Struggling to catch every conversation or asking others to repeat themselves frequently, but hesitant to wear a visible device in public? You are not alone! We understand that the very thought of wearing a visible device on your ear may feel uncomfortable, especially when you are concerned about cosmetic preferences or social stigma. Seniors, especially, are reluctant to wear hearing aids, as they often fail to accept that they have any hearing difficulty in the first place. This further delays hearing loss treatment, making the problem worsen over time. As a result, hearing loss becomes more obvious and affects one’s personal relationships.
So, here’s good news! Hearing aids have come a long way from the traditional bulky devices to today’s smart and more discreet digital hearing aids. Today’s hearing devices are not only smaller in size but also more technologically advanced, designed to provide a more natural listening experience. In this blog, you will learn about hearing aids, the benefits of wearing them, and how hearing aids work to address one’s unique hearing needs.
What is a Hearing Aid?
A hearing aid is an electronic medical device that amplifies sound for individuals suffering from hearing loss. While hearing aids cannot restore one’s natural hearing abilities, they can help people hear better in different listening environments, enabling them to communicate more confidently and effectively. Therefore, hearing aids are primarily designed to improve the hearing and speech comprehension of individuals with hearing loss.
How Do Hearing Aids Work?
A hearing aid has three basic components: a microphone, an amplifier, and a speaker. The microphone picks up the sounds, converts them into electrical signals, and sends them to the amplifier. The amplifier then increases the intensity or power of the converted signals and transmits them to the speaker. Finally, the speaker delivers the amplified sounds to the person’s ear, enabling them to hear the sound louder. Speaking of loudness, it needs to be mentioned that not all sounds would sound natural when they are made ‘louder’. Learn more about it in the following section.
Do All Hearing Aids Work the Same Way?
No, not all hearing aids would function similarly, as they differ in technology. Suppose a hearing aid user is having a conversation with someone in a noisy environment, such as a marketplace or a restaurant; they would want to focus only on the speech. That’s when digital hearing aids come to the rescue, as they comprise advanced noise reduction algorithms to distinguish speech from noise, amplifying only what’s important.
So, hearing aids can be classified into two types based on technology: analogue and digital. While analogue hearing aids amplify every sound equally, without differentiating between speech and noise, digital hearing aids, on the other hand, are designed to filter out the unwanted background noises to amplify only speech sounds, making conversations easier and more comfortable. Therefore, digital hearing aids are a boon for people with active lifestyles, thanks to modern hearing aid technology, such as noise reduction, directional microphones, feedback cancellation, and automatic speech enhancement.
How Can Hearing Aids Help?
Hearing devices can treat any type of hearing loss, but they are particularly helpful in treating sensorineural hearing loss, which is irreversible and permanent. Sensorineural hearing loss is caused by damage to the sensory hair cells of the inner ear (cochlea). It may result from factors like ageing, overexposure to noise (sound-induced hearing loss), underlying causes of some diseases, or certain medications.
As mentioned earlier, a hearing aid magnifies the external sound vibrations as they enter through the ear canal. The surviving hair cells (that are not yet damaged) pick up the larger sound vibrations and convert them into neural signals, which are then transmitted to the brain via the auditory nerve. The brain processes the sounds and helps us comprehend them, and that’s when we actually ‘hear’ the sound.
However, when a majority of the hair cells are damaged (leading to severe to profound hearing loss), hearing aids may not work effectively. In such critical situations, the audiologist may recommend alternative hearing loss treatments, such as cochlear implants. Therefore, it’s highly recommended that individuals get regular hearing checkups, especially after 60 years of age, and one should never ignore the warning signs of hearing loss. It’s also important to remember that hearing loss can affect people of all ages. Therefore, early intervention and prompt hearing loss treatment can make a big difference, ensuring optimal hearing health in the years to come.
Key Takeaway
To conclude, hearing aids are sound amplification devices that help individuals with hearing loss hear and communicate better. Get a thorough hearing evaluation from a qualified audiologist as the first step towards better hearing. After the professional assesses your hearing profile, they will recommend the most suitable hearing solution. Discuss your hearing aid style preference, lifestyle, hearing challenges, and budget to help your audiologist find the right fit for you.
