What is Hearing Aids?

Hearing aids are small devices that allow a person to hear better in quiet or noisy environments. They allow the users to listen and communicate with others, and be able to go about their normal activities, even after they have been affected by hearing loss.

What are the Hearing Aids

Hearing aids improve hearing by magnifying sound vibrations that enter the ears. They convert sound that is received through a microphone and amplify it through an ear fitting at the right volume for the level of hearing loss that a person has.

Even as recently as a few decades ago, many who suffered from hearing loss felt embarrassed to wear hearing aids due to their large design that stood out to others. Thankfully now there are many discreet options that are almost impossible to spot.

How do Hearing Aids Work?

Hearing aids are electronic machines that amplify the sounds of your surroundings into your ear so that you can hear them better. With a variety of styles and conformations, there is sure to be one that is most comfortable to you so the key is to keep trying different models until you find one that you love. There are three essential parts to a hearing aid:

  1. Microphone
  2. Amplifier
  3. Reviver

The microphone picks up the sounds and sends them to the amplifier which will make the sounds louder. Lastly, the receiver will send these sounds into your ear. Hearing aids are adjustable so you can control how loud you want the amplifier to go.

Different Types of Hearing Aids

Hearing aid technology has advanced in leaps and bounds over the past century, and today, there are two types of hearing aids commonly found:

Different Types of Hearing Aids

Analog Hearing Aids 

Analog hearing aids first came on to the market in the 60s and 70s but are still used today. They have a microphone that transforms sound into a current, which is then amplified and played through a speaker or receiver. While they are not as advanced as digital hearing aids, analog devices are a cheaper alternative and mean that people who cannot afford expensive aids are still able to obtain assistance with their hearing.

  • Affordable
  • Simple to use
  • Pre-programmed settings

Digital Hearing Aids 

The most advanced technology that we’ve seen in the world of hearing aids has brought us digital devices that are much more comfortable and discreet than any previous designs. They work in a similar way to analog models, but they convert sound waves into numerical codes, and you have more control over how you receive the sounds around you. Digital hearing aids include practical settings and features and are able to analyze your environment to give you the best sound quality.

Digital hearing aids come in a variety of forms to fit the needs of users. You can find:

  • Behind The Ear
  • In The Ear
  • In The Canal
  • Complete In Canal

While hearing aids can function differently, they can also be worn differently. 

Styles of Digital Hearing Aids 

BTE Hearing Aid 

BTE Hearing Aid

BTE or Behind-the-Ear Hearing Aids hooks over the top of the ears of the user, and rests behind the ear. BTE hearing aids remain connected to custom earpieces known as earmolds through a tube. The earmold fits in the ear canal easily. This type of hearing aid has traditionally been the largest type of hearing aid. Some of the newer designs are smaller, streamlined, and barely visible. BTE hearing aids are appropriate for any type of hearing loss, and people of all ages.

Latest Technologies in Hearing Aids

Hearing aids technology is getting developed continuously. More and more new features are getting added to the hearing aids of the present time. We started with analog hearing aids, and now most people prefer to use the digital ones that come with various impressive features. These features have made the lives of the users much easier and more convenient. Some of these special features include-

Rechargeable

Most hearing aids these days come with rechargeable features. Rechargeable batteries are used in those hearing aids. Instead of changing your batteries whenever they run out of power, you will be able to recharge them easily by plugging your hearing aids into the charging station. You will be able to use them all day with a full night’s charge.

Bluetooth

Bluetooth connectivity is another important feature that’s provided by digital hearing aids these days. With the Bluetooth connectivity option, you’ll easily be able to connect your hearing aids with your smartphone. Also, any other electronic device that’s compatible with Bluetooth can be connected with your hearing aids. You will be able to stream anything from those devices to your hearing aids and listen properly. You will also be able to stream phone calls directly to your hearing aids through Bluetooth.

Hearing Aid Battery Options

Two different kinds of batteries are used in hearing aids. They are-

  • Standard Disposable Batteries
  • Rechargeable Batteries

Standard Disposable Batteries

All hearing aids once used to come with these disposable batteries. These batteries are known as “zinc-air batteries”, or “button batteries”. These batteries get activated by ear, so they are kept inactive with a factory-sealed sticker. Once the sticker is peeled off, oxygen interacts with the zinc battery to turn it on. 

These batteries remain stable for a maximum of three years when stored in a dry room, and at room temperature. After they run out of power, you will need to dispose of them and get a new battery for your hearing aid.

Rechargeable Batteries

These days many of the good-quality hearing aid models come with rechargeable lithium-ion batteries. These batteries have become way more popular than disposable batteries, as you can use a battery for a long time just by recharging it when the power goes down. You’ll need to charge these batteries to keep them functional, just like smartphones work. Most hearing aids with rechargeable batteries come with a docking station that’s really easy to use. Each night before going to bed, just take out your hearing aids and plug them into the charger before going to bed. The battery life of rechargeable hearing aids varies from device to device.

Should I Need a Hearing Aid?

Hearing aids are the most effective treatment method for people that are suffering from permanent hearing loss to some degree. When hearing loss problems occur due to damages in the hearing cells of the inner ear, they can’t be cured or reversed. They are known as permanent or sensorineural hearing loss. As these hearing loss problems can’t be treated completely, people need to take measures that can help them listen to sounds better, and take care of their hearing health. Hearing aids are the best option for that.

Hearing aids help a person with hearing loss to listen better by amplifying sounds for them. At the same time, hearing aids keep the hearing health of the person from further deteriorating. Overall, hearing aids help a person with hearing loss to get on with their normal lives. So, if you get diagnosed with a permanent type of hearing loss, you should resort to using hearing aids based on your hearing needs. Your audiologist will prescribe the right kind of hearing aids to you.

How to Get A hearing Aid?

If you haven't already, it's best to consult an ear, nose, and throat doctor (ENT) to assess your hearing loss so they can find out what caused it and what the severity is. You can find this specialty doctor by searching the internet or asking your regular general practice doctor for a recommendation. Consulting with and ENT along with an audiologist will give you enough information to find the hearing aid best suited for your needs.

Frequently Asked Questions

Q. What is the difference between deafness and hearing loss/impairment?
Ans: Deafness refers to the profound loss of hearing ability in one or both ears with little to no hearing at all. Whereas, hearing impairment is a broad term that can be defined if one has a problem or suffer damage to one or both ears. It also refers to a diminishing ability to experience sound like most others. Deafness itself is a form of hearing impairment.

Q. At what point do you need a hearing aid?
Ans: People with normal hearing can hear sounds less than 25 decibels (dB). If the softest sounds you can hear are 30 dB or louder, you may be missing a significant amount of what is said to you and are probably a candidate for a hearing aid. It's important to note that hearing aids are only amplifiers.

Q. What percentage of hearing loss qualifies for disability?
Ans: If you have a word recognition score of 60% or less using the Hearing in Noise Test, then it qualifies as a disability. 

Q. Is it okay to wear one hearing aid?
Ans: It's completely okay to wear one hearing aid if you have mild hearing loss in one ear. But make sure to check-up regularly whether your good ear is still hearing well or not.
