Hearing loss has become a common problem in todayโs generation. Hearing loss means difficulty in the hearing pathway. It makes us unable to detect speech or sound and even causes issues when hearing normal sounds. Hearing aids are one of the devices that become instrumental in dealing with this issue.
Doctors often prescribe hearing aids to certain patients to help them manage their hearing issues. Though they do not cure or heal the hearing pathway, they usually give people a way to cope with their daily work and routine.
In this article, we shall discuss hearing loss, how hearing aids came into the picture, their broad scope, and, most importantly, whether cheap hearing aids are worth buying. In upcoming sections, we will learn more about the ailment.
1. Hearing Loss
According to the World Health Organization, more than 1.5 billion people suffer from this ailment. It accounts for 20% of the crowd globally. By 2050, the numbers will be estimated to cross 700 million globally. This comprises 30% from the older age people group and around 34 million from the children age group.
According to the medical world, hearing loss means partial or complete issues with hearing every day or any speech in one or both ears. The severity can range from simple, mild to very severe. As we discussed, it can damage one ear or both ears. 20dB is the safe hearing level on average1.
1.1. Types of Hearing Loss
Depending upon the causes and age groups, hearing loss can be categorized into three types. It includes
- Sensorineural hearing loss
- conductive hearing loss
- Mixed hearing loss.
Sensorineural hearing loss2 is the most common type of hearing loss. It usually happens suddenly. Causes include medications, exposure to loud noises, or injury to the inner ear. Damage to the walls of the inner ear is the primary cause. One is advised to consult an ENT doctor as soon as possible because prolonged conditions without treatment will make it worse.
The following type is conductive hearing loss. This is because the middle ear canal cannot carry sound waves to the inner ear canal. Ear wax or any fluid may block the middle ear channel, causing blockage. It is more common in children3 as they are active, and there are chances of inserting foreign objects. Ear infections can also contribute to conductive hearing loss.
Mixed hearing loss includes sensorineural and conductive4. The hearing test in a hearing clinic is necessary to identify the type of loss and act accordingly. Doctors often prescribe hearing aids after diagnosis.
1.2. Causes of Hearing Loss
The most common cause is inner wall damage. The inner ears comprise the cochlea and nerve endings that pass impulses to the brain. Damage to these parts prevents the impulse or wave from passing and creates obstacles in identifying the sound wave.
Depositions of dust or earwax in the middle ear channel cause blockage. This prevents sound waves from passing onto the inner ears for transmission. Removing earwax is one simple process to tackle this cause.
Inflammation or complete damage of the eardrum is one of the causes. Sudden loud noises or sudden alteration in pressure become the primary reason.
Aging or Age-related hearing loss is one of the shared insights we think about while addressing hearing loss. As we grow older, the membrane of the inner ear ruptures5 and causes damage.
Loud noises are one of the common causes nowadays. They affect all age groups, especially children, who are more accustomed to them. Prolonged exposure to party music or the habit of using earphones or headphones strengthens the wavesโ vibration. This builds up extra pressure on the walls, and eventually, the walls rupture.
Loud noises are not only related to music, but factory employees are also on alert. Often, noise pollution on roads may cause hearing ailments in local vendors. Construction site noises are also included in this category.
1.3. Symptoms of Hearing Loss
- Troubling in hearing or identifying words or sentences in public
- Turning up the volume of devices often
- Asking others to speak slowly and loudly more often
- Background noises interrupt you while talking
- Speech delay in children is also a warning of hearing ailment
- The feeling of fluidness in the ear
- Having earaches more often
- Facing difficulties in balancing your body
- Facing dizziness more often
1.4. Ways to Prevent Hearing Loss
- Turn down the volume of devices when there is no requirement
- Protect your ears in factories by using cotton or earplugs
- Avoid noisy places and often take a break from a noisy environment.
- We also need to be cautious and should not create noise. We should avoid shouting, which results in noise.
- Noise reduction should be done as much as possible. Unnecessary blowing of horns or usage of silencers should be avoided. Construction sites should work within the time frame.
- One should not spend prolonged hours over phone calls.
- Pregnant women, infants, and children should take precautions more precisely.
2. Hearing Aids
Hearing aids are devices prescribed by doctors to deal with patients with hearing difficulties. It is done after a proper hearing test and by a qualified medical practitioner. It is helpful in case of partial ear deafness, conductive hearing loss, and so on. Hearing aids are portable small personal sound amplification products that amplify the incoming sound. It is designed so that it does not interfere with one daily routine.
Hearing aids are divided into three categories and can be used for purposes other than medical diagnosis. Prescription hearing aids are used to treat hearing loss. However, some are also used for personal amplification, especially for specific activities or environments.
The following section will clarify the types of hearing based on usage and causes.
2.1. Types of Hearing Aids
2.1.1. Behind The Ear (BTE)
Behind the ear (BTE) comprises a rigid plastic cover worn behind the ear. The main components remain behind and fit in the outer region. A new BTE device6 may have a narrow channel leading to the middle ear canal. It can be termed as open-fitted. It can be used to deal with ear wax, and such devices are used to treat mild hearing loss.
2.1.2. In The Ear (ITE)
In the ear (ITE) is the next type. As the name suggests, it is entirely fitted in the outer region of the ear. Children shouldnโt wear it, and it is used to treat mild to profound hearing loss.
It has certain additional features, like the presence of telecoil, which allows for a more precise transmission of sound in public. Sound is passed not directly to the microphone but through the coils, which helps the user have fewer interrupted discussions over telecalls.
2.1.3. Receivers In The Ear (RITE)
Receivers in the ear (RITE) are similar to BTE products. They also sit behind the ear. It has a narrow, tiny tube or canal leading to the middle ear. It is more susceptible to earwax, though. It has a manual control system and better volume control.
2.1.4. Completely In The Canal (CIC)
The next type is the completely-in-the-canal 7(CIC) hearing aid. These tiny devices can be fitted partially in the outer ear. They are challenging to use and handle and, hence, less preferable.
2.1.5. CROS/BICROS
CROS/BICROS are hearing aids used to treat single-sided deafness8. In this case, one wears the transmitter in the deaf ear and the speaker and microphone in the good ear. When sound waves come in, the transmitter shifts them to the excellent ear, where they are amplified and heard. BICROS is similar but used when one has lost the hearing capacity in the good ears, too.
Tailor Hearing Aids to Loss Type
Iโve learned that understanding the differences between sensorineural, conductive, and mixed hearing loss is fundamental in selecting the most effective hearing aid.
Sensorineural hearing loss, which results from damage to the inner ear or the auditory nerve, is prevalent among older adults. It often leads to difficulties in understanding speech, especially against background noise.
For this type, digital hearing aids that can be finely tuned to amplify specific frequencies where the loss is greatest show considerable effectiveness. They also often feature noise-reduction technologies crucial for seniors who struggle in social settings.
Conductive hearing loss, on the other hand, occurs when sound is blocked before it reaches the inner ear. For seniors with this type, hearing aids that primarily amplify sound can provide significant benefits.
However, those with mixed hearing loss require a more versatile approach, needing features tailored to both amplification and clarity.
Thus, understanding the specific type of hearing loss not only influences the selection of hearing aids but ensures that seniors receive support that directly addresses their unique auditory challenges, ultimately improving their communication and quality of life.

2.2. Components of Hearing Aids
The most significant part of the hearing aids comprises the body. The device is structured so that it sits behind the ear pinna. The whole device can be divided into internal and external components.
2.2.1. Internal Components
- Microphone- This part of the hearing aid receives sound waves and passes onto an amplifier for amplification.
- Hearing amplification- It is an essential component as it decides the intensity of the sound wave that needs to be amplified.
- Power Source- The other component is differentiated based on models. It can be rechargeable or disposable.
- Telecoil- A telecoil is an additional feature in some that helps in a public setting sound experience.
2.2.2. External Components
- Body CoveringโThis is the outermost part of the device, which is noticeable. It is one of the designed portions and is often marketized based on design.
- SwitchโA button or switch helps turn the volume up and down. In the latest ones, it can be the control point for the different controls.
- Wireโ It runs through the body and is used to transmit signals.
- Speakerโ It converts electrical signals to sound waves that users hear.
- EarmoldsโThese are some of the additional features. They prevent sound waves from leaking or escaping and make them more audible. They are fitted in the cochlea region.
- Domes- A dome is an advanced feature for old-age usersโ devices. Cleaning is required regularly. It is a small mushroom and silicon-made.
Amplify or Process: Matching Aid to Loss
Working in insurance, Iโve often encountered clients with hearing loss, often engaging in discussions about hearing aid selection for the type of hearing loss experienced.
Conductive hearing loss, resulting from issues in the outer or middle ear such as infections or blockages, often requires hearing aids designed to amplify sounds, making them louder and clearer to the user.
Then thereโs sensorineural hearing loss, typically due to inner ear or nerve damage, that may be age-related or noise-induced. Hearing aids equipped with sophisticated features like digital signal processing are preferred for this type.
For mixed hearing loss, individuals might need hearing aids customized to address both conditions effectively.

2.3. How Do Hearing Aids Work?
All hearing aids have a common principle in their work. The primary criterion is to amplify the environmental sound to hear adequately. It is equipped with many components, as discussed above. The sound waves are collected and passed on to convert to electrical signals. The signals are amplified and then again reconverted into sound waves. The sound waves are passed onto the inner ears to the brain for analysis.
To be very precise, the microphone receives sound waves and converts them. The amplifier amplifies the impulses. Finally, the speaker transfers the amplified intense sound to the ears.
The work is done digitally. Nowadays, designers have come up with many ideas, such as small portable or less noticeable hearing aids, to make them more user-friendly and comfortable. There have been some apps that allow users to control their hearing aids.
2.4. Hearing Aids Maintenance
Clean it regularly with a dry cloth. Some branded hearing devices come with a cleaning kit and a manual, which it is recommended to follow.
Often, maximum hearing aids work on batteries. Remove the battery before keeping it aside at night. This will increase the shelf life of the medical devices and can encourage cleaning of the minute parts.
It is recommended to consult or have an appointment every six months with the hearing professionals. They will check the efficiency of the device and other requirements.
It is preferable to use up-to-date technologies when medical devices are counted. Often, the latest technology imparts more comfort in using and controlling the device.
If any component is damaged or malfunctioning, it should be changed or replaced immediately. Otherwise, the machine may not be as efficient.
Caring for Your Hearing Aids
When you think about it, hearing aids are like tiny computers for your ears. Theyโre packed with advanced technology designed to enhance your hearing experience.
By cleaning them regularly and following the manufacturerโs guidelines for care, youโre essentially giving your hearing aids the love and attention they need to keep doing their job effectively.

3. The Average Cost of Hearing Aids
The cost of hearing aids does not include the deviceโs price alone. It includes fitting charges, follow-up treatment charges, maintenance charges, battery changing charges, and so on. The range of hearing aids varies based on the technology. The professional one ranges between $1000 and $4000.
This price can also vary depending on the usage. For mild or less severe hearing loss, one does not need follow-up protocol, so his/her cost might decrease. Personal amplification products are not included in this range and are commonly less priced. Some popular model and their prices are as follows:
- Starkey Muse โ $1450
- Oticon OPN โ $2450
- Phonak Audio B โ $1350
Notably, 40% of Americans take up insurance facilities to cover their hearing aid costs. The insurance generally covers 85% of the price, consists of medicare advantage plans, and is responsible for its maintenance over the years.
Weigh Durability Against After-Sales Support
One crucial factor to consider when looking at cheaper hearing aids is their durability and the availability of after-sales support and service.
Inexpensive hearing aids might not be as durable or reliable as their higher-priced counterparts, potentially leading to higher maintenance costs or the need for replacements sooner than anticipated.ย
Additionally, after-sales support, such as adjustments, repairs, and regular servicing, plays a significant role in the overall satisfaction and effectiveness of the hearing aid experience.ย
Before making a purchase, individuals should research the manufacturerโs reputation for customer service and read reviews from existing users. Itโs also important to consider oneโs lifestyle and how it may affect the wear and tear on the device.ย
Active individuals or those who work in environments with varying temperatures and humidity levels might find that investing in a more robust, slightly more expensive model will be more cost-effective in the long run.ย
Therefore, weighing the long-term reliability and support against the initial cost savings is essential in making an informed decision that aligns with individual needs and preferences.

3.1. Is it Worth Buying Hearing Devices Online?
Online will give you a discounted price on your hearing aids. However, it may not cover the installation and consultation of the hearing aids. It is an essential aspect, as in offline stores, installation is done according to the needs and comfort of the user. Any difficulty can be approached immediately. But online lacks this facility. Online may also not provide actual authentic products.
So, it is advisable to have such medical devices installed and bought from offline stores. It is also better to ask medical practitioners about this.
4. Differences Between Expensive and Cheap Hearing Aids
As we discussed before, hearing aids can be expensive or cheap. However, we need to know the differences that affect their prices.
4.1. Based on Appearance
Appearance is the first thing that is applied while marketing products. This is the case with hearing aids. Expensive ones have a more aesthetic and so-called cool look. To some extent, a good-looking device will motivate a user to wear it without hesitance.
Conversely, inexpensive hearing aids are not very classy in appearance. People also choose expensive ones owing to the comfort they provide.
4.2. Based on Sound Quality
The second or primary difference is the sound quality between the two categories of devices. Expensive hearing aids have much better quality sound processing systems than cheaper ones.
This is because of the noise-cancellation features of inexpensive hearing aids. One can ignore the surrounding sounds and focus on the conversation.
However, a noise reduction facility does not work in the case of a cheaper one. So, the user may get interrupted by the outside noise and may have to raise the volume more often to hear the conversation.
The sound of wind or any other unwanted sound can be avoided in the expensive ones. So one can have a clear and interruption-free hearing experience, and the severity of the hearing loss wonโt increase.
4.3. Based on Additional Features
The additional features are the last thing that differentiates an expensive one from a cheaper one.
For example, Bluetooth connectivity is available in expensive devices connected to devices like televisions and mobiles, and one can hear speech details. It makes the experience more pleasurable and comfortable for the users.
Some offer tinnitus therapy, which avoids ringing in the ears. The Remote online management we discussed above is found in expensive hearing aids. It prevents physical visits to hearing care providers.
5. Do Cheap Hearing Aids Work?
First, we should be clear about the basic need for hearing aids. One needs to have an uninterrupted hearing experience and good sound quality. But why is there a difference in prices among the hearing aids? It simply means the features make them different.
Cheap hearing aids compromise in certain other aspects, like poor quality. Buying online to get the product at a cheaper rate will have some negative aspects.
- Cheaper ones will have compromised material out of which hearing aids are made.
- They are made up of inferior plastics and are not coated well. Parts may not placed well in the devices and may cause malfunctioning.
Subsequently, inexpensive hearing aids may not be long-lasting. They will not have a warranty, either. Sound quality will differ, and the user will face difficulties that sometimes worsen the disease.
Cheap ones may lack noise cancellation facilities and sudden noise cancellations. It may increase the difficulty in hearing as well. Cheap products are often mass-produced, and there is a high chance that you may get a malfunctioning product. They will not work and adapt in different scenarios and will stick to primary, i.e., only amplifying any sound waves coming.
Hence, it is preferable to buy an expensive and quality hearing aid. Proper brands should be explored while purchasing. Some popular brands are Phonak, Oticon, Starkey, Widex, etc. It is also advisable to go for a device with the latest technologies to experience a good hearing experience.
Assess Compatibility with Personal Tech
When considering the purchase of more affordable hearing aids, a crucial factor to weigh is their compatibility with various accessories. This was a lesson I learned firsthand when my grandfather decided to opt for a less expensive model.
He soon found that it didnโt sync well with his smartphone, a feature he highly valued for managing settings and volume control.
This experience highlighted how individual needs and preferences, such as the desire for seamless integration with personal technology, can significantly influence the perceived value of cheaper hearing aids.
Itโs essential to assess how well these devices mesh with your lifestyle, especially if you rely on certain tech integrations for optimal use.
