Understanding Hearing Loss

By: Cindy Erdos, Au.D., CCC-A

Hearing loss can have serious consequences for individuals who experience it, as well as their loved ones.  We know that hearing loss has a negative impact on social, psychological, cognitive, and physical health.  Hearing is crucial to developing meaningful relationships and fully enjoying life.  People who cannot hear well are often cut off from their family, friends, and community.

seniors talkingAccording to the Hearing Loss Association of America (HLAA) approximately 48 million American have hearing loss; 30% of adults 70 or older have hearing loss; and 16% of adult 20-60 have hearing loss.  It is estimated that 1 in 5 America teens have some degree of hearing loss.

Based on this information, you should not be surprised to find yourself in a conversation with an individual with some degree of hearing loss.   Many people believe if you have a hearing loss, getting a hearing aid will fix the problem.  But not everyone with hearing loss is a candidate for hearing aids, and not everyone with a hearing loss is ready for hearing aids.  It may be a surprise to learn that hearing aids are not the only solution for individuals with hearing loss.

As an audiologist, I hear these types of comments from patients and family members almost daily:

  • “I don’t need a hearing aid, everybody mumbles”
  •  “I hear better with my glasses”
  • “Everyone yells at me so I can’t understand”

Let’s look at each statement to try understand what might be happening.

“I Don’t Need a Hearing Aid- Everybody Mumbles”

Understanding hearing loss can help us understand this comment.  There are two main types of hearing loss, conductive hearing loss and sensorineural hearing loss.  Conductive hearing loss is often hearing loss caused by a medical problem such as fluid in the ears or even wax in the ear.  Conductive hearing loss mostly affects how loud sounds are heard.  Conductive hearing loss typically can be medically corrected.

Sensorineural hearing loss is often caused by damaged nerve cells in the inner ear most commonly due to age, noise exposure or hereditary hearing loss.  Sensorineural hearing loss typically cannot be medically corrected and is most likely permanent. For many individuals starting to develop a sensorineural hearing loss, the low frequency sounds are heard at normal or nearly normal level (or volume), but they gradually start losing higher frequency sounds.  For understanding speech, high frequency sounds, or consonants provide a lot of meaning.

Besides the Listener’s hearing loss, another key factor that contributes to the “Everybody Mumbles” comment is caused by the speaker.  Many of us speak very quickly during conversations which causes us to blur our speech.  For an individual who is missing key sounds, conversational speech often compounds the difficulty understanding and can make it nearly impossible to follow the conversation.  Here are two examples of how conversational speech is delivered and received.

“The shiplef ona twowecruise.”   (The ship left on a two week cruise)

“We’re lookin for a whitruck tabuy.” (We are looking for a white truck to buy)

One of the most important things we can do when speaking to someone with hearing loss is to slow down a little bit, speak clearly, and pause between phrases or key words. 

“I Hear Better With My Glasses”

When speaking with someone with a hearing impairment, remember they may benefit tremendously by being able to watch your lips as you speak. To assist them make sure you are within 3-6 feet; face them ensuring the visible features of speech are available; do not cover your mouth with your hands other objects; and make sure there is good lighting.  Remember, “I hear better with my glasses on” because I can see your face better.

“Everyone Yells at Me so I Can’t Understand”

Having hearing loss does not mean someone can tolerate sounds louder than someone with normal hearing.  There are a few reasons louder is not always better for someone with a hearing loss.  The first is due to something called “recruitment.”  Related to the damage to the nerve cells, all individuals with sensorineural hearing loss have recruitment.  Very simply, recruitment is when we perceive sounds as getting too loud too fast.   Just as loud sounds can be uncomfortable for someone with normal hearing, loud sounds can be very uncomfortable for someone with hearing loss.

Typically, we yell or speak loudly to someone when we are upset or frustrated.  Speaking very loudly to someone with hearing loss can give the impression that you are angry with them.  No one enjoys being yelled at and it can make the person feel embarrassed about their hearing loss.

If you find yourself in a conversation with someone with a hearing loss, remember it “Takes Two to Tango.”  Your part is to deliver your message in a way to maximize your communication partner’s ability to understand.   Some key points to remember:

  1. Make sure you are within three to six feet from the listener
  2. Get the listener’s attention before speaking
  3. Make your face is visible and look at the listener
  4. Speak slowly and clearly, but do not exaggerate
  5. Louder is not always better

What is Tinnitus?

By: Cynthia Erdos, Au.D., CCC-A , Audiologist

When I was about 7 years old, I remember lying on my bed listening to my brain work. I cannot remember a time when I didn’t hear a little humming, or buzzing in my ears.  Not until I was in graduate school did I realize the sounds I heard was considered a “symptom” of a possible problem in the ear or within the entire hearing system.  When the professor starting discussing something called “tinnitus”, I turned to my fellow grad student and said, “Do you mean when it is quiet, you don’t hear anything?”  She just gave me a funny look and nodded.

For me, the humming or sounds of crickets is just something I have always heard. If the sounds were suddenly gone, I might be worried and wonder what was happening.  I can only imagine if your ears have been quiet since you can remember, and suddenly you heard a buzzing, humming, ringing or any new sound in your ears, it could be disturbing.  The American Tinnitus Association reports over 45 million Americans struggle with tinnitus, making it one of the most common health conditions in the United States.

What is Tinnitus?

Tinnitus is the clinical term used for a sound heard in the head or ear when no external source is present.  It can be constant or intermittent and can be heard in one ear or both ears.  Tinnitus is usually not a sign of something serious.  Tinnitus is a symptom of a dysfunction with the auditory (hearing) system and is usually associated with some degree of hearing loss.

For some individuals, tinnitus can be a debilitating condition.  It can negatively affect a person’s overall health and social well-being.  Tinnitus has been associated with distress, depression, anxiety, sleep disturbances or even poor concentration.

What causes tinnitus?

There are many causes for tinnitus.  Almost any condition that can cause hearing loss can cause tinnitus.

The most common cause of tinnitus is exposure to loud noise-it is very important to protect your ears from noise.  Some other causes include:

  • Meniere’s disease
  • TMJ disorders
  • Head injuries or neck injuries
  • Obstructions in the middle ear
  • Ear wax
  • Middle ear fluid
  • Tumors of the head or neck
  • Blood vessel disorders
  • High blood pressure
  • Atherosclerosis
  • Medications, including over the counter
    • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
    • Certain antibiotics
    • Certain cancer medications
    • Water pills and diuretics
    • Quinine-based medications

Treating the cause of tinnitus often eliminates tinnitus.  Unfortunately, often the cause of tinnitus is related to permanent damage to the hearing system, such a noise exposure, or the cause is unknown.

Is there a cure for tinnitus?

It is important to understand that tinnitus is a symptom, not a disease or condition.  The most effective way to treat tinnitus is to treat the underlying cause of the tinnitus.  For many people, however, it is impossible to know the exact cause of tinnitus.  If you have tinnitus, you should be evaluated to determine if there is a treatable medical condition.  A thorough tinnitus evaluation often includes a medical examination by an otolaryngologist and a hearing evaluation by an audiologist.   Currently, there is no safe and consistent way to cure tinnitus.  There are evidence-based practices to help patients improve quality of life by learning to manage tinnitus, or manage their reactions to the tinnitus.

There are many ways to learn to manage tinnitus.  Research studies show the best ways to manage tinnitus include education, sound therapies and counseling. For example, be aware of the toys your child plays with, as some can be very loud for little ears. The Sight & Hearing Association releases an annual list of the loudest toys that you can check before making holiday or birthday gift lists.
