Behind the Tech: How Does a Hearing Aid Actually Work? | Miracle-Ear

Most hearing aids function in a similar way, but youll see some differences between digital and analog hearing aids. Digital hearing aids are the most common option today.

  • Digital hearing aids: Digital hearing aids convert sounds into digital codes that include information on the pitch, volume and direction of the sound. All this information allows full customization to match your degree of hearing loss.
  • Analog hearing aids: The original hearing aids were analog, meaning they convert sound into electrical rather than digital signals. While this helps amplify sound, it doesn’t amplify particular sounds, meaning users tend to get quite a bit of background noise and feedback.

Selecting A Hearing Aid Provider

Some people who notice theyre having difficulty hearing start with their doctor or an otolaryngologista doctor who specializes in ear, nose, and throat problemsthen get referred to an audiologist.

What should you do? Our hearing expert recommends that you see an audiologist, who can determine whether you might have an underlying medical issue that is causing your hearing loss. They can refer you to a physician if necessary.

The audiologist will conduct tests to assess your hearing aid requirements. They will then match your ability to understand speech in different settings, your listening needs, and more factors to the appropriate technologies. There are many hearing technologies, so it is important to work with your audiologist to decide which will be best for you.

Many audiologists work in private practices , where 29 percent of our survey respondents purchased their aids. Audiologists may also be on staff at wholesale clubs, such as Costco, where 19 percent of respondents purchased aids, or at hearing aid stores owned by manufacturers such as Oticon, Phonak, ReSound, Starkey, and Widex.

Note that some big-box stores often have employees known as hearing aid or hearing-instrument specialists. Their license is typically posted, but its always wise to ask whether youre seeing an audiologist or a hearing aid specialist.

Behind The Ear Hearing Aids

There are three major main types of hearing aid: Behind The Ear , In The Ear and Receiver In Canal. Each has their own set of advantages and disadvantages. If you are thinking of buying a hearing aid, it is worth spending some time thinking about which type would be best for you. Ideally, you should visit an audiologist or aid vendor who will give you a hearing assessment and advice on which aids would be most suitable for you. Modern BTEs are a far cry from traditional hearing aids, today’s behind the ear hearing aids are smaller and more discreet than ever before. This style of hearing device is available in many different shapes and colours and over recent years, they have gotten much smaller than they once were. They are hugely versatile devices and they will fit nearly every hearing loss.

What Questions Should I Ask Before Buying A Hearing Aid

Before you buy a hearing aid, ask your audiologist these important questions:

  • What features would be most useful to me?
  • What is the total cost of the hearing aid? Do the benefits of newer technologies outweigh the higher costs?
  • Is there a trial period to test the hearing aids? What fees are nonrefundable if the aids are returned after the trial period?
  • How long is the warranty? Can it be extended? Does the warranty cover future maintenance and repairs?
  • Can the audiologist make adjustments and provide servicing and minor repairs? Will loaner aids be provided when repairs are needed?
  • What instruction does the audiologist provide?

To Adjust Or Not To Adjust

Some hearing aid styles come pre-adjusted by an audiologist or hearing care professional, whereas others such as online and OTC brands are adjusted manually by the wearer.

If youre interested in a pre-adjusted device for your type of hearing loss, youll need to complete a hearing test with an audiologist, or you can find the best online hearing tests here.

Once your new hearing aid is ordered, the audiologist will use that test to make the necessary adjustments to your device with your specific hearing needs in mind.

Pre-adjusted hearing aids are best for anyone with dexterity issues or difficulty operating smaller devices. However, the more technologically advanced hearing aid styles can be adjusted manually through a smart device such as a cell phone or tablet.

Reprogramming Hearing Aids

Over time, your hearing will fluctuate, and your device will not work as well as it once did. Its advised to have regular check-ups with an audiologist, at least twice a year, to determine if your device requires re-programming.

Age has a significant impact on hearing, where roughly 43.2% of adults aged 70 and up suffer from hearing impairment

Signs that your device needs reprogramming:

  • Discomfort or pain around the ear.
  • Volume fluctuations.

How Hearing Aids Help

A hearing aid is a battery-powered electronic device designed to improve your hearing. Small enough to wear in or behind your ear, they make some sounds louder. They may help you hear better when it’s quiet and when it’s noisy. Hereâs how they work:

  • A microphone picks up sound around you.
  • An amplifier makes the sound louder.
  • A receiver sends these amplified sounds into your ear.

Not everyone with hearing loss can benefit from hearing aids. But only 1 in 5 people who could have improvement wear them. Most of the time, theyâre for people who have damage to their inner ear or the nerve that links the ear with the brain. The damage can come from:

  • Disease
  • Loud noises
  • Medications

Hearing loss thatâs due to problems with the ear canal, eardrum, or middle ear is called conductive hearing loss. Most of the time, surgery or other medical help can make it better. But those options arenât right for everyone. If you have an open ear canal and a relatively normal external ear, a hearing aid may help.

Some people are born without an external ear or ear canal, which means they canât use a typical hearing aid. Instead, they may be able to use a device that sends sound to the inner ear through the bone of their skull.

How Can Hearing Aids Help

How Do Behind The Ear Hearing Aid Work

Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. The damage can occur as a result of disease, aging, or injury from noise or certain medicines.

A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a persons hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective.

It can be fitted with a thin tube and instant tip, which you can see above, or a traditional ear hook, tube and ear mould. It means that people who like BTEs now have a rechargeable option.

Why Is My Hearing Aid Distorted

My hearing aids sound muffled, or my hearing aids sound funny or distorted are common hearing aid complaints. Hearing aid voice distortion can be a muffled sound or a crackling sound.

Solution: Check battery terminals for rust or dirt accumulation. You will notice two shiny strips inside the battery compartment these are the positive and negative terminals which carry the current from the battery to the circuit. If any of them is rusted or has dust coating, it will not send the current efficiently giving rise to distortion. Take a cotton bud or a Q tip and clean the battery terminals.

Low batteries are also one of the reasons please refer to the procedure given above for checking batteries.

Moisture in a hearing aid can cause distortion humidity interferes with the working of the electronic circuit and can distort the speech.

What Is A Behind The Ear Hearing Aid

Behind the ear or BTE hearing aids have a main shell section, an earmold and a connecting tube. The main shell houses all of the electronics and the battery. The BTE model hooks over the top of your ear and rests behind the ear. Traditionally a plastic tube connects the hearing aid to a custom earpiece called an earmold that fits in your ear. More recently many of the hearing aid brands have introduced thin tubing, which connects BTEs to the ear. Thin tubing can be used with a generic dome or a custom tip. Thin tubing is very discreet but it is not suitable for all hearing losses.

Bte Hearing Aids And Assistive Listening Systems

Positioning the shell of a BTE hearing aid behind the ear makes it possible to use larger shells than in-the-ear or receiver-in-canal hearing aids. In turn, this means the hearing aid has space for more hardware than smaller hearing aids, including assistive listening systems such as telecoils, FM systems, and Bluetooth connectivity.

Atelecoilis a small coil of wire wrapped around a tiny metal rod in the BTE hearing aids shell. Telecoils act as antennas, picking up sound transmitted as magnetic signals sent by hearing loops or audio induction loops. A hearing loop is an assisted listening system often used by churches, concert halls, universities, airports, museums, and even taxis. Hearing loops can also transmit sound from some televisions and music systems.

Hearing aids with telecoil capabilities have t-switches so you can switch from the hearing aids microphone to listen to the hearing loop broadcast. Some BTE hearing aids include a microphone/telecoil setting so you can listen to the telecoil and microphone at once, for situations where you want to follow the telecoil signal and converse at the same time.

Bluetooth connectivity is increasingly common in hearing aids. Bluetooth allows you to listen to televisions, computers, music players, and radios through your hearing aid.

Completely In The Canal Hearing Aids

Key features:

  • Ear canal impression used to create a custom fit.
  • Comes in a variety of skin tones and colors.
  • Can sync to smart a device.


  • Smallest and least visible hearing aid.
  • Custom-fit for excellent sound quality.
  • Less sensitive to wind noise.
  • Less feedback from telephone and other interference.


  • No extra features such as volume control or directional microphone.
  • Not for those with profound hearing loss.

As the name suggests, completely-in-the-canal devices fit entirely inside your ear canal for almost invisible wear. These are ideal hearing aids for adults with mild to moderate hearing loss.

Because this device fits deep within the ear canal, removal occurs by tugging on a small string attached to the device. The batteries used for these completely-in-the-canal hearing aids are quite small and do not have a long lifespan.

In general, completely-in-the-canal hearing aids can be difficult to handle and adjust. Still, the nearly invisible style makes it popular for those concerned about the cosmetic effects of wearing a hearing aid.

Which Features Are Important

In our survey, 53 percent of people who wear hearing aids said that rechargeable batteries were one of the most important features they looked for when purchasing a hearing aid. Smartphone capabilities or tinnitus masking was noted as most important by 43 percent, and 42 percent said automatic noise level adjustment was most important.

Forty-one percent said that the option of multiple program settings was one of the most important features they looked for. Forty percent mentioned advanced microphone features, and 37 percent said wireless connectivity to other devices was most important. Other key features, according to hearing aid experts, include the following:

TelecoilAn option on many modern hearing aids, a telecoil is a small sensor or copper wire that is placed in the hearing aid. When activated, it wirelessly picks up a magnetic signal from hearing-aid-compatible telephones and public address systemssuch as those that may be in conference rooms, concert halls, museums, taxis, and even subway trainsand converts that energy into sound. An audio induction loop, or hearing loop, which is a wire that circles a telecoil-compatible room or space, emits the signal that the telecoil picks up.

Digital Noise Reduction Improves listener comfort and communication in noisy environments by blocking out some background noise. This makes it easier to hear and understand speech, though it is not a fix for all situations.

In-the-ear hearing aids, or in-the-canal , fit either in the bowl-shaped area of the outer ear or, more commonly, in the lower ear canal. This type of hearing aid is best for people with mild to moderate hearing loss, but more advanced accessories are available for anyone with more severe hearing loss.

These devices are easy to handle, come in various sizes, and are more comfortable for people with active lifestyles.

ITE hearing aids are more susceptible to ear wax build-up, clogging, and moisture damage, so its important to follow instructions on caring for your device.

Every Hearing Aid Has Four Key Components



The first major component of every hearing aid is the hearing aid microphone, which picks up sounds from the surrounding environment and converts them into electrical signals.


The hearing aid amplifier increases the overall power or loudness of the signals received from the microphone. Specialized filters and equalizers modify the sounds, so that only sounds relevant for the user are amplified.


Another key component of hearing aids is the receiver, also known as the speaker. It converts the electrical signals from the microphone into acoustic signals heard by the user.


The battery serves as the power source for hearing aids. Hearing aids typically require special batteries that come in a variety of sizes. Hearing aid batteries typically last between 5 to 14 days. Battery life varies depending on the battery size, needs of the user, hearing device, complexity of the users listening environments, amount of usage and more. Today, more and more hearing aids are now rechargeable.
