pm) at the Hearing Center for help troubleshooting your connection.
After you have had a complete audiological evaluation, are fit with the right hearing devices, and your devices have been personalized for your needs, it is important to know what accessories are available to you. Hearing aid accessories can help optimize the performance of the devices and even make them more convenient to use.
Battery Chargers Traditionally, hearing aids have been powered by disposable batteries which need to be replaced every five to ten days depending on the size of the battery. Rechargeable devices are now available, making wearing the device more convenient to wear. The need to change small batteries and have additional batteries on hand is eliminated. This can be very helpful for those who have visual or dexterity issues and it’s also environmentally friendly!
Bluetooth and Streaming Capabilities Many of today’s hearing aids are Bluetooth compatible, meaning they can easily pair to your cell phone and other wireless devices. This enables the user to stream phone calls, music, and other audio sources from the device, hands free, directly to the hearing aids, and allows the user to hear clearly from their hearing aids without interference or hearing unwanted sounds. An app can also be downloaded onto smartphones and tablets to gives access for the individual wearing the devices to control the hearing aids via a remote control.
Another helpful accessory is the television adapter. These adapters allow the user to stream audio from their television directly into their hearing aids, again avoiding interference from unwanted sounds. It also allows the user to control the volume and sound quality without affecting others who may be watching television with them.
Remote Microphones Although many hearing aids today have the ability to help us hear better when background noise is present, some hearing aid users still find these situations challenging. Remote microphones can help resolve this issue by streaming the conversation directly to the hearing aids, helping to eliminate background noise. Remote microphones can be used personally, meaning one speaker wears a device, or in a group where the microphone can be placed in the center of a table.
Dehumidifiers Moisture can affect the performance and function of your devices. Using a dehumidifier, often referred to as a dry aid kit, reduces the amount of moisture collected inside your hearing aid. This is especially true if you live in a humid climate or are exposed to moisture frequently. Dehumidifiers can be electric or non-electric. If your hearing aids are rechargeable, the charging system often includes the dehumidifier, eliminating the need to have a separate accessory.
Having the appropriate cleaning tools to maintain your devices is also important. The use of small brushes, cleaning clothes, cases and other tools will help clean and protect your hearing aids. There are accessories with clips that enable you to participate in sports or physical activities while keeping devices clean, dry, and prevent them from falling out.
Today, there are numerous advertisements in magazines and on television for products that will enhance your hearing. Although many of these devices may look like hearing aids, they typically are not. These devices are called “amplifiers” or “personal sound amplification products (PSAPs)”. Although PSAPs have been around for many years, new age marketing techniques have made them more readily available to consumers.
One of the major differences between hearing aids and PSAPs is how they function and how they are programmed. Hearing aids are programmed for each person’s specific hearing loss while PSAPs generally make sound louder. Hearing aids are programmed using sophisticated software after a thorough hearing test is completed. Audiologist and hearing instrument specialists use the results of the hearing test to program each frequency with a specific amount of amplification for the best possible hearing outcomes. A person may, and typically does, need different amounts of amplification at various pitches or frequencies. On the contrary, a PSAP turns everything up globally, just like increasing the volume on the television. For many people, this results in some pitches being WAY too loud. An additional benefit to hearing aids is that the technology does much more that just “turn certain pitches louder”. There are features such as background noise reduction, Bluetooth connectivity, and maximum output limits; all features for maximum benefit.

Did you that Ronald Reagan was the first President to wear hearing aids while he was in office? He was 72 years old and was fit with a device that was considered “barely visible”. According to the famous article from the New York Times in September of 1983, President Reagan started losing his hearing after a pistol was fired in close proximity to his right ear. The change in technology and size is what prompted the President’s decision to wear hearing aids and the public announcement. Prior to this, reporters had to speak loudly during interviews, particularly if they were on his right side. Thanks to President Reagan, there was a decrease in the negative stigma towards hearing aids.
President H.W. Bush also was an advocate for those with hearing loss. In 1990, President Bush passed the American Disabilities Act which helped provide assistive listening options in patrons in public venues. Although, he did not wear hearing aids during his presidency, he did after he served.
The second sitting President to be fit with hearing aids was Bill Clinton. He was much younger than President Reagan at age 51. Because he was much younger, he encouraged others in his generation to get their hearing tested. He also shed light on the effects of noise induced hearing loss as he was an avid saxophone player. In 2013, he and his daughter Chelsea volunteered with the Starkey Hearing Foundation in Africa, where nearly 400 people were provided with hearing aids.
As things start warming back up in Jacksonville, it is likely that you will be heading to the beach or pool (or may get caught in bad rainstorms!). Whether you are new to hearing aids or have worn them for years, one thing almost all hearing aid wearers should know is that these highly advanced technological devices can be damaged by too much moisture. Here is what to do if your hearing aids get wet.
1.Don’t panic! Most hearing aids have a special coating to protect them from moisture damage. While this coating isn’t waterproof, it is water-resistant so that small amounts of water such as from perspiration or rain will be repelled. 2. Try to determine how much water damage has occurred. Did you get caught in a rainstorm, or did they fall into the deep end of the pool? Regardless of the amount of water exposure, try your best to remove them from the moisture source right away.
3. Wipe away any visible moisture the best you can with a dry cloth or tissue. If you have a battery door you should open it, remove the battery, and wipe inside the battery compartment as well. If you have rechargeable hearing aids, wipe the outside down as best you can.
4. Use special hearing aid dryers and drying “jars” for hearing aids. Drying jars use moisture-absorbing beads to soak up any water that may have gotten into the hearing aids. Electric dryers plug into a wall outlet and are generally more effective than the jars (although the jars are more portable and don’t require electricity). Sometimes, even your charging case doubles as a de-humidifier.
5. See if they still work. If they are not working, or do not sound as good as they once did, contact your audiologist.
6. Check your warranty. If your hearing aid is relatively new, water damage may be covered under the warranty; ask your provider.This may also a good reason to get an extended warranty. If the damage is severe, the hearing aid may be replaceable using your insurance under loss and damage.
7. Try your best to not accidentally submerge your hearing aids again. Try leaving a note taped to the shower door or inside your beach bag that says, “Take out hearing aids!” is very helpful. Sometimes just a reminder is all that is needed to avoid a sticky situation!
If you wear hearing aids, you’re going to experience whistling, or feedback, at some point in the life of the device. Here we will discuss some common causes of feedback and what you can do about it.
How does hearing aid feedback occur?
Hearing aid feedback occurs when sound that was supposed to go into your ear canal leaves your ear and goes back into the hearing aid microphone for a second time. The sound then gets reamplified, and this causes your hearing aids to whistle. This feedback can happen in different contexts, like when you put your hearing aids on in the morning and take them off in the evening. This is perfectly normal because the hearing aids are reacting to the sound bouncing back from your surroundings.
However, hearing aid feedback could also be a sign that something could be wrong with your hearing aids, or they need to be cleaned. In that case it’s best to consult your hearing care professional.
What causes my hearing aids to whistle and what can I do about it?
Hearing aids come with feedback cancellation systems, but this doesn’t completely safeguard you from feedback. A number of things can cause your hearing aids to whistle. Here are the most common reasons for feedback and how to resolve them.
A poor fit: In general, if your hearing aids are not put properly in your ear, it gives the sound a chance to escape and re-enter the hearing aid microphone. Make sure they are sitting nice and tight in your ear when you put them on in the morning. The shape of your ears can change over time, and if they do, the earmolds can become loose and no longer seal properly. To fix it, you may need to get new earmolds fitted to your ear. Weight gain or weight loss can also affect your ears and the fit of the earmolds.
Too high volume: It can sometimes be tempting to turn up the volume on your hearing aids. But turning it up too loud can force the sound to re-enter your hearing aids, which causes whistling. Turn down your hearing aid volume and avoid the point at which sound gets so loud that it creates feedback.
Too much earwax: If your ear canal is blocked by too much earwax, the sound can’t get through. So instead, sound bounces back into your hearing aids and they start to whistle. It is recommended to get your ears cleaned out regularly by a professional (no Q-Tips!) to avoid this problem.
If you continue to experience problems with hearing aid feedback and can’t figure out the reason, make an appointment to see your hearing aid audiologist for further assistance to address the issue.
