Hearing loss affects a lot of people. Hearing loss, whether mild, moderate, or severe, has a significant impact on many aspects of life, from job to relationships and emotional well-being. Hearing aids can make a significant difference, especially if you choose the proper ones and receive assistance with their use. Hearing loss is often treated with hearing aids, and hearing aids can help you hear better, even if they aren't a cure.
What is a hearing aid?
Hearing aids are small electronic devices that can be individually tailored to suit various forms of hearing loss. It increases the volume of some sounds so that a person with hearing loss can listen, speak, and fully engage in daily activities. In both quiet and noisy environments, a hearing aid can help people hear better. However, just 1 in 5 persons who could benefit from them.
How do hearing aids work?
All hearing aids have -
A microphone to pick up sound;
A way to make sound louder, called an amplifier;
The louder noises are sent to your ear via a receiver.
An on/off switch; and
Batteries.
The way hearing aid works -
1. A microphone picks up the sound and converts it into an electrical/digital signal.
2. An amplifier increases the strength of that signal. Advanced signal processing is used in more smart technology to modify the signal.
3. It is converted back into sound and sent to the inner ear through a receiver/speaker. The brain interprets the sound as speech and “hears” it.
To power the hearing aid and enable amplification, a battery is required.
How do hearing aids help to hear?
Hearing loss can occur at any age. Hearing loss is usually caused by noise pollution, virus-bacterial-fungal infections. Then daily life can be made easier by using hearing aids.
Patients who have damage to their inner ear or the nerve that connects the ear to the brain typically use them. Disease, aging, loud noises, and medications can all cause damage.
Conductive hearing loss is a type of hearing loss caused by abnormalities with the ear canal, eardrum, or middle ear. The majority of the time, surgery or other medical assistance can help. However, those solutions aren't suitable for everyone. A hearing aid may be beneficial if you have an open ear canal and a normal external ear.
Some people are born without an external ear or ear canal, making it impossible for them to utilize a traditional hearing aid. Instead, individuals might be able to employ a device that sends sound to their inner ear via their skull's bone.
Types and Styles of Hearing Aids
Hearing aids differ significantly in terms of price, size, special features, and how they're inserted into your ear.
Types:
Hearing aids are divided into two categories:
Analog Hearing Aids:
Sound waves are converted into electrical impulses, which are subsequently amplified by analog hearing aids. They're typically less priced and have straightforward volume settings.
Digital Hearing Aids :
Digital hearing aids enhance sound waves by converting them into numerical codes akin to computer codes. The code contains information on the pitch and volume of a sound, as well as its direction. This makes it easier to tailor the sound to your requirements. The majority of them will adapt themselves automatically. Although this sort of hearing aid is more expensive than an analog hearing aid, the results are far superior. They're also more powerful and smaller.
Styles:
Hearing aids can be divided into four styles. They differ in terms of size, placement in or on the ear, and the degree to which they amplify sound.
The following are some of the most popular hearing aid styles –
a) Behind the ear (BTE) :
The most common type of hearing aid is behind the ear (BTE). Hearing aids that fit behind your ear are known as behind the ear (BTE). The sound is directed to the ear through a plastic ear mold that fits within the outer ear. A Mini BTE, for example, is completely behind your ear and has a thin tube that passes into your ear canal. This prevents earwax buildup and ensures that your own speech is heard clearly. BTEs can help with hearing loss ranging from mild to severe, but they aren't for everyone.
b) in-the-ear (ITE) :
Hearing aids that fit entirely into your outer ear are known as in-the-ear (ITE). The electronics are contained in a hard plastic casing. They're ideal for those with medium to severe hearing loss, but they're not as effective for kids whose ears are still maturing.
c) Canal Hearing Aid :
A hearing aid that fits in your ear canal is known as an in-the-canal (ITC) hearing aid. Canal hearing aids are smaller and harder to see since they fit into your ear canal. A completely-in-canal (CIC) hearing aid is smaller and almost invisible in the ear. Both ITC and CIC hearing aids can benefit those with mild to moderate hearing loss. However, due of their size, they can be more difficult to adjust and remove. It's practically impossible for others to notice an invisible-in-canal (IIC) aid. It could be something you wear every day or something you wear for several months at a time. These types of hearing aid aren’t recommended for youngsters or adults who have difficulty using small gadgets.
d) Body worn hearing aids :
Hearing aids that are worn on the body are made consisting of a little box that is connected to earphones. The box can be fastened to your clothing or carried in your pocket. If you have severe hearing loss and require a powerful hearing aid, or if you find the settings on smaller hearing aids difficult to use, This sort of hearing aid might be your best option.
Caring for Your Hearing Aid
The life of your hearing aid can be extended with proper maintenance and care. Here are some tips to keep in mind.
- Clean your hearing aids according to the instruction. A hearing aid might be harmed by earwax or ear discharge.
- Heat, moisture, hair products, kids, and pets should all be kept away from them.
- Turn the device off, when you're not using.
- Dead batteries should be replaced as soon as possible. Hearing aid batteries can last anything from a few days to a few weeks. The type of battery used, the power requirements of the hearing aid, and the frequency with which it is used determine the battery life.
- Hearing aids can last anywhere between three and six years in most cases. If your hearing loss worsens, you might need a new one sooner. Because they may be configured for a broader spectrum of hearing loss.
