Living with hearing problems can be an inconvenience and yet so many people continue to put up with their problems without seeking a solution. In the last few years, the technology and knowledge of hearing health has advanced drastically. Due to this, those with hearing problems can reap the rewards! If you would like to learn more about hearing aids and audiology, you can call Baker Audiology & Hearing Aids at 605-306-5756. Our team of dedicated audiologists are on hand to deal with your needs.

Behind The Ear Hearing Aids

Behind the ear hearing aids are the most common type.

Theyre made up of a small plastic device that sits behind your ear.

This is attached with a tube to a piece of plastic that fits in your ear or a soft tip that goes into the opening of your ear .

BTE hearing aids are one of the easiest types to use and are suitable for most people with hearing loss. Theyre available in a range of colours.

Causes Of Hearing Loss

Despite what you might think, old age is not the only reason a person experiences hearing loss. Sensorineural, conductive, and mixed hearing loss have a variety of causes.

Sensorineural hearing loss represents about 9 in 10 cases of reported hearing loss. Age-related hearing loss is the most common form of SNHL, and noise-induced hearing loss is the second.

The second most common type of hearing loss is called conductive. This is when something physically blocks or damages the ear and keeps sound from reaching the inner ear.

Ever had a bad ear infection and had to suffer through muffled underwater sounds till it got better? Thats a good example of conductive hearing loss. A few others include water blocking your ear, Eustachian tube dysfunction, or just too much wax in there.

Conductive hearing loss isnt usually permanent. It often gets better once you address the underlying problem. Its often hard to figure out what that problem is without consulting a general practitioner or an audiologist.

Finally, you may be suffering from mixed hearing loss. This is when sensorineural and conductive hearing loss happens at the same time. Again, getting your hearing tested will be the first step in figuring out whats causing the problem.

Considerations When Purchasing A Hearing Aid

A medical examination is required before purchasing a hearing aid. Hearing aids can be purchased from an otolaryngologist , an audiologist , or an independent company. Styles and prices vary widely. The National Institute on Deafness and Other Communication Disorders recommends asking the following questions when buying hearing aids:

  • Can the hearing loss be improved with medical or surgical interventions?

  • Which design will work best for my type of hearing loss?

  • May I “test” the hearing aids for a certain period?

  • How much do hearing aids cost?

  • Do the hearing aids have a warranty and does it cover maintenance and repairs?

  • Can my audiologist or otolaryngologist make adjustments and repairs?

  • Can any other assistive technological devices be used with the hearing aids?

Referral To A Specialist

Your GP may refer you to an ear, nose and throat specialist or an audiologist . The specialist will carry out further hearing tests to help determine what’s causing your hearing loss and recommend the best course of treatment.

Some of the hearing tests you may have include a:

  • tuning fork test
  • pure tone audiometry

These tests are described below.

Youve Suffered A Head Injury Or Accident

Sudden and violent head injuries, such as those resulting from car accidents or blows to the head, can result in hearing loss. Internal trauma can damage auditory pathways to the brain, which affects the way sound is received. The brain can be good at compensating for this kind of injury, but a hearing test can help you understand if a head injury has resulted in hearing loss.

Hearing Loss In Adults: Differential Diagnosis And Treatment

THOMAS C. MICHELS, MD, MPH, Olympic Medical Center, Port Angeles, Washington

Am Fam Physician. 2019 Jul 15 100:98-108.

More than 30 million U.S. adults, or nearly 15% of all Americans, have some degree of hearing loss.1 It is most common in older adults, occurring in about one-half of adults in their 70s and 80% of those 85 years and older.1,2 Despite this high prevalence, hearing loss is underdetected and undertreated. Only about one-third of people with self-reported hearing loss have ever had their hearing tested, and only 15% of people eligible for hearing aids consistently use them, citing factors such as cost, difficulty using them, and social stigma.1,3,4

WHAT IS NEW ON THIS TOPIC

The FDA Reauthorization Act of 2017 allows direct-to-consumer sale of hearing aids for mild to moderate hearing loss, for which limited outcome studies show improved hearing, communication, and social engagement. The cost of over-the-counter hearing aids is expected to range from approximately $200 to $1,000 compared with $800 to $4,000 for conventional hearing aids.

Among patients with dementia in a U.S. population-based longitudinal cohort study, the use of hearing aids was associated with decreased social isolation and a slower rate of cognitive decline, even after adjusting for multiple confounders.

Measuring Decibels And Perceived Volume

Severe to profound hearing loss: How can new technologies help you?

A linear scale is more relatable for most people as we often encounter it in our daily lives. An example of a linear scale is a ruler measuring distance. The markings on a ruler are of equal distance to one another, making them linear.

A logarithmic scale is not linear and represents exponents of a base number. You might remember exponents from maths class in school. An example is 5 to the power of 2, where 5 is the number and 2 is the exponent explaining how many times to use the number in a multiplication. In which case it is 5 x 5 = 25.

In the case of decibels , for every 10-dB rise, there is a 10-fold increase in sound intensity, and we perceive this as being 2-times louder in volume.

The below table shows the logarithmic scale in more detail.

Percieved Volume
10 times the sound intensity 2 times as loud
Whisper at 1 m distance 20 dB
1,000 8 Unlimited
4096 9 seconds

A normal face-to-face conversation is about 60 dB. The siren from an ambulance is about 120dB, and its unsafe to listen to up close for longer than 9 seconds.

The increase in sound intensity or the extra energy it takes to produce the sound from 60 dB, and 120 dB is 1-million times! And you would perceive the volume increase as being 64 times louder.

All of this might sound a little complicated, but dont worry, it sometimes confuses the best of us! The important things to remember are:

How Is Hearing Loss Diagnosed

The very first step of the journey is to take a detailed medical history and fill out a lifestyle questionnaire. This will help us identify if there is a potential cause of the hearing loss and also understand your needs and requirements. Next we use video-otoscopy to take images and check the health of the outer ear canal and tympanic membrane or eardrum. This will also indicate if it is safe to proceed with further tests.

We then determine how well you process sound by performing speech tests and recording your responses to a series of different word lists.

As the number one reason for booking a hearing test is trouble hearing in noise, we then perform what is probably the most important test of all, a speech in noise test. This is where a recorded series of sentences is played through headphones or ear inserts and you respond by repeating what you think that sentence is. The number of words correctly repeated is recorded. Each subsequent sentence has more background noise to replicate the real life situations you find yourself in. The results of all our speech tests give a percentage score of your ability to hear.

The next test is the main reason for booking in the first place, the audiometric test. This is performed in a soundproof booth or soundproof room.

All of our fundamental tests may determine further tests or consultations are required depending on results and treatment plans suggested.

Why Is My Hearing Aid Not Covered By Insurance

These life-changing devices can make you more independent and connect with the world around you. However, insurance providers often view hearing aids as a risky investment. Basically, they don’t always consider hearing aids a safe bet. To them, hearing aids are expensive and can get lost easily, making them risky for insurance companies who want your money but not any claims that may arise from it in the future. They also cite that Hearing Aids may require costly repairs or replacements every five years.

Can My Friends And Family Help Me

You and your family can work together to make living with hearing loss easier. Here are some things you can do:

  • Tell your friends and family about your hearing loss. The more friends and family you tell, the more people there will be to help you cope with your hearing loss.
  • Ask your friends and family to face you when they talk so that you can see their faces. If you watch their faces move and see their expressions, it may help you to understand them better.
  • Ask people to speak louder, but not shout. Tell them they do not have to talk slowly, just more clearly.
  • Turn off the TV or the radio when you aren’t actively listening to it.
  • Be aware of noise around you that can make hearing more difficult. When you go to a restaurant, for example, don’t sit near the kitchen or near a band playing music. Background noise makes it hard to hear people talk.

Working together to hear better may be tough on everyone for a while. It will take time for you to get used to watching people as they talk and for people to get used to speaking louder and more clearly. Be patient and continue to work together. Hearing better is worth the effort.

Do I Need A Hearing Aid Expert Guide From Audiologists

Hearing aids are powerful tools for hearing loss treatment, but very few people who need them use them. According to UK charity HearingLink, around 7 million people could benefit from hearing aids, but only 2 million have them.

Have you started to wonder if youre in that group of 5 million individuals who could see huge benefits from getting a hearing aid? This blog contains all the details you need to help you find out.

Hearing Aids For People Who Are Deaf In One Ear

  • CROS aids –aid on one side “pipes” sound to other side, where hearing is better. Most hearing aid users are unenthusiastic about CROS aids, but recent improvements in technology has made them much better There are three types of CROS aids:
  • Wired CROS — while effective, the wire connecting one ear to the other can be annoying.
  • Transcranial CROS — This is only possible in people with one entirely dead ear
  • Wireless CROS — more convenient, vulnerable to electrical interference
  • BAHA — bone-anchored hearing aid. While it can be used like a conventional hearing aid, usually it is used in people who have good hearing on one side and no hearing on the other — thus it is a surgically implanted version of the CROS aid. Most people with unilateral hearing loss are enthusiastic about BAHA aids because it works very well and it is unobtrusive. It requires “very good” hearing on the opposite side. It eliminates the head shadow effect, occlusion effect, and feedback.
  • BAHA . This type of hearing aid works well in persons with severe unilateral hearing loss. The image to the left, from Prosper hospital, shows how a button is inserted into the bone of the skull above the ear. The middle image is from //www.islandhearing.com/bone_anchored_hearing_aids.htm, by Island Hearing. The device is attached to the button within the skull. It is very unobtrusive .

    Model Of Hearing Aid:

    Although some hearing aids may look the same and be the same type, they may have very different technology inside. The newest and most expensive digital hearing aids come with the most up-to-date features and functions, including bluetooth, telephone compatibility, weather protection, and directional speech enhancements. Obviously the more packed with technology, the higher the price, but you may not actually need a high level of technology with many difficult to operate features. This is why it’s important to look around and assess what you actually need from a hearing aid before purchasing one.

    How Do We Hear

    Do I need Hearing Aids for a Mild Hearing Loss?

    Hearing depends on a series of events that change sound waves in the air into electrical signals. Your auditory nerve then carries these signals to your brain through a complex series of steps.

  • Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum.
  • The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
  • The bones in the middle ear couple the sound vibrations from the air to fluid vibrations in the cochlea of the inner ear, which is shaped like a snail and filled with fluid. An elastic partition runs from the beginning to the end of the cochlea, splitting it into an upper and lower part. This partition is called the basilar membrane because it serves as the base, or ground floor, on which key hearing structures sit.
  • Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane. Hair cells-sensory cells sitting on top of the basilar membrane-ride the wave.
  • As the hair cells move up and down, microscopic hair-like projections that perch on top of the hair cells bump against an overlying structure and bend. Bending causes pore-like channels, which are at the tips of the stereocilia, to open up. When that happens, chemicals rush into the cells, creating an electrical signal.

    Sign Language And Lip Reading

    If you’ve been deaf from birth or you develop severe hearing loss later in life, it can affect your ability to communicate with other people.

    But you can learn different methods of communicating that can be used instead of, or as well as, spoken English.

    2 of the main methods are:

    • lip-reading where you learn to watch a person’s mouth movements while they’re speaking to understand what they’re saying
    • sign language a visual way of communicating using hand gestures, facial expressions and body language

    Caring For Your Hearing Aid

    Your hearing aids will last much longer if you take good care of them. Some tips to keep in mind:

    • Keep them away from heat, moisture, hair care products, children, and pets.
    • Clean them as directed.
    • Turn off your devices when you are not using them.
    • Replace dead batteries right away.

    Hearing aid batteries may last from several days to a couple of weeks. Battery life depends on the battery type, hearing aid power requirements, and how often you use it.

    In general, hearing aids can last for 3 to 6 years. You may need a new one sooner if your hearing loss gets worse. Behind-the-ear hearing aids give you more flexibility since they can be programmed for a wider range of hearing loss.

    Digital hearing aids get stronger and better every few years as computer technology improves. This often prompts people to upgrade their devices.
